Risks of environmental impacts arising from the irregular deposition of Civil Construction Waste in the Metropolitan Region of Recife watersheds

Abstract

The irregular disposal of Construction Waste (CW) causes a series of environmental impacts on water resources, such as damage to health, pollution of water, soil and aesthetics to cities. The objective of this research is to map the irregular deposition sites of CW in the Metropolitan Region of Recife (MRR) and to evaluate the environmental impacts they cause on the watersheds. In order to identify the areas, the incursions were made to 7 municipalities studied, where the disposal points were identified, and plotted on Google Earth software. After data collection, 1252 points were identified, and were divided in risks classes to analyze which areas have a greater risk of causing environmental impacts. It was verified that the Grupos Litorâneos 1 (GL1) watershed presents more areas of high environmental impact, and the Capibaribe watersehd has the highest amount of irregular disposal points. Only two points have a very high environmental impact, one located in the municipality of Cabo de Santo Agostinho, and another in the municipality of Olinda. It is concluded that there is a great need to implement an integrated management plan for CW in MRR, as well as greater monitoring by the basin committees.
