Hauled liquid waste as a pollutant of soils and waters in Poland
Journal Title: Annals of Warsaw University of Life Sciences – SGGW. Land Reclamation - Year 2016, Vol 48, Issue 2
Abstract
Improperly maintained holding tanks are often underestimated source of contamination of soil, groundwater and surface water. As a rule, wastewater stored in holding tanks, should be transported and treated in municipal wastewater treatment plants (WWTPs). There are 2,257,000 holding tanks in Poland, located mainly in rural areas. The article presents the results of analysis of wastewater management in 20 rural and urban-rural communes, which were chosen at random from the total number of 2,174 communes in Poland. The only criterion of commune selection was total or partial lack of sewerage system. Analysis of the collected data showed that on average only 27% of liquid waste from holding tanks ended at the WWTPs. The median is even lower and amounts to 17.5%. More than 4,000 Mg of P and 26,000 Mg of N is dispersed in the environment in uncontrolled manner. Those diffuse point sources of pollution may be one of the reasons in the difficulty of achieving of good ecological status of rivers and affect the quality of the Baltic Sea.
