Assessment of antipollution capacity of shallow groundwater in Luanhe Delta

Assessment of antipollution capacity is an important way for groundwater protection. The paper selected shallow groundwater in Luanhe Delta as study object, based on the factors analysis which influenced antipollution capacity of aquifer, combined with hydrogeological condition in Luanhe Delta and established the index system and evaluation criterion that could assess the antipollution capacity of shallow groundwater in Luanhe Delta. The performance was evaluated based on GIS, and the results showed that the weakest district of antipollution capacity were located in the top of alluvial fan with large recharge modulus, coarse lithology of unsaturated zone and high permeability. The results can provide a reference to management, protection and planning of groundwater resource.
