Scientific substantiation to updating drinking water quality monitoring programs

Introduction. The results of systematic drinking water quality laboratory tests are the most informative sources. Recommendations on the managing of drinking water quality monitoring were developed in 2020.

The purpose of the study was to substantiate methodological approaches to updating drinking water quality monitoring programs.

Materials and methods. The results of drinking water quality laboratory tests in the Murmansk region, conducted in 2021 in accordance with the monitoring program, were used. The results were analyzed for compliance with the recommendations of the drinking water quality monitoring program. An assessment of the compliance of the results of laboratory studies with hygienic standards and public health risk.

Results. In Monchegorsk, the drinking water quality was studied at nine control points according to sanitary-chemical, microbiological, and parasitological indicators. The multiplicity of studies per year ranged from 1 to 12 studies. The quality of drinking water in Monchegorsk corresponded to hygienic standards, with the exception of single excesses in the content of chlorine residual free and colour.

Limitations. When conducting the study, the results of the monitoring were used only for 2021, the results of drinking water quality production control were not taken into account.

Conclusion. To carry out an objective drinking water quality assessment, it is necessary to update the existing programs of monitoring its quality in the settlements of the Murmansk region carried out within the framework of the social hygienic monitoring (SHM).
