Experience in Introduction of Systems of Quality Management and Ecological Management at the PU Zelenogradvodokanal

Summary

The process of introduction of the quality management system and ecological management system at the PU Zelenogradvodokanal of the Moscow State Unitary Enterprise Mosvodokanal (MSUE) is described. The department of quality management system has been organized at the enterprise; training of all employees has been provided. Certificates giving the right to carry out internal audits of a quality system have been issued as a result of training. Simultaneously with introduction of the quality management system it was decided to organize the ecological management system at the enterprise.

Establishment of Periodicity of Water Quality Monitoring with Due Regard for Measurement Inaccuracy

Summary

The periodical monitoring of quality of water with changeable characteristics is connected with sampling errors. Methods of accounting of these errors together with characteristics of measurement inaccuracy of polluting substances concentration for assessment of the risk of false conclusions about water compliance (or non-compliance) with specified requirements are offered. It is reasonable to establish the periodicity of measurements from the calculation of proportionality of sampling errors and meteorological inaccuracy specified by the certified measuring technique. The table of optimal periodicity of measurements depending on maximum permissible concentration of a polluting substance and changeability of its concentration in a water body as well as the scheme of prediction of water quality with a specified confidence level are offered for practical application.
