    18              Appendix B: Data quality objectives (DQO) process

18.1          Introduction
The DQO process is a seven-step iterative planning approach that is used to define the type, quantity and quality of data needed to inform decisions relating to the environmental condition of a site. The summary of the process below is adapted from US EPA (2006a) and NSW DEC (2006).

The DQO process should commence before any investigative work starts, with the timing for various stages of the project being clearly understood by all parties. It is useful to apply the process initially at a project level to determine the overall project requirements and then modified as required for specific investigation activities.

The seven steps in the DQO process are:
    Step 1: State the problem
    Step 2: Identify the decision/goal of the study
    Step 3: Identify the information inputs
    Step 4: Define the boundaries of the study
    Step 5: Develop the analytical approach
    Step 6: Specify performance or acceptance criteria
    Step 7: Develop the plan for obtaining data

18.2          The seven-step DQO process

    18.2.1      Step 1: State the problem
The first step involves summarising the contamination problem that will require new environmental data and identifying the resources available to resolve the problem. A preliminary CSM will be required to complete this step. The matters to consider at this stage include:
    * the objective of the proposed investigation, noting that the ability to meet objectives may be limited by constraints such as time, resources, climatic conditions and access restrictions
    * the possible content of a problem statement that gives a brief summary of the contamination issue(s) at the site that is to be addressed in the project
    * the reason the project is being undertaken
