Quality control plays a vital role in Wastewater Monitoring and covers multiple working procedures. This article also presents quality control solutions for wastewater analysis procedures.
To date, numerous cities have set up Wastewater Monitoring institutions. Their core function is to conduct real-time monitoring on treated sewage discharged from various urban pollution sources, so as to check whether the discharged water meets discharge standards and protect surrounding water resources. Wastewater monitoring quality control provides comprehensive quality assurance for the whole monitoring work and guarantees accurate and valid monitoring data. Errors occurring in any link of the workflow may lead to unreliable data and render wastewater monitoring ineffective. Quality assurance for environmental monitoring serves as a core foundation for data collection and water environment compliance assessment. The following elaborates on quality control procedures and corresponding countermeasures for wastewater monitoring and analysis.
Core Tasks of Wastewater Monitoring Quality Control
1.Quality control during wastewater sampling
2.Quality control for sample preservation and transportation
3.Quality control of monitoring and analysis conditions
a) Standardization of wastewater monitoring and analysis methods
b) Quality control using certified reference materials
c) Control of blank sample measurement and blank control charts
4.Quality review of water quality monitoring data
Quality Control Measures for Wastewater Monitoring and Analysis
1.Implement standardized management of the whole monitoring workflow
Unstandardized management of sampling, sample preservation, transportation and other procedures will interfere with the accuracy of subsequent monitoring results. All sample handling operations shall be carried out in strict accordance with relevant technical specifications to ensure the credibility of monitoring data.
2.Conduct regular measurement and inspection of procedural blank values
Excessive deviation of blank values indicates defects in certain monitoring links. Laboratory staff shall promptly review and troubleshoot relevant procedures to maintain stable and controllable analysis conditions.
In summary, to guarantee effective Wastewater Monitoring Quality control, practitioners shall inspect every single workflow link and rectify existing issues accordingly.
