Physicochemical Determination of Pollutants in Wastewater in Dheradun

Wastewater was collected from the Dheradun industrial area situated in capital of uttrakhand. Samples were collected between the periods of November 2010 to Aug.2011 determine the following parameters, pH, temperature, turbidity, chemical oxygen demand (COD), Biological oxygen demand(BOD), dissolved oxygen (DO), conductivity, total dissolved solid (TDS), total suspended solid (TSS), sulphate, nitrate, nitrite and phosphate. In addition, metals (copper, cobalt Chromium, iron, manganese, magnesium, nickel cadmium, lead, sodium, potassium and calcium were determined. Levels of pH, conductivity, temperature, nitrate, nitrite, sulphate ,phosphate, TSS, TDS, DO, BOD and COD were higher than the maximum permissible limits set by Bureo of Indian Standard Delhi. The concentrations of the metals in the wastewater were higher limits set by W.H.O. and the maximum contaminant levels (MCL Thus, the wastewater around the Dheradun industrial highly polluted. Domestic and industrial waste should be properly disposed and or recycled. Relevant agencies should make continuous effort to control, regulate and educate populace on indiscriminate waste disposal from domestic and industries within the study area.
