Investigation of Water Quality and Pollution Level of Lower Melet River, Ordu, Turkey

33674

Some water quality parameters of the Lower Melet River were determined by taking monthly samples, starting in October 2013 and end up in September 2014. The means obtained data were given as (min–max) mean as follow; pH;(6.93 – 8.8) 7.96, dissolved oxygen (DO);(5.4-15.4) 11.4 mgL^-1, saturation (%);(59-201) 117, temperature;(4.6-27.2) 14°C, total dissolved solid (TDS);(106-320) 161 mgL^-1, conductivity (EC);(124-520) 216 μScm-1, salinity;(0-0.4) 0.11 ppt, biochemical oxygen demand (BOD5);(0.6-4.8) 2.3 mgL^-1, total alkalinity (TA);(55-100) 79 mgL^-1 CaCO3, total hardness (TH); (70-125) 97 mgL^-1 CaCO3, chlorophyll-a;(1.6-10.4) 3.78 μgL^-1, total ammonia nitrogen (TAN); (0.33-1.27) 0.53 mgL^-1, total phosphate (TP);(0.08-0.85) 0.40 mgL^-1 soluble reactive phosphorus (SRP); (0.01-0.12) 0.04 mgL^-1, chlorine;(0.04-0.75) 0.19 mgL^-1, silica;(2.37-6.08) 4.51 mgL^-1, phenol; (0.04-1.77) 0.43 mgL^-1, nitrite; (0.01-0.12) 0.04 mgL^-1, nitrate;(0.29-3.39) 1.22 mgL^-1, sulphite;(1.93-3.65) 2.34 mgL^-1, sulphate;(1.62-13.29) 10.42 mgL^-1, surfactant (anionic);(0.33-1.62) 0.97 mgL^-1, potassium;(2.75-15.4) 7.2 mgL^-1, total suspended solids (TSS);(8.45-147.7) 49.75 mgL^-1 , and redox potential ;(-156 / -28) -86.78 mV. Sediment organic matter % and pH were averaged as (2.9-9.1) 5.77 and (6.71-8.3) 7.53, respectively. Obtained data showed that the water quality of Melet River may suitable for irrigation but may not be a suitable living habitat for the living beings. According to the class of surface water quality regulation getting into the category of mild contaminated according it’s average total phosphate rate of 0.40 mgL^-1, TAN level of 0.53 mgL^-1, nitrite rate of 0.04 mgL-1 and severely contaminated according it’s average surfactant (anionic) level of 0.97 mgL^-1 and phenol level of 0.43 mgL^-1.
