Microbiological and chemical investigation of drinkable water of Karacomak lake in Kastamonu

This study deals with the chemical and microbiological analysis of some samples which have been taken from Karaçomak Lake in Kastamonu. This lake is a staple source of potablo water in the city of Kastamonu. In this study drinking water samples, from the four stations sources of Karaçomak Dam Lake in Kastamonu, were analyzed physicochemical and microbiological, to find out their suitability for drinking purposes. All the result of chemical, physical, and bacteriological analysis of water had been compared with Turkish Republic Water Regulations Intended for Human Consumption and World Health Organisation Guidelines of the quality of drinking water. Temperature, pH, dissolved oxygen, total alkalinity, total hardness, turbidity, total nitrate, nitrite, phosphate and ammonium were measured, average 4.45±0.75 ºC, 8.84±0.12, 9.90±1.30 mg L-1, 37.50±11.09 mg L-1, 25.63±6.04 mg L-1, 4.69±5.96 FTU, 0.50±0.28 mg L-1, 0.03±0.04 mg L-1, 0.18±0.095 mg L-1 and 0.08±0.06 mg L-1, respectively. Total germ count was found to average 115±124 cfu mL-1. Also Pseudomonas aeruginosa was isolated from water samples of Karaçomak Dam Lake
