SEDIMENT QUALITY ASSESSMENT OF AVARAGERE LAKE, DAVANAGERE CITY - A CASE STUDY
Journal Title: International Journal of Innovative Research in Advanced Engineering - Year 2016, Vol 0, Issue 0
Abstract
Avaragere Lake in Davangere was studied for chemical and physical parameters at five locations, for a period of six months (April 2014 to Sep 2014). Lake has been subjected to human interferences regularly and water quality was to be getting deteriorated profoundly. Major anthropogenic activities practiced in and around the stretch: agriculture, discharging of sewage waste etc was generating serious threat to the biota of the lake by altering the physical, chemical and biological concentration of the lake system. The other possibility is that since there are no major industries in the project area, the major source of organic pollutants is only the domestic source. Monthly data’s been collected. Different parameters studied were pH, Conductivity, organic carbon, nitrogen, phosphorus, potassium, zinc, copper, iron, organothiophosphate and pyrethroid content. The results obtained from the above study indicate that the water of Avaragere Lake organothiophosphate and pyrethroid content shows very low concentrations even at nanogram. Manganese and iron concentrations of sediment sample in avaragere lake shows high level of pollution and ecological balance of Lake is totally disturbed.
