Watermelon rind, usually discarded as waste, has been shown by researchers in Pakistan to be capable of cheaply and efficiently removing arsenic from groundwater.

NEW DELHI: Noting groundwater contamination in an around the Sterlite Copper plant at Tuticorin in Tamil Nadu, the government on Monday told the Rajya Sabha that the analysis of samples from the un

The vast majority of Europe’s rivers, lakes and estuaries have failed to meet minimum ecological standards for habitat degradation and pollution, according to a damning new report.

GURUGRAM: Environmental activists have suspected it for long, but now, they can place actual figures against their suspicion.

Contamination of groundwater sources due to over-abstraction and discharge of polluting substances has been a long standing problem in most parts of the country. In 1974, a legislation was specifically enacted to regulate and prohibit water pollution.

In middle Gangetic plain, high arsenic concentration is present in water, which causes a significant health risk. Total 48 morphologically distinct arsenite resistant bacteria were isolated from middle Gangetic plain. The minimum inhibitory concentration (MIC) values of arsenite varied widely in the range 1–15 mM of the isolates. On the basis of their MIC, two isolates, AK1 (KY569423) and AK9 (KY569424) were selected.

Hydrogeochemical investigations were carried out in semi-arid region of Basara to estimate the quality of groundwater for its suitability for domestic and agricultural purposes. For this region 34 groundwater samples were collected in different locations and analyzed for various ions, viz., Na+, Ca2+, Mg2+, K+, Cl−, HCO3−, SO42−, CO32−, HCO3−, NO3− and F− to assess the water chemistry with sodium absorption ratio, %Na, residual sodium carbonate, magnesium hazard.

Groundwater quality deterioration due to anthropogenic activities has become a subject of prime concern. The objective of the study was to assess the spatial and temporal variations in groundwater quality and to identify the sources in the western half of the Bengaluru city using multivariate statistical techniques. Water quality index rating was calculated for pre and post monsoon seasons to quantify overall water quality for human consumption. The post-monsoon samples show signs of poor quality in drinking purpose compared to pre-monsoon.
