Hydro Chemical Behaviour of Contaminants

Pollution of ground water originate from either as point source or non-point or diffused source. The sources responsible for water quality deterioration are domestic waste, industrial waste and agriculture practices. Pollution of groundwater from agriculture is the diffuse source of pollution and application fertilizers and pesticides coupled with unscientific management of crops, water, soil and fertilizer, are the additional sources responsible for ground water pollution. A good planning along with scientific approach is required for crop pattern and use of chemical fertilizer to check this diffuse source of pollution. Domestic wastes where the contaminants are leached to the groundwater body from landfills, cesspools, septic tanks and composite pits, Industrial wastes where release of untreated wastewater into the streams, nallahs and open lands are the potential threats to the portability of ground water. These wastes falls under point source pollutants category and can be checked. Hydro-chemical behaviour of the various inorganic contaminants including trace metals, due to the point / non-point sources are therefore receive special attention under the pretext of their distribution in groundwater regime.
