【摘要】 目的调查被洪水淹没的程家岗垃圾场对松花江哈尔滨市水源地水源水水质的影响。方法同步采集松花江各断面（包括水源地）江水和垃圾场浸泡水，按照国家标准方法分别检测了２１项污染指标。结果　有１０项超过国家地面水Ⅲ类水体标准，其中反映有机污染指标的超标情况分别为氨氮、挥发酚、溶解氧、硝酸盐氮；金属类污染指标有总汞、总铁、总锰；细菌学指标细菌总数和大肠菌群也超过相应标准。污染特征主要为有机物污染、金属以及生物性污染等。结论　垃圾场污水较松花江水严重；说明松花江水已经受到垃圾场污水的污染；到采样监测时尚未明显影响水源地水质。更多还原

【Abstract】 Objective To survey the effect of the flooded dump, Chengjiagang dump, on the water quality in the Songhua river, which is the source of water supply of Harbin city.
