INTRINSIC AND SPECIFIC VULNERABILITY OF GROUNDWATER TO CONTAMINATION IN A RIVER VALLEYAbstract. The research of groundwater vulnerability to contamination has been conducted in the area of Kampinoski National Park (KNP) and its buffer zone. The assessment of the intrinsic vulnerability has been carried out using a method of DRASTIC while to assess the specific vulnerability an extended formula of DRASTIC has been used. The extended formula considers the potential risks associated with land development and an indicator quantifying the groundwater potential risk of nitrate. The study area is characterized by medium-high (51% of the area) and average (37% of the area) of intrinsic vulnerability to contamination. Other classes of vulnerability occur on a much smaller area. The assessment of specific vulnerability indicates that on the study area, after taking into account the potential risk of groundwater associated with land development, there is mainly medium-high (66% of the area) and medium (33% of area) vulnerability, however after taking into account an indicator quantifying the groundwater potential risk of nitrate, the vulnerability is low (68% of the area) and medium (22% of the area).
