EVALUATION OF SURFACE WATER QUALITY IN PORSUK STREAM

Yıl 2016, Cilt: 4 Sayı: 2, 81 - 93, 25.03.2016

Öz

Porsuk Stream passing from the borders of  Eskişehir and Kütahya has a significant water supply, feeds Sakarya River, which has an important water potential in Turkey. In particular, Porsuk Stream is used as drinking water in the Eskişehir Provinces. Therefore, determination of water quality of Porsuk Stream has a great importance for the health of ecosystems for the region. Water samples were collected seasonally (2010-2011) from 13 stations selected on the Porsuk Stream and temperature, pH, dissolved oxygen, salinity, conductivity, ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, sulphate, phosphate, chemical oxygen demand, biochemical oxygen demand, total phosphorus, total chlorine, calcium, magnesium, sodium, potassium parameters were investigated. The detected physicochemical parameters were statistically compared among the stations and the effective factors were classified by using the Factor Analysis (FA). Also, Cluster Analysis (CA) was applied to the results to classify the stations according to physicochemical characteristics by using the Past package program. The data observed were evaluated with national and international water quality criteria. This study presents the necessity and usefulness of statistical techniques such as CA, FA and One-Way ANOVA in order to get better information about the surface water quality monitoring studies.

PORSUK ÇAYI YÜZEY SUYU KALİTESİNİN DEĞERLENDİRİLMESİ

Yıl 2016, Cilt: 4 Sayı: 2, 81 - 93, 25.03.2016

Öz

Porsuk Çayı, Kütahya ve Eskişehir il sınırlarından geçerek Türkiye’nin önemli su potansiyellerinden biri olan Sakarya Nehri’ni besleyen önemli bir akarsudur. Özellikle, Eskişehir iline kadar olan kısmının kullanma suyu olarak değerlendirilmesi nedeni ile Porsuk Çayı’nın su kalitesinin belirlenmesi bölgede bulunan ekosistemlerin sağlığı açısından büyük önem arz etmektedir. Su örnekleri Porsuk Çayı üzerinde seçilen 13 istasyondan (Mayıs 2010- Şubat 2011) mevsimsel olarak toplanmış ve sıcaklık, pH, çözünmüş oksijen, tuzluluk, iletkenlik, amonyum nitrojen, nitrit nitrojen, nitrat nitrojen, sülfat, fosfat, kimyasal oksijen ihtiyacı, biyokimyasal oksijen ihtiyacı, toplam fosfor, toplam klor, kalsiyum, magnezyum, sodyum, potasyum parametreleri belirlenmiştir. Tespit edilen fizikokimyasal parametreler istasyonlar arasında istatistiksel olarak karşılaştırılmış ve Faktör Analizi kullanılarak etkili faktörler sınıflandırılmıştır. Aynı zamanda, Past istatistik programı kullanılarak suda ölçülen parametrelere göre istasyonların benzerliğini belirlemek amacı ile kümeleme analizi uygulanmıştır. Elde edilen veriler uluslar arası ve ulusal su kalite kriterleri ile karşılaştırılmıştır. Bu çalışma, yüzey suyu izleme çalışmaları hakkında daha iyi bilgi edinebilmek için Kümeleme Analizi (CA), Faktör Analizi (FA) ve tek yönlü varyans analizi (One-Way ANOVA) gibi istatistiksel tekniklerin kullanımı ve gerekliliğini göstermiştir.
