摘要：The electrical conductivity, alkalinity, salinity, hardness and chemical load of the groundwater in urban area of the country are increased enormously due to excessive urban stresses by making water unsafe for drinking purposes. Therefore, the groundwater quality of Raipur city, capital of Chhattisgarh state, India has been investigated. The physico-chemical characteristic of the groundwater along with the chemical loading variations is described. Various indices were used for rating of groundwater quality for drinking and irrigation purposes. The cluster and factor analysis models were used for source apportion of the contaminants.
