pollution
Comprising over 70% of the Earth’s surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprised of hydrogen and oxygen, life on Earth would be non-existent: it is essential for everything on our planet to grow and prosper. Although we as humans recognize this fact, we disregard it by polluting our rivers, lakes, and oceans. Subsequently, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate. In addition to innocent organisms dying off, our drinking water has become greatly affected as is our ability to use water for recreational purposes. In order to combat water pollution, we must understand the problems and become part of the solution.

According to the American College Dictionary, pollution is defined as: “to make foul or unclean; dirty.” Water pollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water. When it is unfit for its intended use, water is considered polluted. Two types of water pollutants exist.

1. Point sources of pollution occur when harmful substances are emitted directly into a body of water. The Exxon Valdez oil spill best illustrates point source water pollution. A nonpoint source delivers pollutants indirectly through environmental changes. An example of this type of water pollution is when fertilizer from a field is carried into a stream by rain, in the form of run-off which in turn affects aquatic life. The technology exists for point sources of pollution to be monitored and regulated, although political factors may complicate matters.

2. Nonpoint sources are much more difficult to control. Pollution arising from nonpoint sources accounts for a majority of the contaminants in streams and lakes
DEFINITION

"pollution" means such contamination of water or such alteration of the physical, chemical or biological properties of water or such discharge of any sewage or trade effluent or of any other liquid, gaseous or solid substance into water (whether directly or indirectly) as may or is likely to, create a nuisance or render such water harmful or injurious to public health or safety, or to domestic, commercial, industrial, agricultural or other legitimate uses, or to the life and health of animals or plants or of aquatic organisms.
pollution
The major sources of water pollution can be classified as
1. municipal,
2. industrial, and
3. Agricultural.

Municipal water pollution consists of waste water from homes and commercial establishments. For many years, the main goal of treating municipal wastewater was simply to reduce its content of suspended solids, oxygen-demanding materials, dissolved inorganic compounds, and harmful bacteria. In recent years, however, more stress has been placed on improving means of disposal of the solid residues from the municipal treatment processes. The basic methods of treating municipal wastewater fall into three stages: primary treatment, including grit removal, screening, grinding, and sedimentation; secondary treatment, which entails oxidation of dissolved organic matter by means of using biologically active sludge, which is then filtered off; and tertiary treatment, in which advanced biological methods of nitrogen removal and chemical and physical methods such as granular filtration and activated carbon absorption are employed. The handling and disposal of solid residues can account for 25 to 50 percent of the capital and operational costs of a treatment plant.

Industrial water pollution. The characteristics of industrial waste waters can differ considerably both within and among industries. The impact of industrial discharges depends not only on their collective characteristics, such as biochemical oxygen demand and the amount of suspended solids, but also on their content of specific inorganic and organic substances. Three options are available in controlling industrial wastewater.

1. Control can take place at the point of generation in the plant.
2. Wastewater can be pretreated for discharge to municipal treatment sources.Wastewater can be treated completely at the plant and either reused or discharged directly into receiving waters.
pollution
Cleaning wastewater effluent is an important aspect of water pollution control efforts. The primary treatment includes screening, grit removal and sedimentation.
The secondary or biological treatment consists of a trickling filter, activated sludge process or extended aeration process like aerated lagoons or oxidation ditches. A natural self-purification process using algae-bacterial symbiosis is referred to as stabilization pond. More recently, a device known as Rotating Biological Contactor has been developed as a low-cost wastewater treatment system.
Tertiary or advance treatment includes the removal of suspended solids, dissolved organic compounds and dissolved inorganic plant nutrients and minerals. Microstraining, precipitation, adsorption, electrodialysis, reverse osmosis and chlorination are some of the processes in this category. A dissolved air floatation unit has been developed for removal of some of the suspended and dissolved impurities in water.


Wastewater Treatment
Raw sewage includes waste from sinks, toilets, and industrial processes. Treatment of the sewage is required before it can be safely buried, used, or released back into local water systems. In a treatment plant, the waste is passed through a series of screens, chambers, and chemical processes to reduce its bulk and toxicity. The three general phases of treatment are primary, secondary, and tertiary. During primary treatment, a large percentage of the suspended solids and inorganic material is removed from the sewage. The focus of secondary treatment is reducing organic material by accelerating natural biological processes. Tertiary treatment is necessary when the water will be reused; 99 percent of solids are removed and various chemical processes are used to ensure the water is as free from impurity as possible.






Hydrology ProjectThe project is funded by the World Bank and the Netherlands Government . The project covers Gujarat, Madhya Pradesh, Maharashtra, Orissa, Andhra Pradesh, Tamil Nadu, Karnataka and Kerala. The beneficiaries are Central and State government organisations - Central Water Commission (CWC), Central Water and Power Research Station (CWPRS), Central Ground Water Board (CGWB), State Surface Water Department (SSWD), State Ground Water Department (SGWD), State Ground Water Survey and Investigation (SGWSI), Ground Water Survey and Development Agency (GSDA) and Water Resources Department (WRD) under the Ministry of Water Resources, Government of India. The objectives of the project are to develop a comprehensive, easily accessible and user-friendly data bases covering all aspects of hydrological cycle including surface and ground water in terms of quantity, quality and climatic measurements, particularly of rainfall, through a network of a total of about 299 laboratories. This would assist in the development of more reliable and specifically intensive data on water resources and making information available for planning and management of water resources. The goal is to be achieved by improving institutional and organisational arrangements, technical capabilities and physical facilities available for collection, processing and exchange of hydrological, hydro-geological and hydro-meteorological data

pollution

Ninety-five percent of all fresh water on earth is ground water. Ground water is found in natural rock formations. These formations, called aquifers, are a vital natural resource with many uses. Nationally, 53% of the population relies on ground water as a source of drinking water. In rural areas this figure is even higher. Eighty one percent of community water is dependent on ground water. Although the 1992 Section 305(b) State Water Quality Reports indicate that, overall, the Nation’s ground water quality is good to excellent, many local areas have experienced significant ground water contamination.
Ground Water Quality Status

GROUNDWATER QUALITY SERIES: GWQS/ 09/2006-2007

In recent years, the increasing threat to groundwater quality due to human activities has become a matter of great concern. A vast majority of groundwater quality problems present today are caused by contamination and by over-exploitation, or by combination of both. Rapid urbanization and industrialization in India has resulted in steep increase of generation of wastes. Due to lack of adequate infrastructure and resources the waste is not properly collected, treated and disposed; leading to accumulation and infiltration causing groundwater contamination. The problem is more severe in and around large cities as also various clusters of industries. In many of these areas groundwater is only source of drinking water, thus a large population is exposed to risk of consuming contaminated water. In this background Central Pollution Control Board with the help of its Zonal offices, the National Institute of Hydrology (NIH) and the Pollution Control Research Institute (PCRI) of Bharat Heavy Electricals Ltd. (BHEL) initiated a detailed survey of groundwater quality in problem areas of industrial clusters and metro cities of India. The results of this Survey with respect to 16 problem areas and 8 metro cities are summarized in this Report.
The Report presents the environmental profiles of metropolitan cities and Problem Areas identified by CPCB and their groundwater quality status. The groundwater quality data obtained during Survey were evaluated against drinking water quality requirements [BIS 10500, (1991) & WHO (1996) Standards]. Salinity, nitrate, Coliform & Fluoride are the main water quality issues in the metro cities and problem areas of the country. Considering the competing demand on this scarce resource, the Report highlights the judicious use of groundwater and also remedial measures needed to overcome the problems.

Ahmedabad, seventh largest populous city of India and Commercial Capital of Gujarat State has unique identity recognize by River Sabarmati and Gandhi Ashram established on its western Bank (Famous World over by Name Satyagrah Ashram). Sultan Ahmad Shah established the city in 1411. The City is spared over area of 190.84 Sq. Km. The River Sabarmati flows from north to south in the center of the city and splits the city in almost two equal parts. The city encompasses Population of about 4.5 million. Ahmedabad experiences hot and arid climate with scanty Rainfall. River Sabarmati is backbone of the development of Urban Sprawl of Ahmedabad.




At present the riverfront lies neglected and characterized by unimaginative and unplanned development. It’s potential to provide city level social infrastructure and recreation facilities lie untapped. Though it is a major source of water for the city and despite the building of a major barrage to retain water, except for a few months during the monsoon the river is dry. Sewage contaminated storm water out-falls and the dumping of industrial waste pose a major health and environmental hazard. Though the riverbanks and bed provide a place to stay and source of livelihood for many poor citizens, the riverbank slums are disastrously flood prone and lack basic infrastructure services. The slums located along the riverbed also pose a major impediment to efficient management of monsoon flood sin the river.
It has long been acknowledged that appropriate development of the riverfront can turn the river into a major asset, which can improve the quality of environment and life in Ahmedabad and improve the efficiency of its infrastructure. In May 1997, the Ahmedabad Municipal Corporation established the Sabarmati River Front Development Corporation Limited (SRFDCL) under Section 149 (3) of the Companies Act 1956. The SRFDCL was provided with seed capital of Rs. one crore and charged with the responsibility of developing the Sabarmati Riverfront. In August 1997, the SRFDCL appointed Environmental Planning Collaborative (EPC) a city based not for profit urban planning and urban development management consulting firm to prepare a comprehensive proposal for the development of the Sabarmati Riverfront.

Gujarat Pollution Control Board was constituted by the Government of Gujarat on 15.10.1974 with a view to protect the environment, prevent and control the pollution ofwater in the State of Gujarat, that occupies a prominent niche in progressive and industrialdevelopment of the country. The Board has been over 30 years entrusted with the CentralActs and relevant Rules for pollution control as notified thereof from time to time.

As reported before, the Board had staff of 25 in October 1974, initially. Though, thestaff strength has increased to 465, yet it is far less than that required by the Board to implement aforesaid laws. As of today, there are 92 engineers and 148scientist and analysts.

The Board is having its Head Office and Central Laboratory at Gandhinagar. Out of total ten Regional Offices, six attached with laboratory facilities are located at Vadodara, Bharuch, Surat, Vapi, Rajkot and Jamnagar. Regional Offices Godhara, Mehsana, Ahmedabad and Bhavnagar are being equipped with analytical facilities. The Head Office performs activities concerning general polices and enforcement of various provisions of the Acts as well as general administration and co-ordination with other agencies. The Central Laboratory at Gandhinagar was providing facilities for analysis of samples collected by both RO, Ahmedabad as well as RO, Mehsana, besides being involved in development of methods for analysis of water, wastewater, gases and hazardous waste samples.

Objectives

The major objectives of the Board are centred around the Pollution Control and the protection of the environmental quality. These are outlined as under:
· Bring about all round improvement in the quality of the environment in the State by
effective implementation of the laws.
· Control of pollution at source to the maximum extent possible with due regard to
technological achievement and economic viability as well as sensitivity of the receiving
environment. This objective is being fulfilled through laying down the disposal standards as
well as gaseous emission standards.
· Identifications of sites and development of procedures and methods for the disposal of
hazardous wastes.
· Maximizations of re-use and re-cycle of sewage and trade effluent on land for irrigation and
for industrial purpose after giving appropriate treatment and thereby economizing and
saving on the use of water. The practice also helps in stopping pollution of water due to
reduction in discharges of waste into water bodies.
· Minimisation of adverse effect of pollution by selecting suitable locations for the
establishment of new industrial projects.
· Co-ordination with other agencies of the State Government and local authorities to
encourage the Common Effluent Treatment Plants and Treatment Stabilisation Disposal

Facilities.

pollution
Industrial estates of Gujarat are cesspools of filth and environmental health hazards. Yet the government is blindly promoting industry
Gujarat has more than 90,000 industrial units, according to the state government. About 8,000 of these units are polluting, also says the state government. Major polluting industries are located in the Vadodara Petrochemical Complex, Nandesari, Ankleshwar, Vapi, Vatva and Hazira near Surat.
The state government was encouraging small-scale units in the chemicals sector through financial incentives. These industrial units came up in huge numbers. But the government gave a very low priority to the environment. This is why environmental problems cropped up in Gujarat.
Nowhere more so than in the nearly 400-km stretch between Vapi in southern Gujarat and Vatva in northern Gujarat, called the golden corridor, an industrialist’s dream come true. This stretch has become a hot bed of pollution. “In the golden corridor, we have created a number of potential disasters similar to the Bhopal gas tragedy. Another example of an environmental nightmare is Alang, the largest shipbreaking yard of the world, situated 50 km from Bhavnagar. The 11-km coastline of the yard has been severely polluted due to scrapping of hazardous ships.

Government response, or the lack of it
We are suffering because of the lack of proper planning in the past. But it is now a futile exercise to blame anyone for that. The situation is in front of everybody. We have to come out of it. But what is the state government doing to deal with the growing pollution problems? Well, it is trying its best to set up more industries.The state government has planned the ‘Infrastructure Vision 2010’, which hardly lays any focus on environment. “The ‘Vision 2010’ is a focused and comprehensive document on infrastructure. But environmental concerns in general or anticipated as a consequence of the implementations of the vision have not been even touched upon anywhere.”
Blackened rivers
Gujarat’s rivers are bearing the brunt of industrial pollution, as are the people living on the banks of these rivers. All the major rivers and streams of Gujarat are in a bad state due to effluent discharged by industry, be it the Kolak, the Mahi, the Daman Ganga or the Amlakhadi. One can see red water flowing in the Sabarmati, released by the common effluent treatment plant (CETP) in Vatva. Several times, drug factories in Vapi dump spoilt batches in the open. These contain chemicals that are highly toxic.
Take the case of the farmers from 11 villages between Lali and Navagam, who irrigate their fields with untreated effluents released into the Khari river. Nearly 100 tubewells and borewells have been contaminated. “When factories were prevented from dumping effluents in the Mini river, they resorted to reverse boring, pumping untreated effluents straight into underground aquifers,” says Sahabsinh Darbar, 73, a farmer from Sherkhi village in Vadodara district.

The rise and fall of a people’s campaign
On June 19, 1987, two people who had climbed down to do repair work in a well in Lali village died. The villagers knew the cause of death. Effluents carried by the neighbouring Khari river, better described as an effluent channel, had leached into the groundwater. The reaction had produced poisonous gases, which lead to asphyxiation. The river has been carrying industrial wastes for the past 20 years, says Pravinbhai Jashbhai Patel, a farmer from Navagram village.
A public outcry followed. “But as usual, the government chose to remain silent,” says Patel. Finally, on February 16, 1995, the 11 villages filed a public interest petition in the Gujarat High Court. The bench comprising chief justice B N Kirpal and justice H L Gokhale set up the Pandya Committee to look into the matter. The committee reported that water samples taken from the Khari river, where it flows through Lali, had pH levels as low as 2, showing that the water was highly acidic. The biological oxygen demand was about 14 times the permissible limit and the chemical oxygen demand was much more than 16 times the limit, says Jashbhai Patel.
On the basis of the report, on August 5, 1995, the court ordered that 756 industrial units, which were regarded as highly polluting, pay up 1 per cent of their gross turnover of the year 1993-94 or 1995-96, whichever was higher. The court ruled: “The amount be utilised for the works of socio-economic uplift in the villages and on educational, medical and veterinary facilities and the betterment of the agriculture and livestock in the said villages.”

“But even today, farmers use waters from the polluted Khari river when water is released from the upstream Kadana dam,” says Girish Patel, a lawyer based in Ahmedabad. As for compensation, sources point out that while some industrial units have paid up, others are still in the process of doing so. Several units have started production again. The situation has not changed at all. Untreated effluents still flow in the river.

Water in the 100-odd wells near Khari is still a distinct red. Kanubhai Patel, a farmer, says the paddy yield has gone down by half. The villagers find a difference in milk quality, too, which they attribute to cattle grazing in contaminated areas.

In August 1999, Down To Earth got a sample of groundwater from Lali village analysed at the Facility for Ecological and Analytical Testing (FEAT) of the Indian Institute of Technology, Kanpur. It had a mercury concentration that was 211 times the permissible limit. Mercury is an extremely toxic heavy metal and is known to cause damage to kidneys and the central nervous system.

Failure of the courts
The most damaging aspect of Gujarat’s struggle against industrial pollution has been the failure of the courts to deliver. There was a phase in 1995 when the Gujarat High Court was cracking down on polluters, giving an impetus to the environmental movement in the state. Hundreds of cases were filed in the court. This continued for two to three years. As long Justice B N Kirpal was the chief justice of the high court, he took stern action against polluters.

After this period, the court got bogged down in dealing with applications to reopen industrial units after a closure order given by justice Kirpal. But the implementing and regulatory agencies remained lackadaisical. Soon, people handling these cases lost interest as the exercise could not yield the desired results. “In Gujarat, industry controls politicians, rather than the other way round. The situation does not look like it will improve,” says Mayur Pandya. “If we try to find out how many industrialists have been put behind bars under the Water Act or the Air Act, we will hardly find any. So they are not scared at all,” adds Girish Patel.
“The courts usually go by the the findings of GPCB. This is not acceptable at all. The court should stop relying on GPCB information if it wants better results,” says Anand Mazgaonkar of PSS. He says GPCB annual reports look like primary school books: “These are not the kind of reports needed in a state where so many industries produce extremely toxic chemicals.”

Waste: solid and hazardous
Factories have been dumping thousands of tonnes of hazardous wastes in the open. Not only has this polluted the groundwater but it has also damaged fertile lands. Take the case of Bajwa, a village in Vadodara district where industrial waste has been accumulating for the past 30 years and there is barely any agricultural land to be proud of in terms of productivity. Now, industries are constructing landfill sites. But even in the construction and planning of these, environmental health has not been kept in mind. One example is GIDC’s Nandesari Industrial Estate north of Vadodara. Plans of a site to dump toxic wastes are severely flawed and there are fears of a major ecological disaster.
From Vapi to Mehsana, several units dealing with pharmaceuticals, dyes and dye intermediaries are constructing landfills sites to dump their hazardous wastes. However, in 1977 study conducted for the us Environmental Protection Agency, conducted on 50 landfills, showed that 86 per cent had contaminated underground water supplies beyond the boundaries of the landfill.

Environment impact assessments by the National Productivity Council, Gandhinagar, in 1997-98 and 1997-98 showed high levels of lead contamination in the groundwater of Nandesari. Samples taken nearby the gidc dump contained 38.25 milligramme per litre (mg/l) of lead, whereas the permissible limit is a mere 0.05 mg/l for drinking water. The groundwater has been severely contaminated to a depth of about 60 metres, the study says.
“Disposal of untreated mercury-contaminated effluent from caustic manufacturers has contaminated large tracks of land in Nandesari in Gujarat,” says a draft Sectoral Environment Report submitted in 1997 by the Union ministry of environment and forests to the World Bank.

Systems that do not work
“The entire machinery to control pollution in the state has failed,” says Girish Patel. “The view of the ruling party is that environmental problems are just a problem of the elite. They do not accept that the poor people are the most severely affected because it is they who live in a polluted environment and drink contaminated water,” he adds.GPCB is the one of the worst pollution control boards in India. It has mainly political appointees or bureaucrats at senior positions, who lack knowledge of environmental issues,” rues . “It is an irony that only the first two chairpersons of GPCB had any background in the field of the environment. I was the second chairperson during 1980-82. Recently either bureaucrats or the political appointees have been appointed. “There is no pressure from the implementing agencies over industrialists. They do not have an initiative to meet the environmental norms,” he adds. This has certainly helped big industries find ways to flout environmental norms. Today, industrialists first invest money in a project and then plead in the court that they cannot stop the work on environmental grounds as they have already made the investment. “In most of the cases, the court relaxes some of the norms. As a result, what happens is that the pollution remains, but the conditions disappear,” comments Patel.

A fatigued civil society

“The NGOs that are working in this field do not have the support to do anything concrete. So, by and large, there is no strong voice against pollution problems in Gujarat today,” says Girish Patel. D S Ker, president of Gramya Vikas Trust, an NGO based in Dwarka, says: “NGOs here have not been able to mobilise grassroots-level support. The voice of ngos in the state mainly comes from the middle class. But these people have not been able to carry together the grassroots level people.”

Although people of Gujarat are gradually realising that pollution is becoming a serious problem, they are not reacting the way they should, considering that their very lives are at stake. The spirit of public good that saw numerous people going to court against polluting industry has been snuffed out after implementing agencies failed to enact the orders of the courts.

A way out?
Michael Mazgaonkar says the only way out of the present situation is to have a very democratic system of permitting industries: “If we can ensure this along with easy access to information, we can reduce the problem to a great extent. We have adequate environmental rules that, if implemented properly, can control most of the industrial hazards. But the industries have found ways to circumvent these rules. So even if all these rules are implemented and the decision-making is not democratic, the problem is likely to continue,” he feels.“The problem can only be dealt with if good ngos and people take up the issue seriously. If community-based organisations come up, then some improvement can be made in the present situation,” says . C J Jose, member secretary of GEC, has another view: “To protect their trade at the international level, these industries will be forced to comply with international environmental norms.”

Gujarat clearly needs direction today when it comes to environmental governance. The civil society is faced with a huge task. The first thing to do, however, is to involve rural communities and industrial workers in the struggle against pollution. That being done, solutions will emerge. But if that is not done, then the cesspool is only going to worsen.




A river becomes an effluent channel

It has been a long struggle for the people living in the villages of Sajod, Pungam, Matiad and Haripura in Bharuch district of Gujarat. The Amlakhadi river — which was one of the sources of water for these villages — has today become an effluent channel.

For several years, more than 1,500 industrial units in Jhagadia, Ankleshwar, Panoli, Vilayat and Dahej of Bharuch district have been discharging effluents into the Amlakhadi. The river meets the Narmada river near Bharuch. More than half of them are chemical units that manufacture dyes, paints, fertilisers, pharmaceuticals, industrial chemicals, paper and pesticides.

The 1994-95 annual report of the Gujarat Pollution Control Board (GPCB) says that the chemical oxygen demand (cod) level in the Amlakhadi river is 11,007 milligramme /litre (mg/l) when the prescribed GPCB level is only 250 mg/l. Even the biological oxygen demand (bod), which stands at 442 mg/l, far exceeds the GPCB limit of 30 mg/l. Moreover, a study conducted by environment pressure group, Greenpeace, has found toxic metals such as lead, mercury, chromium and zinc in the effluents released into the Amlakhadi. During monsoon, the effluents sometimes overflow and destroy the farmlands.


For many years the villagers have been protesting against the poisoning of the river. In December 1996, the Centre for Environment, Science and Community (cescom), a Vadodara-based non-governmental organisation (ngos), helped the villagers bring the struggle onto the negotiation table with the government. “We held a series of discussions with the district collector, officials from the Gujarat Industrial Development Corporation (gidc) and representatives from the industries. Later it was decided that no new units would be allowed in the Jhagadia Industrial Estate, except the existing four units unless an effluents pipeline was laid down for Ankleshwar, Panoli and Jhagadia estates. This pipeline was supposed to take effluents from these estates directly into the sea,” says Ashok Rathi, secretary, cescom.

But when the gidc allowed more industries to come up in Jhagadia even before the pipeline was laid, Jayesh Patel, a member of Narmada Pradushan Nivaran Samiti, an organisation associated with cescom, filed a public interest litigation (pil) in the Gujarat high court. The Ankleshwar Industrial Association (aia) estimates that its members generate between 250-270 million litres per day (mld) of effluents. Of this 58 per cent is generated from the manufacture of dyes and dye intermediates; 10 per cent from drugs and pharmaceuticals; and five per cent from inorganic chemicals, says a 1996 Central Pollution Control Board report.However, many industrial units claim to have installed effluent treatment plants. There is a common effluent treatment plant (cetp), backed by United Phosphorus Limited (upl) which has nearly 192 members. The cetp has a capacity to treat around 1,000 cubic metres of effluents per day or 1 mld. The industrial units are also planning a 55-km long pipeline project that will discharge effluents from Ankleshwar, Panoli and Jagadia into the sea. This pipeline will take the effluents 14 km inside the sea.

“The high court had passed an interim order two years ago asking the industrial units to stop dumping effluents. However, the units have not stopped dumping,” says Rathi. “After this judgement, no new industry will be allowed in the area to discharge effluents in Amlakhadi until the GPCB develops norms in compliance with Section 17-1-K of the Water (Prevention and Control of Pollution) Act of 1974, as laid down by the court,” adds Rathi.

“We had brought to the notice of the high court that the Water Act section 17-1-(K) allows consent to be given only subject to tolerance limits of the stream where discharge is to be made,” he says. Thus the decision of the high court upholding the stand taken by gidc in not allowing any other industry to discharge effluent before the pipeline is commissioned remained in force during full period of litigation, Rathi adds.
pollution
The rapid pace of industrialization and the greater emphasis on agricultural growth for overall development have brought in a host of environmental problems in recent years in India. Financial and technological constraints have led to inefficient conversion processes, thereby leading to generation of larger quantities of waste and resulting pollution. The concentration of industries in certain pockets and the skewed distribution of rainfall have further compounded the scenario. Thus, India encounters water quality problems both on account of water pollution and overexploitation of groundwater.

Government Measures on Water Pollution Control

Major industries in India responsible for water pollution are fertilizers, sugar, textiles and chemicals, mines and minerals, pulp and paper, leather tanneries, and process industries. Pollution problems in India are addressed by a combination of legislative, punitive, and motivational measures. The government of India has enacted a number of pieces of legislation, such as the Water (Prevention and Control of Pollution) Act, 1974 and amended in 1988; the Water (Prevention and Control of Pollution) Cess Act, 1977 and amended in 1991; and the Environment Protection Act, 1986, etc. The problem is compounded by the presence of a large number of small-scale industries. A system of environmental audit has therefore been introduced to enable the production units to evaluate the raw materials, utilities, and operational efficiencies to effect any possible midcourse corrections and minimize environmental pollution. Imposition of cess for water required and wastewater produced represent the punitive measures that would force the industries to reduce the pollution load. At the same time, the government has come out with a number of schemes to encourage setting up of treatment plants to mitigate the pollution load through subsidies and soft loans.

Water Pollution Mitigation by Industries

Initially, the affected industries directed their efforts to treat their effluents so as to meet the discharge norms such as MINAS (minimum allowable standards), usually defined in terms of temperature, pH, BOD, COD, suspended loads, and toxic constituents such as mercury, chromium, cadmium, etc. The norms are different for inland and coastal discharges. Large- and medium-scale industries have their own infrastructure and resources, and they have adopted their own effluent treatment schemes so as to render their discharge streams environmentally safe.

Small-scale industries, because of their limited resources in terms of finance, space, and technology, cannot afford to treat their wastes. The concept of Common Effluent Treatment Plant (CETP) was evolved to provide necessary assistance to this sector, wherein the wastes generated by a number of industries are brought together to a central place and treated. A number of plants are in operation in different parts of India. Significant variations in the composition of the wastewater arising from a cluster of industries has created difficulties in ensuring the efficiency and effectiveness of the CETP. Insisting on a pretreatment system by the individual industries to ensure consistency of the composition of effluents would defeat the very purpose of CETP. With the knowledge that the addition of domestic sewage improves the treatability of industrial wastewater, a new approach, referred to as a Combined Effluent Treatment Plant, has evolved, wherein the domestic sewage of the surrounding community is jointly treated with the industrial wastewater1.

Water Management in Indian Industries
The migration of population and the clustering of industries around urban centers have escalated the demand for good-quality water, both for industrial and domestic use. Inadequate natural resources and increased generation of sewage have created problems, both in the supply of water and disposal of sewage, forcing the government to increase the water charges and effluent cess. In urban centers, a dual pricing system for water is being adopted, whereby water for domestic consumption is charged less. Furthermore, industries are encouraged to set up water recovery or desalination plants to meet their demands. Consequently, industry has not only started adopting measures to minimize waste, but also has been looking for various means by which they can recover and recycle their wastewater. Some industries, such as Rashtriya Chemicals and Fertilizers Ltd., have successfully experimented to recover and reuse water from their regenerant waste streams using reverse osmosis and are in the process of setting up large-capacity plants.

Role of Membranes in Water Recovery and Reuse
Membrane processes, with their variety and flexibility, are characterized by ambient temperature operation, low energy consumption, and modular nature. The physicochemical mechanism of separation requires only limited use of chemicals, making the process eco-friendly. In some cases, the processes allow the recovery of valuable chemicals for reuse. Membranes are available in the market covering a wide range of characteristics. Water recycling and reuse, in this context, has assumed greater significance. Thus, industries have resorted to methods whereby they can recover and reuse water. The general scheme2 followed, as shown below, consists of preliminary, primary, and secondary treatments for the reduction of suspended matter andbio-contaminants.
A scheme consisting of reverse osmosis at the tertiary treatment stage has been adopted on a trial basis by Madras Fertilizers Ltd. (MFL) and Madras Refineries Ltd. (MRL) to recover good-quality water from sewage. The water thus recovered is being used as a boiler feed after polishing through demineralizers. This process has encouraged the state government to adopt the scheme for Chennai, traditionally a water-starved city in India, for recycling about 30 MGD of water for industrial use.

Management of Drinking Water
The overexploitation of groundwater has particularly affected the availability of good-quality drinking water in remote villages of India. A significant number of villages have problems related to brackishness and contamination by iron, fluoride, arsenic, etc. Rain harvesting and groundwater recharge techniques are being encouraged to make the villages self-sufficient, but they have limited potential. Membrane processes, such as reverse osmosis and electrodialysis, have been widely adopted for the provision of drinking water for salinity-affected villages, but a number of improvements are required in order to simplify the operating features so as to absorb the technology under the rural infrastructural constraints.

Future Scenario
It is expected that in the future all process industries will have water recycling plants and coastal industries may adopt seawater desalination plants either using process waste heat or reverse osmosis membranes. Domestic water requirements would be met with natural resources, while industrial requirements may have to be supplemented by desalination.


Assessment of the Current Technology
Membrane technology, though originally developed for desalination, has made a major impact in a number of industrial separations. With reference to desalination and effluent water treatment for reuse, the technology is considered mature enough for large-scale exploitation. Whether for domestic use or industrial process water requirements, the cost of desalted water, however, continues to be an area of attention. Cost-reduction strategies include reduction in process energy requirements by adopting/integrating energy-recovery systems and enhancing permeate recovery through better feed water pretreatment practices and employing high-salt rejecting membranes. These measures are partially adopted for seawater desalination in India.
Seawater desalination on a large scale is generally considered for industrial process water needs in India rather than for domestic use. For small-capacity brackish water desalination in rural inland areas, membrane technology is at present facing a setback owing to the higher cost of water produced and operational problems such as nonavailability of skilled manpower needed for plant operation and frequent electric power breakdowns. Regarding effluent water treatment for reuse in industries, membrane technology is most suited for Indian conditions and is being rapidly adopted.
pollution
Estimates suggest that nearly 1.5 billion people lack safe drinking water and that at least 5 million deaths per year can be attributed to waterborne diseases. With over 70 percent of the planet covered by oceans, people have long acted as if these very bodies of water could serve as a limitless dumping ground for wastes. Raw sewage, garbage, and oil spills have begun to overwhelm the diluting capabilities of the oceans, and most coastal waters are now polluted. Beaches around the world are closed regularly, often because of high amounts of bacteria from sewage disposal, and marine wildlife is beginning to suffer.






















Perhaps the biggest reason for developing a worldwide effort to monitor and restrict global pollution is the fact that most forms of pollution do not respect national boundaries. The first major international conference on environmental issues was held in Stockholm, Sweden, in 1972 and was sponsored by the United Nations (UN). This meeting, at which the United States took a leading role, was controversial because many developing countries were fearful that a focus on environmental protection was a means for the developed world to keep the undeveloped world in an economically subservient position. The most important outcome of the conference was the creation of the United Nations Environmental Program (UNEP).





















UNEP was designed to be “the environmental conscience of the United Nations,” and, in an attempt to allay fears of the developing world, it became the first UN agency to be headquartered in a developing country, with offices in Nairobi, Kenya. In addition to attempting to achieve scientific consensus about major environmental issues, a major focus for UNEP has been the study of ways to encourage sustainable development increasing standards of living without destroying the environment. At the time of UNEP's creation in 1972, only 11 countries had environmental agencies. Ten years later that number had grown to 106, of which 70 were in developing countries.
pollution

On one level, the community-based water management research program focuses on a broad array of emerging water problems, such as groundwater overdraft, that threaten basic livelihoods in South Asia and, for that matter, many other parts of the world as well. Problems, such as the 3m/year decline in aquifer levels now common in much of Gujarat, generate conflict both at the very local level between individual users and at higher levels between, for example, urban and rural areas or between states. Specific conflicts of this type are well documented in the book, Rethinking the Mosaic that was produced during the first phase of the project. Looking beyond these immediate tangible conflicts, however, the core challenges lie not in the physical problems themselves or in the conflicts between users and regions but in the social and institutional context determining how society responds to water problems and the conflicts they generate. As discussed in the previous section, three conflicting models of social change dominate most approaches to water – and other natural resource – management. These models are also ideological endpoints and stem from the fundamentally different worldviews of their proponents. They are, in themselves, perhaps the most fundamental points of conflict.

The conflict between worldviews is clearly evident in current debates over the viability and desirability of large dams. In South Asia, large dam projects have been designed and implemented by the state and are run through highly centralized irrigation departments. This approach has its roots in Nehruvian socialism with its emphasis on the State as a primary actor and motivator of development. Opponents to such projects often propose community-based management through communities and the revitalization of traditional water management systems. Opposition can also come from organizations, such as the World Bank, that emphasize the dominant role of economics and the private sector. This worldview may not oppose the dams per se but focuses on reducing the role of the public sector in their construction, operation and maintenance. The conflicts generated by the above worldviews can be intense. In Gujarat, for example, debates over the Narmada project and potential alternatives to it have led to withdrawal of the World Bank’s financing for the scheme and to many instances of physical violence between opponents and the State.
Opportunities also often abound in the contested terrain between worldviews. In many cases ideologies can be undermined by rational arguments based on neutral scientific information and data. In the large dam debate, for example, most scientific information has been collected and project proponents have done engineering analysis. Alternatives have rarely been analyzed in a systematic or professional manner – one that would be viewed as technically equivalent to the analyses undertaken for the dam project. Proponents of community-based approaches to water management lack the professional capability and scientific information necessary to establish whether or not the approaches they advocate represent viable alternatives to large state-centric projects. Opponents are, at least in some cases, capable of blocking the implementation of large projects such as the Arun III project in Nepal. They are, however, rarely able to develop comprehensive alternatives. Deadlock results. This type of situation represents a potentially major opportunity in which professionally competent and politically neutral “social auditors” can catalyze change by undertaking high quality analysis of alternatives and engaging the full range of involved stakeholders in dialogue. This is the type of opportunity our collaborative project is designed to exploit.
pollution
In South Asia and many other parts of the world, emerging water problems threaten the viability of entire ecosystems and the sustainability of water supplies for fundamental human needs. The nature of these water problems, however, varies greatly between locations and scales of analysis. Pollution, groundwater level declines, flooding and water logging can all represent significant water management problems even within local administrative areas. High geographic variability is compounded by great seasonal variability. An area may experience severe seasonal water scarcity during the hot season and also have major flooding problems. Many such problems are inherently local in nature; others cannot be addressed without coordinated action at a regional or basin scale.

Social responses to water management needs throughout South Asia have tended to fall into three broad categories:
1. Highly centralized projects undertaken by national and state government.
2. High-level attempts to influence the legal and economic environment in which water use occurs.
3. Village or community level initiatives.
These approaches reflect three underlying models of social change. The first emphasizes the dominant role of formal ‘decision-makers’ within governments and development organizations as the agents through which policies and programs are first formulated and then translated into governmental action. The second downplays the role of national or local organizations and focuses instead on the role of economic incentives, rights, markets and the private sector as the primary mechanisms for allocating water and limiting extraction to sustainable levels. Finally, the third emphasizes the role of individuals and communities as the dominant factor determining water use and management at the local level. These models are, of course, not isolated and the broad stream of literature, research and implementation projects focused on ‘participatory’ approaches and the links between economics and institutions reflects common attempts to integrate them. Our main concern with the models, however, is that none has proved effective in initiating widespread development of effective management systems.
We believe the above failure stems from fundamental misconceptions regarding the manner in which social change occurs. From our perspective – one which is admittedly difficult to prove – social and institutional change emerges from a contested terrain in which many actors (individuals, communities, businesses, NGOs, local government organizations and the State) compete to protect their economic, political, cultural, social and other interests. This competition occurs at multiple levels within the frameworks created by markets, laws and social norms. It often results in deadlock. In some cases, this deadlock is related to inherent conflicts of interest and can only be resolved through the victory of one or another set of stakeholders. In other cases, however, conflicts of interest are not inherent but deadlock occurs because there is no common framework for identifying, understanding or negotiating potential solutions. Innovators and social auditors capable of identifying potential solutions and creating common frameworks for understanding, dialogue and negotiation among stakeholders can play major catalytic roles in this latter type of situation.
pollution
The effects of water pollution are many, here are just a few of them:

· DISEASES:
The diseases that are transfered due to water pollution are mainly caught by seaman and people who live near the water, these diseases include cholera, typhiod fever, and dysentery although it may seem like a list of diseases you catch while playing Oregon Trail, they are serious and people with symptoms should consult a doctor immediately!

· WATER POISONING:
PCB's (polychlorinated biphenyls), chloroform, and pesticides have been found in some municipal drinking water supplies. Sccientists are concerned that drinking even a small quantities of these substances over many years may have harmful affects.

· RECREATIONAL EFFECTS:
Recreational effects that water pollution has prevent people from using and enjoying water due to odors and floating debris, which make boating and swimming unpleasant. And the risk of diseases make polluted water unsafe.

· PROCESS DISTURBANCES:
Processes in water which use the oxygen in water help to make the wastes harmless. In Mineralization aerobic bacteria break down organic wastes into simpler substances. Some of those substances (Phosphates and Nitrates) serve as nutrients (food) for plants. Aerobic bacteria uses oxygen in water when breaking down organic wastes. Scientists can find out how much organic matter the water contains by measuring how much oxygen the bacteria use when breaking it down. If the water contains too much organic wastes, the bacteria will use up most or all of the oxygen in it. Some species of game fish such as salmon, sturgeon, trout, and whitefish will be unable to live in the water. If all the oxygen is used, most aquaticlife will be unable to survive.
