Assessment of the effectiveness of the measures to improve the quality of drinking water in the Leningrad region

Introduction. To provide the population of the Leningrad Region with high-quality drinking water in 2019–2024, water treatment stations were installed in twenty settlements supplied with water from underground sources.

The purpose of the study. Assessment of the effectiveness of reducing the cumulative risk as a result of the installation of water treatment plants in settlements of the Leningrad region supplied from underground water sources.

Materials and methods. The study used the results of industrial control of water quality in centralized water supply systems of settlements in the Leningrad region for 2017–2024. An electronic database was formed, statistical data processing was carried out, and a list of controlled indices was analyzed. The values of the total risk and the effectiveness of measures were calculated using a computer software.

Results. A comprehensive assessment of the effectiveness was carried out for water treatment plants in 18 populated areas. The values ​​of the total risk before installation ranged from 0.067 to 0.368, after – from 0 to 0.159, the effectiveness of the water treatment plant installation ranged from 15.3% to 100%.

Limitation. The results of production control were used to assess the effectiveness measures to improve the quality of drinking water in the Leningrad region.

Conclusion. A comprehensive assessment of the effectiveness of measures to improve the quality of drinking water was conducted for 18 settlements in the Leningrad region. In 8 localities, the effectiveness of the event was 100%, in 2 localities – less than 20.0%. The use of a comprehensive efficiency assessment methodology in the planning and implementation of measures to improve the quality of drinking water makes it possible to justify their choice from the standpoint of minimizing the risk to public health.

Compliance with ethical standards. The study does not require the submission of a biomedical ethics committee opinion or other documents.
