Description
Summary:The aim of this study is to understand the effects of pollution of anthropogenic origin on water quality in Yalvac Basin, part of the Egirdir Lake catchment. Surface discharge from the basin to the lake is 63 m³/year and underground discharge is 114 m³/year. Possible water pollution is categorized into domestic, industrial and agricultural origin. Domestic and industrial wastewaters, including effluents from leather tanneries are discharged, without being purified, into Yalvac Stream, which flows into Egirdir Lake directly or via the drainage canal. Surface waters flowing into the lake are used in winter for irrigation of agricultural areas. In agricultural areas natural and synthetic fertilizers and pesticides are used extensively. Lake Egirdir is used as a source of drinking water. Sampling sites were established for surface and underground waters, taking into account the known point sources of pollution. These sites were sampled in May and October of 2002, and analysed chemically. Cr³⁺ and Pb²⁺ concentrations exceed standard limits, meaning that pollution caused by effluent from the tanneries is adversely affecting the water quality in the lake.
