Investigation of Nitrate, Nitrite Pollution Levels and Organic Matter Amounts of Artesian Waters of Aydın Region

Among the pollutants that can spread over large areas, nitrate, nitrite and organic matter are considered as an important indicator of pollution of the environment. It is known that there is a high connection and relationship between agricultural activities and nitrate contaminations. This study was carried out to determine the amount of nitrate, nitrite and organic matter, which are important indicators of water pollution, in artesian waters taken from various districts of Aydın. The artesian waters used in the study were obtained from randomly selected artesian wells close to the settlements of 9 districts of Aydın province (Germencik, Çine, Kuşadası, Bozdoğan, Efeler, Köşk, Söke, Yenipazar, Koçarlı) in September 2019. Nitrate and nitrite analysis in waters by colorimetric method; organic matter analysis was performed by titrimetric method. Underground water resources in Aydın are generally used for agricultural irrigation and to meet the water needs of farm animals. In the water samples taken in the study, nitrate and nitrite amounts were determined below the upper limit determined by TSE. Despite this, the amounts of organic matter were found in all samples; It is above the limit values of 0.1-2 mg/l for groundwater. It is thought that this contamination due to organic matter may have been caused by domestic contamination.
