During the communist government the agricultural lands of Dolj County (South-West Romania) were intensively fertilized. The environmental risks and the harmful impact on human health were ignored. Thus Dolj became one of the most nitrogenous polluted regions in the country according to the infant methaemoglobinemia average incidence, the annual frequency of the disease and the percentage of nitrates polluted wells. Purpose. To evaluate the dynamics of well water nitrates pollution around the 94 rural communities of the county after the communism breakdown (December 1989). Methods. We collected data concerning the fertilization level of agricultural lands from the local institutions and measured the nitrates and nitrites concentrations in 5076 well water samples. Results. The amount of nitrogenous fertilizers progressively decreased from 94.1 kg active substance/ha in 1990 (figures similar to the 1980s - 104.3 kg active substance /ha) to 65.6 kg active substance/ha in 2004. The calculation of the well water nitrates average concentration in the county underlines the decreasing evolution of these pollutants - from an average of 130.29 mg/L (95% CI=116.22-144.35) in 1990 to 56.25 mg/L (95% CI=50.1-62.41) in 2004 following a linear decreasing pattern (y = - 5.3589x +136.02). In comparison with the well water nitrates concentration in 33 villages of the county in 1979, our results emphasizes a significant decrease of these pollutants (p < 0.001). Conclusion. The decrease of the agricultural lands fertilization and thus the decreasing evolution of the nitrates concentration in wells have to be noted in Romania after 1989.
