| Research Status of Partial Acid Groundwater in Xingguo County, Jiangxi Province |
| Shallow groundwater is the main source of drinking water in Xingguo towns and villages, the distribution of acid groundwater (pH＜6.5) in the shallow groundwater is 1/2 of the whole area, and regional groundwater acidification is obvious. It has become one of the problems of safe water in the area. In accordance with the uniform deployment of the former Ministry of Land and Resources, China Geological Survey commenced the hydrogeological survey work in Xingguo County of Jiangxi Province in 2017. Based on 768 groups of groundwater on-site water quality tests and 80 groups of related hydrochemical analysis data, the authors studied the distribution characteristics and influencing factors of partial acid groundwater in Xingguo County. The result shows that acidic groundwater with pH < 6.5 is quite common. Acid groundwater is mainly distributed in granite fissure water, the pH value of groundwater is obviously affected by local acid rain, consistent with the acidic soil distribution. It is closely related to the types of water-bearing media. With the increase of water depth, the pH value of groundwater increases. This study is of great importance for correct understanding of the distribution characteristics and influencing factors of partial acidic groundwater, and for promoting safe water use for urban and rural residents as well as preventing acidification pollution of groundwater. |
