SURFACEWATER CONTAMINATION ASSESSMENT IN INDUSTRIAL PARK MAHAD M.I.D.C. RAIGAD, MAHARASHTRASRIKANT KEKANE AND R.P. CHAVAN
The surface water quality in Mahad M.I.D.C.âs industrial area was analyzed; water from study area is used for domestic purposes, so the quality of surface water must be assessed. A few industries discharge their wastewaters into a nearby nalas and river. Throughout the year, water samples were obtained from nalas and river located across the industrial area at one-month interval. To determine the effect of industrial wastes on surface water, the following parameters were estimated: pH, EC, Na+, K+, Cl-, Ca2+, Mg2+, HCO3-, TH, TA, PO43-, SO42-, and NH3-N. The findings indicate that in the current analysis, the majority of the physicochemical parameters of water samples were below the permissible level of drinking water quality.
