Abstract:
In this study, analyzes were carried out monthly between May 2015 and May 2016 from the Aygır Lake and the irrigation pool for examining its water quality change and management. On-site measurements were found as average water temperature 9.9±0.5 C, pH 8.14±0.00, dissolved oxygen 8.1±0.4 mg/L, oxygen saturation % 76.6±2.4, EC 353.1±4.1, SPC 435.0±4.5 μS/cm, salinity ‰ 0.21±0.003, TDS 0.2881±0.0026 g/L, turbidity 0.6±0.1 NTU and transparency 5.8±0.7 m. Laboratory analyzes were found as average Cl 17.3±0.4 mg/L, Ca 54.3±1.7 mg/L, Mg 40.6±1.0 mg/L, CO3 9.8±0.9 mg/L, HCO3 256.9±5.0 mg/L, total hardness 302.7±4.8 mg/L, total alkalinity 235.1±2.9 mg/L, NO2 17.8±2.0 µg/L, NO2-N 5.9±0.6 µg/L, NO3 1.2±0.1 mg/L, NO3–N 0.03±0.00, NH4 0.06±0.00 mg/L, NH3 0.05±0.01 mg/L, NH3-N 0.04±0.00 mg/L, SO4 11.7±0.5 mg/L, o-PO4 21.7±4.8 µg/L, K 1.72±0.07 mg/L, Al 1.13±0.31 µg/L, Fe 0.0±0.0 mg/L, Cr 0.0±0.0 mg/L, Zn 0.22±0.02 µg/L, Cu 3.7±0.2 µg/L, F 0.56±0.06 mg/L, Mn 3.2±0.2 µg/L, Ag 0.15±0.17 µg/L, As 1.6±0.4 µg/L, Cd 1.1±0.2 µg/L, Pb 0.21±0.03 mg/L, B 0.01±0.00 mg/L, Br 0.12±0.01 mg/L, I 0.16±0.01 mg/L, Na 27.0 ±2.8 mg/L, Mo 1.69±0.04 mg/L, CN 1.19±0.10 µg/L, Co 0.0±0.0 µg/L, Ni 0.0±0.0 µg/L, Si 5.74±0.05 mg/L, SiO2 24.27±0.30 mg/L, BOD5 0.0±0.0 mg/L, COD 0.0±0.0 mg/L, SS 3.8±0.5 mg/L, MEI 10.3±0.2 mg/L/m, SAR 0.5736 and fecal coliform 0.5±0.5. Aygır Lake water quality index was calculated 149.41 as AG-WQIdrink, and 76.11 as AG-WQIfishery. Aygır Lake was found to be not-polluted, proper for drink, usage, fishery and irrigation; Aygır lake was adversely affected from near settlements and agricultural activities.
