10.0 DATA QUALITY ASSURANCE AND QUALITY CONTROL

The State of Hawai`i Department of Health (HDOH) Hazard Evaluation and Emergency Response Office (HEER Office) regards the quality of data as crucial to proper site characterization and evaluation of potential environmental hazards at a site. Data must be of sufficient quality to ensure that the overall site assessment objectives are met using the systematic planning approach (see Section 3). Ensuring that data is of sufficient quality begins during the initial planning and development of site investigation objectives and continues throughout the investigation to the final assessment of data quality. The HEER Office also regards evaluation of the suitability and usability of data as essential during both the site investigation and data quality documentation process.

The quality assurance and quality control (QA/QC) process should also be viewed as an approach to:

  1. Ensure that site characterization data are adequate to accurately define site impacts and evaluate potential environmental hazards
  2. Maximize the potential that any remedial actions at a site will be correctly selected
  3. Ensure that site management decisions are arrived at with the correct information

Not devoting proper time and resources to QA/QC at any stage of investigation may result in uncertainly as to whether conclusions or actions are sufficiently protective of human health and the environment; this deficiency may be compounded by the need to make up for wasted time and resources.
