Use of Water Quality Index to evaluate the groundwater characteristics of villages located in Edirne Province
Abstract
In this research, water quality of groundwater of some villages located in Edirne Province of Turkey were evaluated by using Weighted Arithmetic Water Quality Index (WAWQI). Groundwater samples were collected from ten villages in winter season of 2019. Thirteen parameters including total dissolved solids – TDS, oxygen saturation – OS, salinity, pH, dissolved oxygen – DO, turbidity, nitrate – NO3, electrical conductivity – EC, nitrite – NO2, sulphate – SO4, oxidation – reduction potential – ORP, phosphate – PO4 and chemical oxygen demand – COD were measured in groundwater samples. According to detected data, groundwater of the region has 1. Class quality for dissolved oxygen, pH, nitrite, sulphate and COD parameters in general and has 2. Class quality for oxygen saturation, EC, nitrate and phosphate parameters in general. It was also determined that any investigated water quality parameter has not exceeded the drinking water standards. As a result of WAWQI, the values of overall WAWQI were recorded within the permissible limits (<100) and the groundwater quality of the region was found as "A grade" water quality characteristic.
