Key Points of Implementation of the New Standards for Urban Drinking Water Quality Monitoring
This paper provides in-depth interpretation for the key sensitive issues during the implementation of the new standards and testing methods for urban drinking water quality monitoring.Guidance is given on the correct format for expressing indices,and templates are provided for the categories,frequency,and requirements of water quality testing,including source water monitoring.Important characteristic indices in method validation are explained,emphasizing the need for representative experimental results from independently prepared validation samples as objective evidence,moving away from simple repeated sample injection as a means of verification.In the context where quality control predominantly relies on blind sample tests or self-comparison,a correct approach is proposed,with statistical validation results serving as the optimal basis for quality control assessment.Suggestions are put forward to improving typical problems in inspection and testing reports are put forward.It is argued that method validation must meet statistical requirements,and quality control must be synchronized with sample testing,errors and problems should be found,cause analysis and corrective actions are implemented.
