The quality of groundwater has been degrading due to municipal sewage, industrial pollutants, fertilizers, herbicides, and pesticides. These dangerous pollutants enter into the deeper soil layers, infiltrate some aquifers, and decrease the gradation of groundwater. Other problems are associated with the leakage of sewer, faulty septic tank cleaning, landfill leachates, throwing of garbage into the river, pond and soil pollution. In coastal areas, salt water intrudes into fresh-water aquifers due to intensive pumping of fresh groundwater. In the present study, the city Kashipur in the state of Uttarakhand has been chosen due to big industrial settlements. The industrial wastes contain many highly harmful elements which destroy the quality of groundwater in the adjacent areas. Therefore, it is our target to test the groundwater quality of Kashipur industrial areas. To analyze the groundwater and to assess the impact of groundwater pollution of Kashipur area, an attempt has been made in the present study to test the physicochemical parameters including pH, total hardness, alkalinity, chloride, fluoride, sulphate, iron, zinc, copper and heavy metal atoms such as lead, arsenic etc. Imbalance of these parameters may degrade the quality of groundwater and may be deleterious to the health of individual and society in context of drinking, agriculture and industrial purposes. Physiochemical treatment of groundwater samples collected in summer, rainy season and post-monsoon were compared and analyzed by regression modeling making a quantitative correlation between pH and other parameters including total hardness, alkalinity, chloride, sulfate, fluoride and copper using multiple linear regression methods.

Kashipur（北阿坎德邦）工业区地下水水质的物理化学评估

由于城市污水，工业污染物，肥料，除草剂和杀虫剂，地下水的质量一直在下降。这些危险污染物进入更深的土壤层，渗入一些含水层，并降低了地下水的水位。其他问题还涉及下水道的泄漏，化粪池清洁不当，垃圾渗滤液，垃圾倒入河，池塘和土壤污染。在沿海地区，由于大量抽取新鲜地下水，盐水侵入了淡水含水层。在本研究中，由于大型工业区，选择了北阿坎德邦州的Kashipur市。工业废料中含有许多极有害的元素，会破坏邻近地区的地下水质量。因此，测试Kashipur工业区的地下水水质是我们的目标。为了分析Kashipur地区的地下水并评估地下水污染的影响，本研究已尝试测试物理化学参数，包括pH，总硬度，碱度，氯化物，氟化物，硫酸盐，铁，锌，铜和这些参数的不平衡可能会降低地下水的质量，并可能对饮酒，农业和工业用途的个人和社会健康产生不利影响。通过回归模型比较和分析了在夏季，雨季和季风后采集的地下水样品的理化处理，并在pH和其他参数（包括总硬度，碱度，氯化物，
