///It is found that phreatic water quality in study area is poor. The main component and index exceeding standard Ⅲ rate include（NO₃）^-,total hardness,Fe²⁺,（NO₂）^- and total dissolved solids, followed by Cl^- and（SO₄）^2-. Among which（NO₃）^- exceeds standard Ⅲ rate mainly found in residential areas, agricultural production region and groundwater exploitation region.  In this paper, the authors discussed the reason for this kind of change mainly from ground water exploitation.
