The effects of sand pits and sand extractions region on Karasu Stream (van) to water quality criteria

Abstract

In this study, physical, chemical and microbiological parameters were analyzed in water samples in order to determine the effects of sand pits and sand extraction in Karasu Stream. The water quality data were collected monthly between June 2014 and May 20'6 from five sampling stations distributed along the stream and 39 parameters were examined such as dissolved oxygen, dissolved oxygen saturation, temperature, pH, electrical conductivity, flow, total suspended solids, turbidity, chlorine, calcium, magnesium, total hardness, carbonate, bicarbonate, total alkalinity, nitrate, nitrite, ammonium, ammonia, orthophosphate, total phosphor, sulfate, cyanide, silicon, silicon dioxide, biological oxygen demand, chemical oxygen demand, fluoride, fecal coliform, copper, aluminum, zinc, chromium, manganese, iron, molybdenum, cobalt, nickeland sediment accumulation. Turkish, EU and WHO water quality standarts were used in the evaluation of the results. Sand pits, sand extractions and the pollution caused by the settlement around the stream ruined the water quality of the stream and threatened the lives of the fish living in Karasu.
