Abstract

Su
kalitesi değerlendirmesi, çevresel yönetim planlarının daima önemli bir parçası olmuştur. Bu çalışmada, Doğu
Trakya Bölgesi’ndeki yeraltı sularının içme ve sulama amaçlı kalitesi
değerlendirilmiş ve sonuçların mekânsal dağılımı haritalanmıştır. Çalışma
alanındaki 18 adet derin su kuyusundan alınan örneklerin su kalitesinin
değerlendirilmesi amacıyla hidrokimyasal özellikleri saptanmıştır. İnsani
tüketim amaçlı su kalitesi değerlendirmesi için Su Kalite İndeksi (SKİ)
hesaplanmıştır. SKİ değerleri, yeraltısularının % 52’sinin tarımsal ilaçlamadan
dolayı “kötü” ve “çok kötü” sınıfında olduğunu göstermiştir. Bununla beraber,
sulama amaçlı olarak yeraltı sularının büyük kısmının, sodyum absorbsiyon oranı
(SAR), artık sodyum bicarbonat (RSC), sodyum yüzdesi (Na%) ve magnezyum
tehlikesi (MH) açısından uygun olduğu görülmüştür.

Application of Water Quality Index with the Aid of Geographic Information System in Eastern Thrace to Assess Groundwater Quality

Abstract

Water quality assessment has always been a major part
of environmental management plans. In this study, the groundwater quality and
spatial distribution in the eastern Thrace region was assessed and mapped for
agricultural and drinking purposes. Groundwater samples (n = 18) were collected
from deep wells in the study area and analyzed for hydrochemical properties for
the water quality assessment. The Water Quality Index (WQI) was calculated for the
quantification of water quality for human consumption. The WQI values showed
that 52 % of the groundwater samples fall in the “poor” and “very poor” category
due to agricultural impact. Nevertheless, the majority of the groundwater were
suitable for irrigation in terms of sodium absorption ratio (SAR), residual
sodium carbonate (RSC), sodium ratio (Na%) and magnesium hazard (MH).
