ASSESMENT OF THE WATER QUALITY OF SOME WELLS IN TODIREȘTI AND PĂRHĂUȚI SETTLEMENTS

Abstract

We analyze the pollution of the waters from wells in the built areas of Todirești and Părhăuți for the following parameters: ammonium, nitrite, nitrate, orthophosphate and sulfide (water samples collected on August 29th, 2015). The groundwater is more polluted in Părhăuți than in Todirești. The highest water pollution is caused by nitrates and orthophosphates. There is a relevant positive correlation between the depth to groundwater table and the orthophosphate concentration in Părhăuți. The water pollution with orthophosphates is caused by domestic waters rich in detergents. At least the orthophosphate concentration will increase in the near future due to the increasing standard of living.
