Bu çalışma, Türkiye’nin Doğu Akdeniz Bölgesi’nde yer alan Göksu Irmağı’nın hidrojeokimyasal özelliklerini ve su kalitesini mevsimsel olarak değerlendirmeyi amaçlamaktadır. Araştırma kapsamında, kış ve yaz dönemlerinde 17 farklı istasyondan alınan su örnekleri analiz edilmiştir. Çalışmada, suyun fiziksel ve kimyasal özellikleri (sıcaklık, pH, çözünmüş oksijen, iletkenlik, iyon konsantrasyonları vb.) incelenmiş ve elde edilen veriler ulusal (TSE 266) ve uluslararası (WHO) standartlarla karşılaştırılmıştır. Sonuçlar, Göksu Irmağı’nın su kalitesinin mevsimsel olarak önemli değişiklikler gösterdiğini ortaya koymuştur. Yaz aylarında sıcaklık, iletkenlik ve çözünmüş madde miktarlarında artış gözlenirken, kış aylarında fosfor ve amonyum gibi besin elementlerinin yüksek değerlere ulaştığı tespit edilmiştir. Piper ve Gibbs diyagramları, suyun kimyasal bileşiminin büyük ölçüde kayaç çözünmesi ve buharlaşma süreçlerinden etkilendiğini göstermiştir. Tarımsal faaliyetlerden kaynaklanan gübre ve pestisit kullanımı ile yerleşimlerden kaynaklanan evsel atıklar, su kalitesini olumsuz etkileyen başlıca faktörler olarak belirlenmiştir. Çalışma, Göksu Irmağı’nın su kalitesinin korunması ve sürdürülebilir yönetimi için tarımsal faaliyetlerin kontrol altına alınması, gübre ve pestisit kullanımının azaltılması, yerel halkın bilinçlendirilmesi ve su yönetimi politikalarının geliştirilmesi gerektiğini vurgulamaktadır. Elde edilen bulgular, Akdeniz havzalarında su kaynaklarının korunması ve sürdürülebilir kullanımı için önemli bir referans niteliğindedir.

HYDROGEOCHEMICAL PROPERTIES AND QUALITY ASSESSMENT OF THE GÖKSU RIVER (TURKEY)

Öz

This study aims to evaluate the hydrogeochemical properties and water quality of the Göksu River, located in the Eastern Mediterranean Region of Turkey, on a seasonal basis. Within the scope of the research, water samples were collected from 17 different stations during the winter and summer seasons and analyzed. The study examined the physical and chemical properties of the water (temperature, pH, dissolved oxygen, conductivity, ion concentrations, etc.) and compared the obtained data with national (TSE 266) and international (WHO) standards. The results revealed that the water quality of the Göksu River shows significant seasonal changes. While increases in temperature, conductivity, and dissolved solids were observed in the summer months, high levels of nutrients such as phosphorus and ammonium were detected in the winter months. Piper and Gibbs diagrams showed that the chemical composition of the water was influenced mainly by rock dissolution and evaporation processes. Fertilizer and pesticide use from agricultural activities and domestic waste from settlements were identified as the main factors negatively affecting water quality. The study emphasizes the need to control agricultural activities, reduce fertilizer and pesticide use, raise awareness among the local population, and develop water management policies to protect the water quality of the Göksu River and ensure its sustainable management. The findings obtained are an important reference for the protection and sustainable use of water resources in the Mediterranean basin.
