The correlation and regression study deals with the drinking water quality of Susehri located at Central Anatolian region of Turkey. Over the period between May 2013 and June 2014, twelve field surveys were conducted and water samples were collected from four different stations in Susehri. In the collected water samples, totally fourteen physicochemical parameters were analyzed. Physicochemical parameters studied were in varying ranges such as water temperature 14.00-20.60 degrees C, dissolved oxygen 3.80-6.50 mg/l, BOD5 0.50-1.60 mg/l, pH 7.00-8.00, ammonium 0.00-0.16 mg/l, nitrite 0.00-0.25 mg/l, nitrate 0.00-2.30 mg/l, ortophosphate 0.00-0.25 mg/l, chloride 4.00-12.00 mg/l, carbonate hardness 2.20-8.20 degrees dH, acid binding capability 0.80-3.00 mmol/l, total hardness 2.60-9.20 degrees dH, calcium 18.56-65.69 mg/l and magnesium 11.13-39.38 mg/l in Susehri. Highly positive correlation coefficient is observed between carbonate hardness and acid binding capability (R=0.975**), carbonate hardness and total hardness (R=0.891**), carbonate hardness and calcium (R=0.899**), carbonate hardness and magnesium (R=0.892**), acid binding capability and total hardness (R=0.892**), acid binding capability and calcium (R=0.899**), acid binding capability and magnesium (R=0.893**), total hardness and calcium (R=0.996**), total hardness and magnesium (R=1.000**), calcium and magnesium (R=0.996**). The correlation and regression study showed significant linear relationship among different pairs of water quality parameters in Susehri. Based on the data recorded, all of the physicochemical parameters are well within the permissible limits as per standards. The quality of water is safe for drinking purposes in Susehri.
