Opis:: The main aim of the paper was to formulate a proposal of using the draining barriers as a method of limiting pollutants in the groundwater reservoir. Primary processes of pollutants migration and examples of functioning the draining barriers work against the spread of various pollutants in the groundwater were indicated. An untypical kind of draining barrier, i.e. wells which were designed as a hydrogeological borehole to exhaust water intended for consumption, was selected as the research object. For analytical purposes, the available archival results of the physicochemical analysis of groundwater exhausted from the wells, located in the water intake so-called “belt D” in Kraków-Nowa Huta were used. The database was analysed by specialist programs, and the dispersion migration of pollutants from the existing metallurgical waste dump “Ruszcza” in time was presented. Temporary and spatial variability of the physicochemical parameters of groundwater was done during the analysis. The analysis was performed both in the draining barriers wells and in the intake boreholes. A geostatistical analysis of the variability of pollutant spread in the groundwater medium was a vital factor in the appraisal efficiency of the draining barriers operation. It was shown that the highest contents of the researched substances were present in the wells, which are located the nearest of metallurgical waste dump “Ruszcza” and are thereby the wells co-forming draining barriers. The efficiency of draining barriers was found after a thorough analysis.

Opis:: Among nutrients and pesticides, agricultural draining ditches also transport pollutants discharged with untreated wastewater from the municipalities adjoining the ditch. When the ditch water is used for irrigation and aquaculture, risks for the environment and food production are suggested. For the conducted field study, a shrimp farm in Sinaloa (Mexico) was used to trace organic pollutants (pesticides and pharmaceutical residues) on their way from an agricultural draining ditch to a shrimp farm fed partially by the drain water. The concentrations of pollutants in the drain water ranged from 10 ng L-1 to 453 ng L-1. The pond water of the shrimp farm contained concentrations between <10 ng L-1 and 177 ng L-1. The shrimps were contaminated by pollutants at concentrations between 40 μg kg-1 d.w. (dry weight) to 3.3 mg kg-1 d.w. (fungicide Metalaxyl). Health risks for the cultivated shrimps cannot be excluded because some pesticides are known for their toxic effects to crustaceans. The concentrations of selected antibiotics in the shrimps were low and comparable with those found in the shrimps declared as seawater shrimps from a German supermarket. The incorporation of the antibiotics was probably caused by contact to the wastewater in the shrimp ponds and/or by contaminated shrimp feed. Additionally to the anthropogenic chemicals, coliforms were determined in the water (total coliforms: 30-50 CFU 100 mL-1; fecal coliforms: 0-20 CFU 100 mL-1). These values agree with the Mexican Norm NOM-242-SSA1-2009 representing a microbiological quality of water adequate for aquaculture. The number of coliforms measured in shrimp was higher than in pond water, suggesting bioaccumulation and a potential health risk for consumers.
