Liquid manure from pig breeding facilities as a potential water contaminant

Intensive pig breeding used for the last fifty years has resulted in several-fold increase in the productivity of this livestock production system. However, modern technology achievements in pig breeding take their toll in the form of both immediate and general environmental hazards. The potential adverse environmental effects, mostly due to liquid waste abundance, generally manifest on water flows and drinking water resources. Based on these considerations, samples of water used for drinking and watering taken from a spring, artesian wells and sweep wells in the Sava River basin in west Slavonia, Croatia, were analyzed. A swine farm with about 25, 000 fattening pigs per year has been operating in the area for some thirty years. The liquid manure produced on the farm is being processed and discharged through the lagoon system onto 800 ha of arable land as replenishment for crops, mostly cereals. The aim of the study was determine the quality of water in the area with respect to the animal waste from the swine farm and surrounding fields.
