新乡粮食核心区地下水水质评价

Evaluation of Groundwater Quality in Xinxiang Grain Core Area

根据2011年新乡地区93组地下水水质样品分析成果,采用不同的评价标准,对新乡地区地下水水质现状进行了评价。评价结果表明:区内浅层地下水多为水质较差的Ⅳ级水,中深层地下水多为水质良好的Ⅱ级水。评价区浅层地下水已受到较普遍的污染,水质较差,亟待改善。提出在水质恢复区严禁混合开采。避免串通污染,要加大地下水污染监测工作,禁止污水灌溉,对污染严重的化工、造纸等企业应要求零排放。

According to the analysis results of groundwater quality samples of 93 groups in Xinxiang area in 2011, the evaluation status of groundwater quality in Xinxiang area was evaluated by different evaluation criteria. The results show that the shallow groundwater in the area is mostly grade IV water with poor water quality, and the middle and deep groundwater is mostly grade II water with good water quality. Shallow groundwater in the evaluation area has been more commonly polluted, poor water quality, urgent improvement. Proposed in the water quality recovery area is strictly prohibited mixed mining. To avoid collusion pollution, to increase the groundwater pollution monitoring work, to prohibit sewage irrigation, pollution of the chemical industry, paper and other enterprises should require zero emissions.
