摘　　要：本文应用污染指数法,对北方某经济开发区及周边地下水水质进行了污染评价,结果表明研究区地下水水质以轻污染和中污染为主,局部地区出现较重污染,主要指标为硝酸盐氮、三氯甲烷和三氯乙烯。通过对工业废水、再生水、河水水质的检测,发现研究区地表水水质与污水处理厂再生水排放密切相关,地下水污染很可能与开发区企业排污有关。由于开发区所处位置的环境敏感性和脆弱性,建议今后在开发区及附近继续开展相关研究,进一步查明地下水的硝酸盐氮及有机污染物来源、污染途径,建立完善的监测体系,以便及时切断污染源,保障城市及当地供水安全。In this paper, the groundwater pollution assessment around an economic development zone in Northern China, was evaluated by the pollution index method. The results show that the groundwater quality in the study area is mainly light pollution and mid moderate pollution, only local area is more serious pollution, and the main pollutant is nitrate nitrogen, chloroform and trichloroethylene. Through the detection of industrial waste water, reclaimed water and river water quality, the surface water quality of the study area is closely related to the discharge of the reclaimed water in the sewage treatment plant, and groundwater pollution is likely to be related to the development of enterprises in the development zone. Due to the environmental sensitivity and vulnerability of the zone's location, it is suggested to implement relevant research within the zone and surroundings from now on,while identifying the source and approach of nitrate nitrogen and organic pollutant in the groundwater further and establishing the sound monitoring system, in order to cut off the sources of pollution, protecting the local water supplied safely.
