Current research on groundwater vulnerability is aimed mainly at groundwater pollution vulnerability (GPV), and the vulnerability of groundwater quantity is seldom considered. It is important to carry out the groundwater vulnerability evaluation for the management of groundwater resources. This paper presents evaluation models and methods for assessing groundwater quantity and pollution vulnerability. The models and methods were used to evaluate the groundwater vulnerability in the plain area of Baotou, Inner Mongolia, China. The groundwater quantity vulnerability was assessed by computing the groundwater recharge rate, and the GPV was evaluated by simulating the migration time for pollutants traveling from ground surface to the aquifer. The research results could provide scientific support for the management of regional groundwater resources, prevention and control of groundwater pollution.

Groundwater is an important component of water resources. Compared with surface water, groundwater has slower flow rate and lower capacity of diluting and self-purification. It is difficult to treat the groundwater pollution. Therefore, it is important to protect the groundwater from being polluted for planning and management of groundwater resources. It is considered as an effective method for decision makers and administrators to identify the high risk level of groundwater pollution through groundwater pollution vulnerability assessment. In this study, the most widely used DRASTIC model and GIS software were used to evaluate the groundwater vulnerability of Chengting new district in Shijiazhuang, china. The groundwater vulnerability grades of the study area were divided by the model. The research results could provide scientific basis for the new district planning and construction.

Continual overdraft of groundwater resources for many years has led to continual declining of groundwater level in large scale areas in Shijiazhuang. Groundwater in Shijiazhuang City has been contaminated in varying degrees during its development and utilization due to no appropriate protective measures taken for groundwater resources. Groundwater pollution is severe in some areas, which poses a threat to sustainable utilization of groundwater resources and economic and social development. To protect groundwater resources effectively, a study on the impacts of general planning implementation on groundwater resources was carried out, including groundwater pollution sources, groundwater quantity and groundwater quality evaluation. The research results could provide scientific reference for development planning and sustainable utilization of groundwater resources of Chengting new district.

Groundwater is widely distributed and stability changed.It is the ideal drinking water with good quality and easy application.As well as, it is an important water supply source of the life, industry and agriculture.However, groundwater pollution can't be ignored in China.In this paper, groundwater pollution,groundwater vulnerability evaluation and groundwater water pollution remediation technologies are reviewed through reading a lot of theses in China and other countries. The groundwater vulnerability evaluation of DRASTIC and based on the GIS technology are mainly introduced. According to the evaluation results, appropriate pollution remediation technologies are taken, so as to protect and repair groundwater. I hope this paper can provide some theoretical suggestions for the sustainable development of groundwater in China.

Pollution Risk

A universal method to evaluate groundwater pollution risk with the site scale has not been established. The groundwater pollution risk is commonly evaluated by overlaying the results of groundwater vulnerability and pollution sources, but this method is inapplicable for contaminated sites. Considering the current supervision demands of groundwater pollution in China, this paper suggests a risk evaluation method for contaminated sites. The present and forecasted groundwater pollutant concentrations and the variation trend of groundwater quality were used to get the risk classes of groundwater pollution. Chromium is one of the most common groundwater contaminants found at industrially contaminated sites. A chromium residue disposal site in Baotou, China was selected as the study area. The groundwater flow model and solute transport model were constructed by MODFLOW and MT3DMS. Based on the simulation results of the numerical model, the groundwater pollution risk of the contaminated site was divided into four classes, and the regulation measures of groundwater pollution were suggested. This study could provide guidance for the environmental supervision and management of contaminated sites.

The people's gold mining and processing activities have an impact on the surrounding environment. Some residents immediately dispose of waste from gold processing into the environment. Therefore, analysis of the level of vulnerability of pollution is needed to determine the size of the level of difficulty and ease of contaminated substances to influence water quality, both surface water and groundwater. The purpose of this study was to analyze the level of vulnerability of groundwater pollution around the study area. The method used in this research is survey method and field mapping, sampling method: purposive sampling, laboratory analysis method, mathematical method, and descriptive evaluation method. The calculation to determine the level of vulnerability of pollution is the DRASTIC method for groundwater vulnerability with 7 parameters, namely groundwater depth, rainfall, aquifer type, soil texture, slope, slope, unsaturated zone type, and hydraulic conductivity. Based on the results of the study it was known that the study area had 2 classifications of the level of vulnerability of groundwater pollution, namely the moderate and high classification. Areas that are located in the direction of groundwater flow and are lower than pollutant sources will potentially be more polluted.   Keywords : DRASTIC, Pollution, Groundwater, Gold Mine

Abstract The Songnen Plain in Northeast China is the only remaining black soil agricultural area in the world and is an important food base for China. The groundwater resources in this area are abundant, but human activities have caused them polluted. This paper established a groundwater vulnerability assessment to characterize the influence of human activities which used an entropy weight method. The index was tested using the nitrate pollution distribution in the groundwater to verify the effectiveness of this method. The results showed that areas with high specific vulnerability were distributed in the northern and eastern parts of the Songnen Plain and were consistent with areas that showed serious nitrate pollution of the groundwater. The correlation coefficient between these areas was 0.2536, which greatly improved the vulnerability assessment without superimposing human activities in the model. The results clearly showed that human activities increased groundwater vulnerability on the Songnen Plain. The evaluation method provided a reference for similar evaluations and a basis for the protection and management of groundwater resources in this region.
