Abstracts

This study evaluated the influence of anthropogenic activities in water quality from rural and urban areas in Southern Brazil, above the Guarani aquifer. Water samples were submitted to microbial and physical-chemical analyses and Trophic State Index calculation. Results showed high levels of total phosphorus, nitrite, and E. coli in the urban area, and consequently a high Trophic State Index, indicating severe stress. In rural areas, elevated nitrate concentrations were found to be related to soil fertilization practices. This study reinforces the alert on the impact of riparian forest recuperation and wastewater treatment on water quality, especially in areas above important aquifer systems such as the Guarani.
