Avaliação de impactos ambientais do aterro sanitário em Sousa-PB.

Abstract

The uncontrolled generation of Urban Solid Waste (USW) constitutes a global environmental issue, given that, most of the time, the final disposal of these USW is inadequately carried out, resulting in numerous environmental impacts that adversely affect public health and the quality of the environment. In this context, the present study aimed to evaluate the environmental impacts generated during the operational phase of the Sanitary Landfill of SousaPB. The methodological steps included the survey of project activities, conducting a simplified diagnosis of the area, identifying and analyzing environmental aspects and impacts, calculating the Waste Landfill Quality Index (WLQI), and proposing measures, plans, and environmental control programs. These steps were developed based on research in scientific and technical literature, field visits, and photographic records. Based on the results, it was found that the most impacted aspects were the abiotic and anthropic factors, and the most affected environmental components were the soil, air, and health. 32 environmental impacts were identified, with 22 of them having a negative connotation for the area of influence. The WLQI for the studied area was 6,82, indicating inadequate operational conditions. Among the proposed measures, plans, and programs, the environmental education program targeting landfill workers and the general population stands out. In conclusion, it is expected that the results obtained in this study will contribute to the sustainable development of the activities of the Sanitary Landfill in SousaPB.
