GROUND WATER QUALITY

GROUND WATER QUALITY

Ground water quality comprises the physical, chemical and biological qualities of groundwater. Temperature, turbidity and test make the list of physical water quality parameters. Naturally ground water contains minerals ions. These ions slowly dissolve from soil particles sediments and rocks as the water travels along minerals surfaces in the pores of unsaturated zones. They are refers to as dissolved solids. The total mass of dissolve constituents is as total dissolve solids. A higher total dissolve solid means there more ions in water. Due to more ions waters electrical conductivity increases. At high concentration of total dissolve solid water becomes saline. Water with a TDS (total dissolve solid) above 500mg/l is not recommended for drinking water whereas water with TDS above 1500mg/l is generally considered problematic for irrigation use.

High concentration of metal can be found in ground water near contaminated resources. Some trace constituent that are associated with industrial pollution such as arsenic and chromium may also occur that are high enough to make the water unsuitable as drinking water. They are sometime toxic too.

Microbial document is a natural constituent of ground water but human activities can alter natural composition of ground water through the disposal of chemicals and microbial matter at the land surface and into the soil through injection of waste and directly to the ground water. Such activities of human can be abolished by organizing awareness programme among illiterate mass about the importance of ground water. Disposal of wastes in landfill area similarly proper disposal of chemical or hazardous wastes concentrated constituent may remain in ground water for long time.
