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.

Groundwater pollution risk is determined both by the intrinsic vulnerability of the aquifer and the existence of potentially polluting activities at the soil surface. This raster has a resolution of 15*15 km. It was generated by combining a groundwater vulnerability model (based on the DRASTIC method) with land use/land cover (from the GlobCoverdatat set) using an additive model.

Risk Assessment Method

The risk assessment model and parameter system of groundwater pollution were established in this paper. The multi-index evaluation method of groundwater pollution sources was proposed, and the GIS-based risk assessment method of groundwater pollution was produced in comprehensive consideration of groundwater vulnerability and groundwater pollution sources. The multi-index method suggested in this paper was used in the risk assessment of groundwater pollution at a plain area of a big city in North China, and the different grades of groundwater pollution risk were computed. The evaluation results show that the groundwater pollution risk is determined by the combined action of ground pollution sources and groundwater vulnerability. The established risk assessment method of groundwater pollution could give a scientific support for the regional groundwater pollution prevention and control planning.

AbstractGroundwater vulnerability assessment has become a crucial step in successfully protecting groundwater against pollution. An attempt of this study has been made to evaluate groundwater contamination risk using intrinsic vulnerability and land-uses in Vanathavillu, Kalpitiya and Katana area in Sri Lanka, using coupled DRASTIC with GIS as feasible methodology. The findings reveal that the groundwater in the areas under study falls under very low to high contamination risk. The higher risk of contamination has been identified in most of the Kalpitiya (about 82%) with the moderate along the beach in the west and next to Puttalam lagoon in the northeast and southeast. This is mainly due to pollution risk inherent with intense vegetable cultivation, over pumping, shallow groundwater tables and permeable sandy soil. Vanathavillu is under very low to moderate contamination risk, in which the moderate risk (about 13%) has especially been found the center, central southwest and west of the area. The relative less deep groundwater tables, possible seepage from the underlying limestone aquifer and less permeable red earth soil could be cause for the moderate risk in the area. Furthermore, results show that the Katana has low to moderately high groundwater contamination risk. Nitrate has a good agreement with the different pollution risk classes and that nitrate can be used as an indicator of aquifer degradation inherent with land-use activities in the coastal areas. Groundwater quality monitoring network should be set up to minimize the anthropogenic acts, particularly in high and moderate contamination risk zones.

Analysis has studied northern part of Jahorina, Ravna Mountain, whose karst plateau presents wateraggregation surface for Paljanska Miljacka and Bistrica flows, which are used as water supply forSarajevo and Pale. This paper presented hydrogeological and hydrological characteristics of the areaand applied analyzes of other physical-geographic characteristics which are an essential indicator of thequality of groundwater. Applying various methods, we have obtained maps that shows different waysof groundwater pollution in karst. We analyzed spatial relationships and connections with individualsocio-geographical components. Thought correlation methods we obtained results which providedconclusions for possible measures against pollution of groundwater in karst and karst in general.
