Avaliação de impactos ambientais em área de disposição final de resíduos sólidos no semiárido

Abstract

Solid waste production is increasing and the correct final disposal is important to avoid environmental degradation. Unfortunately, only a few years ago in Brazil, the final solid waste disposal by the National Solid Waste Policy (PNRS) should be properly done in landfills. Due to the placement of waste in an inappropriate place, such as dumps, which after PNRS should be deactivated, as well as the environmentally recovered area and landfill. In this context the present research was carried out aiming to evaluate the environmental impacts in solid waste final disposal area in the city of Campina Grande. Visits were made on site, with photographic record, through the Ad Hoc method and checklist in the area. It was contacted that there was no removal of solid waste from the site, despite the area has been disabled for years, with microbiological activity and gas production. Several sites with leachate accumulation were observed. 4 ppm of the hydrogen sulfide gas was detected at two points. The soil and nearby water bodies are polluted and the use of the area by the nearby population is of concern. The current situation of the dump of Campina Grande-PB is worrying, and an area recovery plan is important.
