Sewage Pollution

  • Pollution in the Mahanadi: Urban sewage, industrial effluents and biomedical waste

    The discharge of municipal sewage, industrial effluents and biomedical waste into the Mahanadi has raised concerns about environmental sustainability and also posed a serious threat to the health of people living on the banks. This article critically examines the river pollution caused by the spiralling urbanisation and industrialisation along with dumping of waste by many medical facilities. There is an urgent need to address this enormous challenge which is a direct outcome of inefficient planning and management.

  • Raking through sludge exposes a stink

    A former US Environmental Protection Agency (EPA) scientist is suing the agency's officials and researchers at the University of Georgia in Athens, alleging that they manufactured and published false data to support the use of potentially harmful sewage sludges as fertilizers. The sludges have been linked to health problems in humans and cattle

  • Stuck in the mud

    Some 30 years ago, as the United States began to tighten its environmental regulations on residential and industrial wastewater, operators of sewage-treatment plants embraced what seemed an eminently sensible idea. They decided to take the rich organic sludge left over after clean water is extracted and sell it to farmers as fertilizer. The programme might well be as sensible as it seems. It is possible that the millions of tonnes of sludge being spread across the rural landscape contain no significant levels of toxic chemicals, heavy metals or disease-causing organisms.

  • Stagnation of sewage, the price for development of Porur

    The price of haphazard development is paid by residents of BHEL Nagar and Amman Nagar, who have endured a persistent water stagnation problem for over 10 years now. Well into the summer, buffaloes find a cool haven in the water and sewage stagnant inside the colony. "The water dries for a few months from June or July. Since the layout of over three acres area was occupied from 1992, residents have had to deal with stagnant water two or three feet deep for six to eight months a year,' said Adhi Narayanan, Secretary, BHEL Nagar and Amman Nagar Association.

  • What we get is contaminated water, say Thoraipakkam residents

    Unsafe for consumption: Samples of contaminated water drawn from well at a house in Sai Nagar in Thoraipakkam. Dumping of garbage in the heart of the Pallikaranai Marshland (Perungudi Dumping Yard in official parlance) and letting out of untreated sewage from different sources into the Buckingham Canal have resulted in an irreversible damage to the quality of sub-surface water in residential localities of the fast developing Thoraipakkam and Perungudi. On a visit to nearly half-a-dozen localities in Thoraipakkam on Monday, presspersons found that water drawn from domestic and deep borewells in Thoraipakkam was orange in colour and accompanied by a pungent, foul smell. Environmentalists fear that the problem is fast heading towards an unprecedented catastrophe in this part of Chennai. Residents complained that quality of water drawn from wells in Sai Nagar, Selva Ganapathy Avenue and Saravanan Nagar, among other adjoining localities, was consistently deteriorating over the past few years. Of late, the residents were forced to depend on water drawn from wells for washing clothes and cleaning utensils. Office-bearers of civic groups in Thoraipakkam attributed the problem to the dumping of garbage and the letting out of raw sewage. Residential areas in Okkiyam Thoraipakkam village panchayat and Perungudi town panchayat were the worst affected, said Periasamy, President, Sai Nagar Residents Welfare Association. At least, a few thousand wells in the areas were contaminated, a few residents of Sai Nagar said. They said while the affluent sections could afford expensive water purifying equipment, the poor were left with little option but to use the contaminated water for household purposes. In the absence of a complete, safe and protected drinking water supply scheme, even economically weaker sections have to purchase bottled water. Owing to the dumping of garbage, leachates seeped into the sub-surface and entered recharge channels through which groundwater entered the domestic and deep borewells. Leachate was caused by the percolation of waste from garbage dumped on landfill sites, said N.Srinivasan, environmentalist. The problem was not restricted to Perungudi or Thoraipakkam, but to far-off places, including Muttukadu, through which the Buckingham Canal meandered . Mr. Srinivasan said a study revealed that fishermen were deprived of their normal catch of fish as a large number of fishes died owing to the sewage content in the Kovalam creek. Mr. Periasamy said the laying of the Pallavaram-Thoraipakkam Radial Road had only made it easier for rural and urban local bodies along Rajiv Gandhi Salai (formerly Old Mamallapuram Road) and East Coast Road to dump solid waste on the fringes of the marshland. Putting an end to dumping and burning of garbage and ensuring the discharge of only completely treated sewage might, to a large extent, help reverse the trend, he added.
