Water Quality Characteristics of Some Ponds in Van (Türkiye) Province
Abstract
This study was conducted to investigate the physical and chemical properties of the waters of Lower Tulgalı, Oymaklı, Sırımlı, Morçiçek and Sağmalı ponds in Van province during the Autumn (November 2022), Spring (May 2023) and Summer (July 2023) seasons. On site measurements were as follows: Dissolved oxygen 8.70±0.77 mgL-1, water temperature 13.56±0.62°C, turbidity 18.09±12.57 NTU, electrical conductivity 423.67±156.37 μScm-1, salinity 0.21±0.08 mgL-1, pH 8.77±0.18, TDS 215.26±80.04. The mean levels of chemical parameters were determined as Cl2 27.36±3.81 mgL-1, Ca+2 52.50±14.43 mgL-1, Mg+2 22.95±10.49 mgL-1, Ca+Mg 151.97±48.96 mgL-1, CO32- 6.21±0.92 mgL-1, HCO3- 130.61±61.39 mgL-1, NO2- 0.07±0.02 mgL-1, NO2--N 0.02±0.01 mgL-1, NO3- 3.93±2.38 mgL-1, NO3--N 0.94 ±0.56 mgL-1, NH3 0.36±0.45 mgL-1, NH3-N 0.31±0.39 mgL-1, NH4 0.38±0.47 mgL-1, PO4-3 0.10±0.10 mgL-1, P 0.03±0.04 mgL-1, SO4 102.95±32.12 mgL-1, K 2.16±1.01 mgL-1, Na 9.76±3.12 mgL-1, B 0.56±0.38 mgL-1, total hardness 20.33±10.82 mgL-1, organic matter 1.35±0.39 mgL-1, SAR 0.29±0.07 mgL-1, Cr+6 0.001±0.001 mgL-1, Fe+2 0.032±0.023 mgL-1, Mn+2 0.075±0.129 mgL-1, Cu 0.005±0.003 mgL-1, nickel and cobalt values were below measurable levels and Zn was determined as 0.010±0.003 mgL-1. The results obtained were evaluated according to the relevant water quality regulations. According to YSKYY and SKKY, all the measured parameters excluding pH indicated that pond waters were suitable for agricultural irrigation. According to ASSKY, all parameters excluding ammonia (except Sırımlı and Morçiçek) and nitrite were suitable for carp and trout production.
