groundwater contamination - Opis:
- The study presents the behavior of nitrate in the recharge zone of Tursko B well-field (south Wielkopolska, Poland). The presence of a contaminant plume originated from drainage ditches was documented. The contamination is manifested mainly by high concentration of nitrate (>80 mg/dm3). It was recognized that the contaminant plume migrates in the aquifer along a flow path from the contamination source to the wells. The factor that retards nitrate migration is denitrification. As a result of the denitrification, the nitrate concentration decreases systematically along flow lines, but the concentration of other parameters - products of denitrification (sulfate and total hardness) increases. The occurrence of denitrification was confirmed by measuring the gaseous excess of N2 (the product of denitrification) and by using the isotopes of 15N and 18O dissolved in nitrate.
