Water quality of the Bhagirathi, Ganga in the Himalayan region: A study by NEERI
This study of the water quality of the Ganga was commissioned after the construction of the Tehri Dam. It acknowledges that most people in India have a belief that water from the Ganga has bactericidal properties and this might be affected by the dam. National Environmental Engineering Research Institute (NEERI) was retained by the Tehri Hydro Development Corporation Limited (THDC) to investigate any impact that the Tehri Dam might have on the water quality of the Ganga. This report presents the results of that investigation.

Privatisation of urban water supply in Khandwa, Madhya Pradesh - An update from Manthan Adyayan Kendra
Khandwa is a medium-sized town located in western Madhya Pradesh. The 'Khandwa water supply augmentation project' has been awarded to Vishwa Utilities Pvt. Ltd., a Hyderabad based company under the Urban Infrastructure Development Scheme for Small and Medium Towns (UIDSSMT) on a Public-Private Partnership (PPP) basis for water supply augmentation to the town, for the next 25 years. The project has been under execution since October 2009. The private party would supply water to the town @ Rs 11.95 per KL. The raw water for this would be pumped from a reservoir 51 km, away from the town. This report by Gaurav Dwivedi and Rehmat, Manthan Adhyayan Kendra deals with the privatisation of urban water supply in the town.

Effects of industrial and agricultural activities on properties of groundwater - A paper published in the Bulletin of Environment, Pharmacology & Life Sciences
This paper published in the journal Bulletin of Environment, Pharmacology & Life Sciences describes the findings of a study that was carried out to check the effects of industrial and agricultural activities on the groundwater properties in terms of heavy metal concentration. Polluted groundwater is defined as groundwater that has higher concentrations of dissolved or suspended elements than the maximum permissible concentrations fixed by national or international standards for drinking, industrial or agricultural purposes. Sometimes natural groundwater pollution may also occur because of the presence of the respective substances above the prescribed limits.

The main sources of groundwater contamination are industrial, municipal and agricultural wastes (both solid and liquid), rocks, sludge and slimes, refuse, pesticides, herbicides, effluents from livestock and poultry farms. Many pollutants are even able to penetrate into groundwater aquifers.
