摘要
南通地区浅层地下水分布广泛,水质较复杂,本次对评价区22个深度小于10 m潜水井和20个井深er三线图,并对矿化度、总硬度、氯离子、重碳酸根离子、pH等特征进行评价,综合分析显示南通地区潜水水质较差,10 m以浅潜水质优于10~30 m潜水水质。
Shallow groundwater in Nantong area is widely distributed and its water quality is relatively complex.In this study,sampling and analysis were carried out for the groundwater of 22 submersible Wells with a depth of less than 10 m and 20 submersible Wells with a depth of 30 m(10~30 m filter) in the evaluation area.The shallow groundwater in the investigation area was classified according to Shu card Lev classification method,Piper trigram was drawn,and the total salinity hardness of chlorine ion was calculated The comprehensive analysis shows that the diving water quality in Nantong area is poor.The diving water quality of 10 m shallow diving is better than that of 10-30 m shallow diving.
