Abstract

Industrial activity is one of the major reason of groundwater contamination. Arsenic is one, which is responsible for the contamination of the groundwater. Its testing in groundwater is considered as an important activity due to its serious effects on human health. Arsenic problem in Pakistan has been identified recently as a result of field testing. In Faisalabad, arsenic has been found in groundwater within permissible limit. But due to increasing industrial activities the concentration of arsenic is increasing day by day. Drain passing through the city is one of the sources of arsenic in groundwater. The research work was conducted at Syedabbad, Faisalabad. Samples were taken from the selected drain portion and from the groundwater by the help of water pumps. The sampling points were drawn on GIS map by the help of GPS receiver to study the spatial variability of arsenic contamination The results shows that there 10109.9 mg per second intake of arsenic due to drain. Results show that there is no temporal variability of arsenic within the research period but they have spatial variability.

利用gi研究地下水中砷的时空变化特征

工业活动是地下水污染的主要原因之一。砷是造成地下水污染的原因之一。由于其对人类健康的严重影响，在地下水中对其进行检测被认为是一项重要的活动。巴基斯坦的砷问题最近在实地测试后得到确认。在费萨拉巴德，地下水中的砷含量在允许范围内。但由于工业活动的增加，砷的浓度日益增加。流经城市的排水管道是地下水中砷的来源之一。研究工作是在费萨拉巴德的Syedabbad进行的。在水泵的帮助下，从选定的排水部分和地下水中取样。利用GPS接收机将采样点绘制在GIS地图上，研究砷污染的空间变异性。结果表明，该地区因排水而导致的砷摄入量为10109.9 mg / s。结果表明，研究期内砷含量不存在时间变异性，但存在空间变异性。
