ASSESSMENT OF NEGATIVE SOCIO-ENVIRONMENTAL IMPACTS CAUSED BY THE WASTEWATER TREATMENT PLANT OF CHIMOIO PROVINCIAL HOSPITAL

Abstract

The objective of this study was to evaluate the negative socio-environmental impacts caused by the Wastewater Treatment Plant of the Chimoio Provincial Hospital. The study was carried out between February and May of the year 2024. To materialize the study, the exploratory research methodology was used, implemented through a case study, using for this purpose the resources of bibliographical research, identification of points for collecting water samples and subsequent laboratory analysis of the parameters (physical, chemical and microbiological), as well as diagnosis of the current socio-environmental situation of the neighborhood with the WWTP operating. The environmental impact assessment (EIA) itself was carried out using the Leopold matrix method. The results obtained in laboratory analyzes of physical, chemical and microbiological parameters showed that the effluent treatment carried out by the WWTP has not been efficient, this is because most of the values ​​obtained in laboratory analyzes of samples collected in the field do not comply with the established in CONAMA Resolution 357/05. Therefore, the results of the analyzes of COD, Nitrate concentration, MPN of total coliforms and other parameters measured in the samples were outside the maximum4and minimum limits established by the standard. Finally, after carrying out the environmental impact assessment (EIA), it was found that the HPC wastewater treatment activity carried out by the ETAR in the Chinfura neighborhood generates significant environmental impacts and deserves attention from the entities responsible for it.
