Abstract: | This study aims to investigate the degree of the influence of contaminant sources on both the surface (Porsuk River) and groundwater
in the Eskisehir plain, (Turkey) and to determine the changes in groundwater quality after the sewage system was started in
1998. For this purpose surface and groundwater samples were collected from various locations in the Eskisehir plain between
May and October, 2001. The Porsuk River is already polluted in the upstream wastewater and by industries such as Nitrogen
Fertilizer Factory, Sugar-beet Factory, and Magnesite Factory located around the city of Kutahya. This high-contaminated water
forms an eutrophic environment which generates high phosphorus and nitrogen in downstream flow. Agricultural and industrial
activities in the Eskisehir plain are an additional source of the pollution of the Porsuk River. The study revealed that some
trace elements, Pb, Cr, Mn, Fe, and Cd, are present in high concentrations both in the surface and groundwater besides extremely
high quantities of phosphorus, nitrogen and sulfide compounds. In addition, analyses of samples also indicated that there
are no considerable contaminations in terms of local pesticides. High concentration of Cd, N and S are found in the groundwater.
On the basis of a detailed analysis of the groundwater in the Eskisehir plain, it is concluded that groundwater is not suitable
for drinking according to Turkish standards, European Union Standards (EU) and World Health Organization (WHO).
