The inspection is based on sample records (field monitoring records, sample delivery and receipt records, field measurement records, laboratory analysis results records, etc.) and QC sample results ( blank sample, duplicate sample, standard sample,...);

b) Environmental monitoring and analysis results are only accepted after reviewing and evaluating the analysis results of QC samples to ensure reliability according to the laboratory's quality control criteria;

c) Statistical processing: based on the amount of sample and the content of the report, statistical processing can use different methods but at least there must be statistical data on the minimum value, value maximum value, average value, number of values ​​exceeding the standard;

d) Evaluate results: compare and contrast the monitoring results that have been checked and statistically processed with relevant standards and technical regulations.

b) Environmental analysis records include: analysis records, analysis results reports, original data stored in the memory of the analysis devices or backed up directly from the memory of the analysis devices ;

c) Records of quality assurance and field quality control and environmental analysis include, at a minimum, sampling records and field quality control sample results, equipment inspection results by standards in the field, quality control sample results in environmental analysis activities.

4. Data in field monitoring and environmental analysis activities must ensure completeness and consistency with field monitoring records and environmental analysis records; appropriate and consistent with the time, sampling location, time, and analysis parameters; suitable and consistent with monitoring methods and equipment; conforms to the acceptance criteria for measurement results.

5.
