镇江市区地下水资源允许年开采量１１ ６８１．９万ｍ~３，１９９９年实际开采量１５７万ｍ~３，占允许开采量的１．３％。１９８６～１９９９年地下水水质资料表明，地下水水质良好，未受重金属和有机物污染；影响口感的指标浓度都在标准以内；水中含适量的微量元素；ｐＨ、硬度、溶解性总固体等指标接近健康水标准。总体评价地下水资源开发基本合理，保护良好。但调查也揭示水质细菌总数、总大肠菌群超标率分别为１８．１％和９．０％，应进一步加强地下水资源保护，以供战备和应急之用。
The annual exploitation of groundwater in Zhenjiang City is allowed to be 116.819 million m ~ 3. In 1999, the actual exploitation was 157 million m ~ 3, accounting for 1.3% of the allowable exploitation. The groundwater quality data from 1986 to 1999 showed that the quality of groundwater was good and that it was not contaminated by heavy metals and organic pollutants. The indexes affecting the taste were all within the standard. The water contained trace elements. The indicators such as pH, hardness and total dissolved solids approached healthy water standard. Overall evaluation Groundwater resources development is reasonable and well protected. However, the survey also revealed that the total number of waterborne bacteria and total coliform bacteria exceeded 18.1% and 9.0%, respectively. Groundwater resources should be further protected for combat readiness and emergency purposes.
