The paper presents characteristics of a small retention dam reservoir Nowaki on the Korzkiew River, in Opolskie Voivodeship. The Nowaki reservoir is one of 9 small retention dam reservoirs operating in the Opolskie Voivodeship. The reservoir functions were described and some remarks concerning operational problems were presented. Particular attention was paid to the quality of water in the reservoir. Preliminary results of the analyses of the quality of water flowing into the reservoir, outflowing and water stored in the reservoir were discussed. The measurements were carried out in 2008. The performed water quality analyses showed that due to N-NO3 -, N-NH4 +, water temperature, pH, electrolytic conductivity the waters did not exceed the limit values defined for class I. As far as total suspended solids are concerned the exceedence of limit values defined for class II was recorded. It was also observed that the water from the Nowaki reservoir was not euthrophic and sensitive to such pollutants as nitrogen compounds from agricultural sources. The analyses of water from the reservoir showed that among the investigated water quality indicators the most unfavorable conditions for the existence of fish were caused by nitrites and total suspended solids, the values of which exceeded the values defined for fish. Due to the values of total suspended solids the quality of the analyzed water does not meet the requirements defined for water used in inland water basins, either. It was concluded that for the efficient use of the Nowaki reservoir proper agricultural and water-sewage management in the reservoir catchment should be ensured. The paper shows that the present technical state of the reservoir is faultless. The final conclusion is that water quality analyses and hydrological and meteorological measurements in the Korzkiew catchment and the Nowaki reservoir should be continued. This could contribute to the improvement of water management and reduction of unfavorable effects of hydro-meteorological phenomena and potential water pollution. Source

The paper reports on the changes in the concentrations of heavy metals (Zn, Pb, Cu, Ni, Cr, Cd, Mn, Fe) measured in the bottom sediments of the river Klodnica in 2004 and 2006. The study has produced the following findings. According to the LAWA classification, the values of the nickel and chromium content determined in the bottom sediments did not exceed the values measured in the geochemical background. The concentrations of lead, copper and zinc were indicative of moderate contamination, whereas the concentration of cadmium showed that the bottom sediments of the Klodnica were severely contaminated. The rise observed in the iron and manganese content of the bottom sediments was associated with the wastewater discharge from coal mines. This finding indicates that the problem of reducing the impact of mining operations on the quality of the river water has taken on a sense of urgency. In 2006, the cadmium content measured in the bottom sediments was higher than in 2004, which suggests an increased accumulation of this metal in the organisms of plants and animals. The results of the study make it clear that heavy metal concentrations in the bottom sediments of the Klodnica river should be monitored on a regular basis. Source

Cellular ATP (cATP) content allows estimation of total number of microorganisms present in water. The information thus obtained enables determination of influence of water treatment processes and biofilm growing on the pipe walls on microbial contamination of pipeline water. Three small water supply systems located in North-Western Poland (efficiency ranging from 80 to 500 m3/d) were selected for research. Physicochemical and microbiological water quality indicator values, the latter obtained with culture methods, complied with current standards. However, results of cATP content determination in water samples did not lead to such unambiguous conclusions. According to water purity classification by the ATP test manufacturer, none of the water samples from the three water supply systems tested complied with 'good' water quality standards; part of the samples was classified as poor quality water. cATP content analysis demonstrated that filtration process in the water stations tested should be verified and special care should be taken at primary filtrate discharge to sewage system. Most likely, these are decisive factors contributing to the biofilm formation on the pipe walls and secondary water contamination. Source

Most of used mineral and organic sorbents are hazardous waste and, therefore, in accordance with actual law regulations must be converted thermally or deposited in the special landfill for hazardous waste. Up to now both methods are expensive and burning methods are still watch as a controversial method. The optimal solution would be sorption materials that could be used repeatedly, without the need for costly and cumbersome lanfilling. Sorbents, which due to their properties could be used repeatedly, are MSW composts generated from mixed or only organic municipal waste. In this study we have investigated the rate of degradation of motor oil on MSW waste composts from two different technologies. Comparison of degradation efficiency, was calculated in comparison to the commercial sorbents. As sorbents were used organic (Peatsorb) and mineral (EcoDryPlus) materials which are in common use and available on the market. Both commercial sorbents were different in case of pH value and amount of biogenic elements and organic matter. Composts used in experiment also were characterized with high EC value, what could be a factor of microbial activity inhibition. During the experiment the total amount of standard diesel oil available on every petrol station and individual n-alkanes with carbon chain length from C8 to C19 was determinate. For comparison additionally was determined content of C20 and C21 n-alkanes. During the experiment, there were observed more intensive oil degradation processes on waste composts in comparison to commercial sorbents. Microflora which use nalkanes as a carbon source, ensured quick (noted after 22 days of the experiment), reduction of the amount of hydrocarbons contamination in the samples, and thus the possibility of re-use of compost as a sorbent. The observed rapid degradation process, indicates the direction of the recovery of compost waste, used previously as a sorbent for the removal of petroleum contaminants (diesel oil). Undoubtedly, this is a cheaper way than the thermal incineration or storage. Source

The paper discusses potential use of changes in load of suspended solids and co-transported trace metal ions to define sectors of the river where increased sedimentation occurs as river bottom deposits. Therefore, flow rate of the river was being determined as well as content of total suspended solids and of selected metal ions (Zn, Cd, Cu, Mn, Pb, Cr, Ni, Fe) in suspended solids and bottom sediments. Changes in the load of suspended solids and of metals with suspended solids found along the course of the river (Klodnica, Upper Silesia) were estimated. It was established that under similar hydraulic conditions the load of metals associated with suspended solids was a function of change in the load of suspended matter. The results of the research allowed determination of sectors of the Klodnica River where sedimentation of the major part of suspended solids is observed and where the number of metal ions in the bottom sediments is increased. This will enable defining sectors of small and medium-sized rivers that require certain measures to be taken in order to improve their ecological state. Source
