Determination of Snowmelt Water Quality in Outdoor Green Areas: a Case Study at Van Province (Turkey)
(Istanbul Univ Press, Fac Aquatic Sciences, 2021) Yeler, Okan; Divrik, Menekse Tas; Elipek, Belgin Camur
Freshwater resources are used for many purposes such as drinking, tap water, industrial usage and agricultural irrigation. Although unpolluted surface waters and groundwater are preferred for the irrigation of landscape plants in parks and gardens, snowmelt water is generally ignored. Like other precipitation types, snow can absorb solid and liquid substances in the atmosphere and it can rain on the earth with its natural chemical structure changed. Also, this water from snowmelt which includes different chemicals can enter surface waters and groundwater resources. In this study, the snowmelt water quality in outdoor green areas of the Van Province was examined. Some physico-chemical features (pH, conductivity, salinity, Ca, Mg, total hardness, Cl, NO3-N, NO2-N, SO4, and PO4) of the snow samples were taken at monthly intervals from six sampling stations between the dates of December 2019 - February 2020. Also, metal ion concentrations (Cd, Pb, As, Cu, Cr, Co, Ni, Zn, Fe, Mn, B, Se, Ba, Al, Na, Be, V, Mo, Si, K, Sr, Ag, Sb, Tl) and the values of SAR (Sodium Adsorption Ratio) and Na% in some sampling stations, which have intense industrial and settlements located in the area, were determined to evaluate the water quality level of the snowmelt water. While, it was observed that some parameters values exceeded the first quality level when compared with the quality levels of the surface water resources control regulation of Turkey and the rates in irrigation water quality values, a general evaluation of the results showed that snowmelt can be alternative irrigation water for plants. Also, the species of the landscape plants in the studied area were identified and the possible effects of the parameters on the development of the plants were discussed.
Spatial and Temporal Evaluation of the Physicochemical Quality of Domestic/Industrial Water in the Kirklareli Reservoir (Turkish Thrace)
(Serbian Chemical Soc, 2022) Guher, Huseyin; Oterler, Burak; Elipek, Belgin Camur; Yeler, Okan; Aydin, Gazel Burcu
The Kirklareli Reservoir, located in the Meric-Ergene River Basin, is an important drinking/industrial freshwater resource of the Kirklareli Province. In order to ensure the sustainable use of this important reservoir, its current situation should be examined periodically and evaluated by multivariate analyses. For this reason, water samples were taken between the dates April 2018 and February 2019 at monthly intervals from 3 different stations. The data on the environmental and physicochemical variables (water temperature, dissolved oxygen, pH, salinity, conductivity, total dissolved solids, chlorophyll-alpha, light permeability, fluoride, chloride, NO2-N, NO3-N, PO4, SO4 and essential/potentially toxic elements) were measured and evaluated according to the classes of surface water quality control regulation of Turkey. The parameters exceeding first-class water quality values (chlorophyll-alpha, pH, NO2-N, chloride, selenium) were mapped in GIS using the spline integration approach. In addition, the sodium absorbtion ratio, Kelly index values and magnesium ratio, were calculated to evaluate the water quality for agricultural irrigation water standards. The water quality of the reservoir was evaluated using multivariance analyses (Bray-Curtis similarity index, correspondence analyses, Pearson correlation index). As a result, it was emphasized that the use of the GIS approach is a potential useful method for monitoring the sustainable water quality of the Kirklareli Reservoir, which was determined to have an oligomesotrophic character.
