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
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.
Even as the Bharatiya Janata Party has expressed displeasure about the manner in which the Pune Municipal Corporation (PMC) has undertaken sewerage treatment for the rivers in the city, the latter has sought fresh funds under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) for continuing the work. The civic administration is also readying a plan to address the sewerage treatment demands up to 2015. The BJP leadership is not amused, saying that PMC should address present day issues before gazing into the future.
A range of treatment is required to remove hazardous contaminants in wastewater before discharge. The article explains the measurements of the main parameters required in order to operate plants efficiently.
THE Corporation of Tiruchy is planning to set up a modern sewage treatment plant as part of the underground drainage (UGD) project within the city. The Tiruchy-Srirangam UGD project, along with the earlier one which is already functioning, is nearing completion. A third phase is also being drafted to accommodate the areas not covered under the earlier two phases. Meanwhile, the first phase is getting a new treatment plant in Panjappur with three pools and the cleaning process is under implementation.
The work on the 100-million-litre-a-day (MLD) seawater desalination plant at Minjur, on the northern outskirts of Chennai, is progressing expeditiously, Local Administration Minister M. K. Stalin informed the Assembly on Tuesday. Initiating the debate on the demand for grants to his department, he said the work would be completed this year. ILF-Mantech, an independent consultant, was appointed to monitor the work.

In this modern world of advanced techniques, sewage treatment works are considered to be one of the most popular procedures carried out to use the treated wastewater for agricultural purposes or to dispose off on to the land. The primary objective of this study is to design a Sewage Treatment System for Sri Satya Sai Urban Development Authority (SUDA) in Andhra Pradesh and studying the possibilities for usage of treated wastewater for irrigation. The study area, Puttaparthy being a pilgrim center attracts people all over the world and during some special occasions the place gets over crowded.
In the present study, an attempt has been made to evaluate the treatability of a combined tannery and domestic wastewater using lab-scale activated sludge reactor under extended aeration.
Human activities have significantly intensified natural phosphorus cycles, which has resulted in some serious environmental problems that modern societies face today. This article attempts to quantify the global phosphorus flows associated with present day mining, farming, animal feeding, and household consumption. Various physical characteristics of the related phosphorus fluxes as well as their environmental impacts in different economies, including the United States, European countries, and China, are examined.
