废水由位于Uttrakhand首都的Dheradun工业区收集。

在2010年11月期间收集了样品，从2011年11月到2011年8月确定了以下参数，pH，温度，浊度，化学品氧需求（COD），生物需氧量（BOD），溶解氧（DO），电导率，总溶解固体（TDS），总悬浮固体（TSS），硫酸盐，硝酸盐，亚硝酸盐和磷酸盐。此外，确定金属（铜，钴铬，铁，锰，镁，镍镉，铅，钠，钾和钙。pH，电导率，温度，硝酸盐，亚硝酸盐，硫酸盐，磷酸盐，TSS，TDS，DD。那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.
