SUMMARY:
The laundries of the Textile Hub located in Caruaru, Brazil, produce a large amount of effluents per day. These effluents, once discharged into the Ipojuca River and its tributaries, are influencing the accumulation of compounds with a high pollutant load in the sediment of the water bodies. This study aims to diagnose the health of the Ipojuca River in the Textile Hub section through monitoring and environmental diagnosis of the quality of soils and surface sediments. The sampling points were defined based on an exploratory assessment of the quality of surface sediments to identify atypical areas enriched with metals. The study was conducted through 10 sediment collection events after surveying the registered laundries in the Caruaru Laundry Association (ALC), located in a section of the Ipojuca River in the urban center of Caruaru, Brazil. The results obtained from the study indicate that there are levels above the established limits by environmental agencies CONAMA and USEPA for pollutant heavy metals such as As, Cr, Cu, Ni, Pb, and Zn. Copper (Cu) and Zinc (Zn) concentrations in section I-08 were particularly high, mainly due to the proximity to Salgado Creek, where several textile laundries, commercial activities, and domestic sewage discharge are located. Therefore, it was possible to identify through the analysis that these factors contribute significantly to the intense contamination in this region, as the laundry effluents are discharged directly into the environment. One of the main conclusions was the importance of implementing pollution containment measures at the confluence of Salgado Creek and the Ipojuca River to reduce the transport of sediment contaminated with heavy metals to the river, which poses risks to human health. There is a need for preventive measures by public management to avoid environmental contamination.
