Types and Sources of Underground Water Table Pollution in Sânmihaiu German Settlement (Timiş County) – Preliminary Analysis

Abstract: The drinking water of German Sânmihaiu, located at about 15 km South-Western from Timişoara city, is polluted. There are some small farms in the settlement, which pollute the underground water with sulphates, nitrites and ammonia. Waste thermal waters resulted as open discharges from the local swimming pool are added. 22 water samples constituted the basis of this study, accompanied by questionnaires. The chemical analysis of the test was performed in the laboratory. The study also uses digital cartography methods, which outlined the spatial disparities regarding the pollution of each underground water table. The concentration of ammonia and nitrites has considerably decreased as compared to the last two decades, when intensive agriculture at CAP level was based on chemical fertilizers. Yet, the pollution from unmonitored sources continues to represent a problem.
