WATER CHEMICAL ANALYSIS OF WELLS IN THREE SETTLEMENTS OF SUCEAVA PLATEAU, ROMANIA

Abstract

Water from wells in Humoreni, Comănești and Soloneț (Suceava County, Romania) was sampled in order to measure the concentration of ammonium, nitrite, nitrate, orthophosphate and sulfide. The measured values were used to map the spatial variation of each parameter. Relevant spatial resolution was obtained due to the 15 sampling points in each settlement. The water quality was assessed according to the national standards. The worst water quality (deteriorated class) was recorded in Humoreni and Soloneț (for the orthophosphate parameter), while in Comănești the same water quality was recorded for nitrate. Mediocre water quality was recorded for ammonium in Humoreni; the same settlement also had the highest nitrite concentration (as compared to the other settlements in this study), included in the average water quality class. Sulfide was barely present in the analyzed samples and did not exceed the maximum admissible concentration; however, there are higher concentrations in Soloneț village. The main cause of the observed ground water pollution is the lack of sewerage systems in the studied settlements.
