2. Read and interpret available site information, including site plan, bore locations, construction and history of sampling and monitoring
3. Confirm the sampling methods, locations, numbers and types of samples, and duration and frequency of sampling from workplace or client’s sampling plan
4. Check that all sampling and testing procedures are in accordance with client or workplace requirements, standards and guidelines
5. Prepare for groundwater sampling and monitoring
   • Identify site and sampling hazards and review workplace safety procedures
6. Liaise with relevant personnel to arrange site access and obtain all clearances and permits
7. Read and interpret field sampling procedures and sample preparation methods required for specific laboratory analyses
8. Select purging and sampling equipment and sampling conditions to achieve representative samples and preserve sample integrity during collection, storage and transit
9. Obtain and prepare all reagents, solutions, standards and blanks for field use
10. Select field test equipment and instruments and check operation and calibration in accordance with methods, procedures and manufacturer instructions
11. Assemble and stow all sampling equipment, field test equipment, materials, containers and safety equipment
12. Arrange suitable transport to, from and around site
13. Establish a well or bore for monitoring purposes
    • Confirm location of well or bore and groundwater monitoring requirements using site sampling and monitoring plan
14. Examine the well or bore area to identify possible hazards
15. Check proposed drilling and construction method will not cause contamination and that casing, drilling fluids and any other materials used in the bore are free of contaminants
16. Check powered and non-powered tools and sampling equipment are cleaned thoroughly before drilling commences
17. Check protective casings and screens are kept in their protective coverings prior to installation
18. Monitor process to accurately log samples and prevent their contamination
19. Conduct representative sampling of groundwater
    • Locate sampling locations and services at the site and identify possible hazards
20. Conduct sufficient measurements to accurately determine water level and bore depth
21. Record bore and environmental conditions and any atypical observations made during sampling that may impact on sample representativeness or integrity
22. Conduct purging in accordance with defined procedure or method, collect the waste and decontaminate the equipment used
23. Collect required representative samples and ensure all controls, blanks and replicate samples are correctly integrated into the sampling process
24. Record all information and label samples in accordance with chain of custody and traceability requirements
25. Filter and prepare samples to preserve their integrity for subsequent analysis
26. Secure and transport all samples back to base in accordance with workplace procedures and guidelines
27. Conduct field testing of groundwater
    • Assemble required monitoring instruments, equipment, and reagents and conduct pre-use checks in accordance with manufacturer instructions
28. Retrieve samples for designated field tests or locate established locations for in-situ testing
29. Set up, calibrate and operate equipment and instruments in accordance with test methods, procedures and manufacturer instructions
30. Take sufficient measurements of groundwater field parameters to obtain reliable data and in accordance with specified methods and procedures
31. Record all field observations and data and transfer accurately to workplace information database
32. Process and interpret groundwater data
    • Read and interpret test data noting atypical observations
33. Check calculated values are consistent with expectations
