ABSTRACT
The article describes the point sources of water pollution in Trebisov region. Based on selected indicators of pollution produced and consequently the disposal of waste water treatment efficiency the interaction on the quality of recipients is quantified. The assessment of the impact of point sources of water pollution is based on applicable laws and regulations which set the residual pollution in discharges directly into water bodies. The water quality in the recipients is generally affected by natural and anthropogenic sources of pollution. Clearly measurable and quantifiable are the point sources of pollution, which are under government regulations not only monitored but also charged. In such cases the impact on the basis of regular measurements of quantitative and qualitative indicators on outputs from wastewater treatment plants (WWTP) prior to discharge to the appropriate recipient is clearly demonstrable. Diffuse sources are also contributing to the deterioration of recipients, but indirectly, i.e. it is directly not possible to identify the producer of discharged wastewater to determine the change in water quality in the recipient. From the above, respecting the legislative environment of water management, it is clear that one of the universal principles of environmental policy "the one who pollutes, pays", can be realised only in the case of point sources of pollution, including, in particular, the WWTP that have to treat the wastewater to the limits of the quality indicators that are set in the Slovak Republic by District Environmental Offices with regard to the development of water quality in the respective recipient. The produced wastewater flowing into the WWTP and the cleaning efficiency directly determine the water quality in the recipient. In Trebisov region all point sources of the pollution of recipients into which astewater is discharged comply with limits of all the monitored indicators of pollution in the monitored period. This fact contributes to reduction of negative impacts not only on the quality of surface water but also the interaction with other components of the environment and the overall environmental quality of the region and the health of the population.
