Assessment of groundwater quality in Bushehr province using water quality index

Groundwater resources in Bushehr province aquifers are strongly affected by the factors of agricultural wastewater, closeness to sea, high salinity, and lying over oil and gas fields. Therefore, it seems to be important to evaluate groundwater quality in the study area. In this study, 360 water samples from different parts of the province were collected from wells, during 1387-1390. Cations and anions as well as chemical parameters were analyzed. Water Quality Index (WQI) and other effective chemical parameters were calculated. Ground water quality index (GWQI) map in the study area reveals that groundwater quality order is as Jam>Dashtestan>Dashti. Quality of water in Jam meets the highest quality among all and Kangan city has non-suitable drinking water. In general, groundwater quality in Bushehr province do not meet the water quality standards for some quality parameters and therefore it needs to be managed in Bushehr province.
