Abstract
Pig farms in Leningradskij Oblast, Russia are usually large -20,000 to 60,000 pigs per farm. As these farms discharge pig slurry into the adjacent rivers flowing into the Baltic Sea, there is a potential risk for pollution of both the rivers and the sea. This risk was assessed at the Vostochnii pig complex, which holds 60,000 pigs. The impact of slurry treatment on water quality in the groundwater (GW) and the river Igolinka, the recipient of the treated slurry, was investigated. The results indicated that untreated and treated slurry from pig farm wastewater treatment systems are potential point sources of environmental pollution. Generally, the GW was characterized by rather high contents of ammonium and chemical and biological demand for oxygen (COD, BOD). Similarly, the river exhibited high COD and BOD, contained considerable amounts of suspended substances and total P, and small quantities of NO3-N and NH4-N. Of the biological parameters investigated, the elevated population of fungi and pathogenic faecal bacteria Escherichia coli (100-10,000 CFU E. coli cells ml(-1)) determined in the river posed a potential health risk. Equally important was the marked total P load in the river, part of which could be transported to the Baltic Sea, where it could trigger eutrophication
