Increased incidences of fluoride concentration in groundwater and its impact on human health, was initiated to determine groundwater fluoride concentration in East Imphal District of Manipur.

Groundwater monitoring was carried out in Tarikere taluk during December 2004. The samples were analyzed for trace metals, such as iron, cadmium, lead, copper, zinc, nickel and barium.

Surface and groundwater pollution in the mining and industrial area is a growing concern. Jharia Coalfield is one of the biggest coalfield and highly industrialized area in India. A study was undertaken in some of the coal mining and industrial areas in this coalfield to assess the quality of surface and groundwater.

Tubewells have been so popular in rural Bangladesh that about 12 million have been installed, yielding water that is convenient, free and low in bacteria. But every fourth well is polluted with arsenic, with the result that millions of people are exposed to a severe environmental hazard. We explore this crisis from the viewpoint of legal geographies.

The present work aims to study the level of fluoride in bore well, open well, and in handpump water samples of different places of Virudhunagar district, Tamil Nadu, and also to analyse other water quality parameters, like pH, electrical conductivity, turbidity, acidity, alkalinity, total solids, chlorides, iron, sodium, potassium, fluorides and total hardness.

Ground water samples were collected from 18 wards of Coimbatore city south zone, among which 2 samples were collected from 2 different locations from each ward, totaling 36 samples.

The present study deals with the physico-chemical parameters of ground water quality in Mundargi taluk of Gadag district, Karnataka state, the study has been carried out during September 2003.

Ground and well water samples were collected from Manchankoppu, Tiruchirappalli district. Physical parameters, such as temperature, odour, taste, turbidity, pH and conductivity and chemical parameters and compared with ISI, WHO and USPHS. Sulphate, silicate, phosphate, nitrite and nitrate contents were also analysed.

The quality of ground water samples collected from 7 representatives tubewells in rural areas around Angul-Talcher industrial zone, Orissa was assessed in the rainy, winter and summer from July 2001 to June 2003. A total of 20 physico-chemical characteristics were analysed. Some parameters were found within and some parameters beyond the desirable limit for drinking purpose.

The 26 December 2004 tsunami caused widespread destruction and contamination of coastal aquifers across southern Asia.
