Permeable reactive barriers (PRBs) are considered as an effective remedial option for groundwater contaminated with chlorinated ethens. A pilot-scale PRB installation described in this article has been used to: 1) test the possibility of treating groundwater contaminated with trichloroethylene (TCE) in the vicinity of the water works in SE Poland, and 2) to verify under field conditions the usefulness of compost and brown coal mixtures as the effective PRB reactive material (cheep, easily available and environmentally friendly) previously studied through batch and column tests.

Constantly growing demand of water makes it necessary to search for new perspective areas in terms of gain groundwater. Dębica area is located on the border of two geological units: the Outer Carpathians and the Carpathian Foredeep. Currently, that area suffers from water deficiency, which would have been earmarked for utility purposes. To understand this problem quantitative and qualitative assessment of the groundwater status in two catchements on this area was made. Research in the catchments of Ostra and Zawadka was made on September 2013. For the purpose of estimating the size of quantitative resource of Zawadka and Ostra catchments the method based on information of the recharging infiltration rate was used (Nescieruk et al. 1992, Korzec & Dendys 2014, Mars 2014). Calculation of flow rate was based on measurements of floating object method and volumetric method (Bajkiewicz-Grabowska & Magnuszewski 2002). Furthermore, the depth of the groundwater table was estimated based on measurements performed on the wells located in that area. For qualitative status assessment samples were taken for physico-chemical analysis, which was made by accredited hydrogeochemical laboratory KHiGI AGH UST (Stefańska 2014). Bacteriological analysis was carried out in the sanitary-epidemiological station in Jasło. The results were used to perform water tablemap, define disposable resources (2902.2 m3/d in Zawadka catchement and 4940.3 m3/d in Ostra catchement) and admissible volume of ground-water evaluation (1802.2 m3/d in Zawadka catchement and 4191.9 m3/d in Ostra catchement) (Dendys & Korzec 2014, Mars 2014). Finally, quantitative status of Ostra and Zawadka catchment was classified as good. The results of chemical analysis were compared with the Ministry of Health Regulation about health suitability of water for human consumption. The value of nitrates was up over 100 mg/L (at the permitted 50 mg/L) at Ostra catchenment. Additionally, water cannot be collected, due to exceeded value of the bacterial content of Coliform Group Bacteria and Escherichia coli at Zawadka and Ostra catchement. In summary water is not suitable for drinking (compared with Ministry of Health Regulation – Rozporządzenie...2010).

Nadal dosyć powszechnie wśród mieszkańców wsi panuje przekonanie, że środowisko zanieczyszczane i niszczone jest przez przemysł i obszary zurbanizowane, natomiast wieś i rolnictwo raczej środowisko chronią. Ten stereotyp nie do końca jest prawdziwy - rolnictwo i mieszkańcy wsi w znacznym stopniu przyczyniają się do ogólnego zanieczyszczania środowiska przez naszą cywilizację.
