Chloride-discharge relationships at several stations on Turkish streams are investigated, both qualitatively and quantitatively, to identify natural and anthropogenic sources of chloride. Simple expressions are used to distinguish among sources. Linear regression analysis is conducted to estimate parameters of the models. Five groups of stations are distinguished respective to different sources of chloride and change of chloride concentration with stream discharge. Emphasis is placed on the identification of anthropogenic sources of chloride to aid in water pollution control strategies. The polluted Sakarya River and its primary tributary, the Porsuk Stream, are studied in detail to trace chloride behavior along the waterway and to assess the level of pollution from cities discharging to the streams. Among natural sources of chloride, evaporite sediment sources are examined in detail.
