Abstract

The quantitative and qualitative assurance of the water shortage is one of the major challenges of the near future. This study is focused on the current and perspective plan adopted in the management of clean water sources and the quality of wastewater discharged from the local treatment plant of urban agglomerations and surrounding villages, with polluting potential generated by agro-zootechnical households and food processing companies. The research consisted of the analysis of some public data related to the monitoring and management of drinking water and wastewater during the year 2021. Six microbiological parameters and nineteen physicochemical parameters were evaluated in the case of drinking water, respectively the level of ammonium and suspended matter for the discharged wastewater from the sewage treatment plant.In carrying out laboratory analyses, the use of standardized methods was resorted to, and the analysis bulletins included the allowed values and the limit of quantification for the methods used. Data processing allowed differentiation of non-compliant tests and calculation of the degree of compliance. At the same time,the duration of water interruption was also evaluated (the quantification was made in days and the number of hours), and the effectiveness of the measures imposed by the authorities in the field, respectively the degree of remediation of technical problems that occurred at the water treatment plant during the period under study. Non-compliant tests were in alower proportion (0.34%), compared to compliant ones (99.66%). The values recorded in the case of the used water at the discharge revealed elevated exceedances of ammonium and suspended matter parameters, which confirmed the advanced stage of wear and the need to replace it with a new one, using zeolite as a sorbent. The major polluting impact of agro-zootechnical and food industry activities on surface waters in the area and the environment in general was also argued.
