QA/QC program and that appropriate documentation is included in the assessment report:
    * replicate samples are split in the field and submitted to two separate laboratories in accordance with the requirements of Schedule B3
    * the sampling program includes assessment of all relevant environmental media, including soil, dust, surface water, groundwater, air, sediments and biota as appropriate
    * the sampling strategy is appropriate for the conditions at the site and the nature of the contamination, with the rationale for the strategy described in the assessment report and the sampling locations shown on a scaled site sampling plan
    * sample collection, handling and transportation procedures are documented and appropriate to meet the project DQOs
    * sampling is representative of site conditions, based on the selection of appropriate numbers of sampling points and of samples from each relevant strata and material types stated in a site sampling plan to meet the project DQOs
    * the field QA/QC plan  includes details of:
    -       the sampling team
    -       sampling method(s), including the actual methods employed for obtaining samples, type(s) of sample containers, order and degree of filling, preservation, labelling, logging, custody
    -       evidence of appropriate decontamination procedures carried out between sampling events
    -       completed logs for each sample collected, showing time, location, initials of sampler, duplicate locations, duplicate type, chemical analyses to be performed, site observations and weather conditions
    -       completed chain-of-custody documentation, identifying for each sample the name of the sampler, the nature of the sample, collection date, analyses to be performed, sample preservation method, departure time from the site and dispatch courier(s) and condition of samples at dispatch
    -       sample splitting techniques
    -       a statement of duplicate frequency for intra-laboratory and inter-laboratory duplicate samples and duplicate sample results
    -       field blank results
    -       background sample results
    -       rinsate sample results
    -       laboratory-prepared trip spike results for volatile analytes
    -       trip blank results
    -       field instrument calibration for instruments used on site.

19.8          Laboratory QA/QC
Environmental practitioners should ensure that the following issues are addressed in the laboratory QA/QC program and that appropriate documentation is included in the assessment report:
    * sample analyses use appropriate methodologies for each potential contaminant in the matrix in laboratories accredited for those analyses by the National Association of Testing Authorities (NATA) or an equivalent government-endorsed provider of accreditation for laboratories
    * appropriate practical quantitation limits (PQLs) for the chemicals of concern for use in the assessment of risk
    * a laboratory QA/QC plan with the following information:
    -       a copy of signed chain-of-custody forms acknowledging receipt date and time, conditions of samples on receipt and identity of samples included in shipments
  -       record of holding times and a comparison with method specifications
  -       analytical methods used
  -
