皖江城市带地下水质量与污染评价

利用2012年—2015年皖江城市带地下水污染调查工作所取得的无机测试数据，采用单因子评价法和综合质量评价法进行地下水质量评价，采用无机毒理指标进行了污染评价。地下水无机指标质量综合评价结果显示，皖江城市带可以直接饮用(Ⅰ~Ⅲ类水)或经适当处理可以饮用(Ⅳ类水)的地下水资源占81.7%，不能直接饮用的地下水资源(Ⅴ类水)占18.4%。地下水无机指标污染评价结果显示，未受污染的占34.43%，极重度污染的占13.78%，其余占51.79%。皖江城市带地下水总体来看形势较为严峻，应该尽快组织实施皖江城市带地下水污染防治规划，遏制地下水污染恶化态势，有效保护研究区地下水资源与环境。
