Avalia??o da contamina??o de efluentes domésticos em po?os sobre área de restinga

摘要

The purpose of this study was to investigate the contamination of septic tanks in?the supply wells of a population settled over a sandbank area, the Lagomar neighborhood,?in the city of Macaé (RJ). The neighborhood is located in the macro areas of the northern?border, adjacent and buffer zone of Restinga de Jurubatiba National Park, with great?ecological relevance and scenic beauty, and shelter for numerous coastal lagoons and?endemic species. The studied area has low-income population, and no systems of?wastewater treatment and public water supply, thus increasing the risk of diseases?related to poor environmental sanitation. The presence of fecal coliforms in all samples,?including a sample of treated water, indicates health risks to the local population, as?well as risks of ecosystem change in the National Park and its surroundings.
