    Trichloroethylene (TCE) and tetrachloroethylene (PCE) are common groundwater organic contaminants that persist in the environment. They have entered soil-water systems because of common use without proper handling for degreasing of metal parts, and currently pose risk for groundwater resources. The author has focused on the groundwater resources contaminated with TCE and PCE related to the waterworks in Nowa Deba where this problem has been identified. The site has been extensively described including the hydrogeological conditions and characteristics of groundwater chemical status. A brief discussion on relevant remediation methods for groundwater contaminated with organic compounds (including chlorinated ethens) has also been provided. Finally, a pilot - scale installation has been designed and is currently tested to demonstrate the feasibility of using permeable reactive barriers (PRB) to treat groundwater contaminated with TCE and PCE. The effectiveness of a mixture of compost and brown coal as the active materials (not expensive, easily available and environmental friendly) is also tested.

    Since the EU Water Framework Directive entered into the polish legal system, the new problem considering over normative presence of trichloroethylene and tetrachloroethylene in the groundwater environment has been noticed. This paper presents evaluation of risks related to groundwater exploited by the water intake in Nowa Dęba with regard to those particular compounds. The main problem concerning the pollution present at the indirect protection area of the water intake has been explored along with its description and layout. In addition, this paper determines the migration times of the compounds from the pollution centre to the receptor i.e. the water intake, it provides quality analysis with respect to the TCE and the PCE index, as well as assessment of the pollution impact on the groundwater quality, characteristic of water treatment practices together with the recommendations regarding correction works leading to environmental remediation of the polluted groundwater environment.
