Abstract

In recent years, rural drinking water safety has become a growing concern in China. The present study aims to the core problems in rural drinking water safety in Mingshan County, Ya’an, China where groundwater is used as drinking water. The objective of this study was to determine groundwater quality and to assess the health risk of pollution in groundwater in Mingshan County, Ya’an, China. Over the 19-year period from 1991 to 2010, the total number of groundwater samples was 47.This study inspected source water quality, applied the health risk assessment model recommended by U.S.EPA, and calculated carcinogenic risk, non-carcinogenic risk and total risk of factors exceeding standards. Health risk thematic maps of carcinogenic risk and non-carcinogenic risk caused by single factor and their combination can be obtained with the method of inverse-distance weighting interpolation (IDW) and the function of geo-statistical analysis in ArcGIS (Geographic Information System, GIS). The results showed, carcinogenic risk caused by chemicals in drinking groundwater is low, which is in the acceptable interval in risk management both at home and abroad for years. However, non-carcinogenic risk is high and number of sampling sites with risk values exceeding the standards amounted to 30, in which, non-carcinogenic risk of Cr (6+), nitrate, fluoride and Fe of number 43, 46, 74, 64, 67, 50 were the sources that cause total health risk high. This study revealed the risk level of drinking groundwater quality, orders of treatment on pollutants and provided a scientific basis for groundwater management in this area.
