Abstract:
Potable water sources worldwide have started to decline in volume and deteriorate in quality. This situation is present in Romania, in the plain and plateau area of Moldova. This area has a small number of viable drinking water sources from groundwater, rivers and lakes. Rural settlements in this area are the most affected by the lack of unpolluted water sources. The natural pollution occurs due to the nature of the rocks from the water sources’ site, where the presence of sulphates and chlorides is predominant. The researches show exceedings to almost the entire nutrient group. The highest concentrations of nitrates are recorded in the Jijia and Bahlui hydrographic basin. The analyses carried out in Iaşi area regarding the groundwater quality parameters have highlighted high concentration of sulphates. This exceeds the standardised value so that the groundwater source is improper for catchment and usage as drinking water for the population.
