Ecoanalytical control and monitoring of the water quality
in Samara municipality

Summary

In Samara municipality the industrial control of natural and drinking water quality is carried out by an accredited water quality testing center. The control is executed according to the program developed by «Samarskie Kommunal’nye Sistemy» LLC and approved by the Samara Area Department of the Federal Service for Supervision of Consumers Protection and Welfare. The control is performed at all the stages of water treatment beginning from the water source to water posts in the distribution network. Monitoring the water conditions in the surface water source provides for controlling the treatment facilities operating mode and selecting the required chemical dosages at every stage of the treatment process. Industrial quality control of the wastewater coming to the municipal treatment facilities and of the effluent is carried out by a chemical and bacteriological accredited testing laboratory at every process unit from the receiving chamber to the discharge to the Saratov water reservoir (before the discharge the effluent is biologically tested for acute toxicity). Sludge generated in the process of wastewater treatment is tested at every stage for physical, chemical microbiological, parasitological, toxicological and radiological parameters. The efficiency of the biological treatment facilities is evaluated basing on the results of hydrobiological analysis of activated sludge. The laboratory facilities and continuous renovation of the basic infrastructure are described. Special attention is paid to the laboratory staff development and achievements.
