ASSESSMENT OF THE STREAM NETWORK POLLUTION IN THE EĞIRDIR LAKE BASIN (TURKEY) USING WATER QUALITY INDEX AND MULTIVARIATE ANALYSIS

Öz

Eğirdir Lake which is one of the sources of the drinking water of Isparta (Turkey) is the second largest fresh water lake of Turkey. The most important surface waters in the study area are Pupa, Hoyran, Yalvaç and Çay Streams. Pollutants from point and nonpoint sources are transported into the lake via these four main streams. In this study, stream water quality, seasonal variations and its suitability for drinking usage were evaluated. Parameters which are controlled to chemical variations of stream water, were analyzed with R-mode factor and correlation analysis. According to R-mode factor analysis, EC, NO₃, NO₂, NH₃, BOD, COD in dry season and K, HCO₃, Cl, NH₃, NH₄, orthophosphate, total phosphorus, BOD, COD in wet season are the most important parameters. In addition, Water Quality Index (WQI) was applied to suitability for drinking purpose and evaluation of stream water quality. According to the WQI in dry season, 46.66% of stream water samples exhibited ‘‘good water’’, 20% exhibited ‘‘poor water’’, and 33.33% exhibited “very poor water”. In wet season 46.66% of stream water samples exhibited ‘‘excellent water’’, 13.33% exhibited ‘‘good water’’, 26.66% indicated ‘‘poor water’’ and 13.33% showed “very poor water”.

EĞİRDİR GÖLÜ HAVZASI AKARSU AĞINDAKİ KİRLİLİĞİN SU KALİTE İNDEKSİ VE ÇOK DEĞİŞKENLİ ANALİZ YÖNTEMİ İLE DEĞERLENDİRİLMESİ

Öz

Eğirdir Gölü Türkiye'nin ikinci büyük tatlı su gölüdür ve Isparta'nın içme suyu ihtiyacının bir kısmı bu gölden sağlanmaktadır. Havza içerisinde akan en önemli yüzey suları Pupa, Hoyran, Yalvaç ve Çay dereleridir. Noktasal ve noktasal olmayan kaynaklardan gelen kirleticiler bu dört ana akış yoluyla göle taşınır. Bu çalışmada, dere sularının kalitesi, mevsimsel değişimleri ve içme kullanımına uygunluğu değerlendirilmiştir. Dere sularının kimyasal varyasyonlarına göre kontrol edilen parametreler R-mod faktörü ve korelasyon analizi ile analiz edilmiştir. R-mod faktörü analizine göre, kurak dönemde EC, NO₃, NO₂, NH₃, BOİ ve KOİ kurak dönemde; K, HCO₃, Cl, NH₃, NH₄, ortofosfat, toplam fosfor, BOİ ve KOİ ise yağışlı dönemde en önemli parametrelerdir. Ayrıca, akarsu su kalitesinin araştırılması ve içme amaçlı kullanıma uygunluğa için Su Kalitesi İndeksi (WQI) uygulanmıştır. Kurak dönem WQI indeksine göre, dere suyu örneklerinin 46.66%'sı "iyi su", 20%'si "zayıf su", 33.33%'ü "çok zayıf su" özelliği göstermektedir. Yağışlı dönemde örneklerin 46.66%'sı "mükemmel su", 13.33%'ü "iyi su", 26.66%'sı "zayıf su" ve 13.33%'ü "çok zayıf su" özelliği göstermektedir.
