摘要：Sagardari union is facing groundwater crisis because of contaminations from agriculture and urban sewage,which bring a considerable change in water quality.In view of this,hydro-chemical analyses were undertaken on 35 groundwater samples and the following hydro-geochemical parameters,pH,total dissolved solids(TDS),total hardness(TH),electrical conductivity(EC),cations and anions,were analyzed.From the analytical results,it is found that pH value was lower than WHO drinking water standard and the middledownstream portions of the investigation region show higher EC.The piper plot indicates that the groundwater in Sagardari falls in the categories of NaClHCO3 hydro-chemical facies.Higher TH in groundwater was detected,but still in an acceptable range.In addition,salinity and arsenic ratio are higher and moderately higher,respectively.The spatial distribution of Groundwater Quality Index(GWQI)was determined by geo-statistical modelling of Sagardari union.The study provides information and supports the administration which to make better groundwater utilization and quality control in the Sagardari union.
