Each plant has been delivering more than 3,000 liters of arsenic and iron-free water daily to the rural community. The first community water treatment plant based on SAR technology was set up at Kashimpore near Kolkata in 2004 by a team of European and Indian engineers led by Bhaskar Sen Gupta of Queen's University Belfast for TiPOT.

Examine the water quality aspects of urban runoff, and a comparison of results across various urban sites; Assess the impact of urban runoff on overall water quality; Implement stormwater management best practices. [1]: iii A major component of the project was an analysis of water samples collected during 2,300 storms in 28 major metropolitan ...
A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
Water research during the late 1970s and 1980s indicated that stormwater runoff was a significant cause of water quality impairment in many parts of the US. [25] Research on stormwater pollution continues in the 21st century, with findings that urban runoff is an ongoing source of water quality problems nationwide.
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
The Post article lead WASA to hand out over 30,000 free water filters, hire health experts, and offer free blood tests to residents. [1] Some water fountains were turned off due to lead levels. [1] In 2004, the D.C. Council held 11 oversight hearings on the issue; the US Congress held four. [1]
Nonpoint sources are the most significant single source of water pollution in the United States, accounting for almost half of all water pollution, [1] and agricultural runoff is the single largest source of nonpoint source water pollution. [2] This water pollution has a number of detrimental effects on human health and the environment.
Below a few centimeters from the surface the interstitial water (water between sediment) is oxygen free. Anoxia is further influenced by biochemical oxygen demand (BOD), which is the amount of oxygen used by marine organisms in the process of breaking down organic matter.
