11.0 HANDLING AND ANALYSIS OF SAMPLES

This section presents appropriate methods for containing, preserving, shipping, and analyzing environmental samples for projects conducted under the guidance of this Technical Guidance Manual (TGM). Proper handling and analysis of environmental samples is an essential step to collecting representative, defensible data and to achieving Data Quality Objectives (DQO). The Sampling and Analysis Plan (SAP) documents necessary sample handling and analysis procedures and should identify the matrix to be sampled, the type and volume of proposed sample containers, preservatives (if any), and the proposed analytical methods for each sampling event.

This section focuses on soil and groundwater samples collected as part of an environmental investigation, which are sent to a fixed laboratory for analysis. Mobile laboratories used for field analysis may also be employed during an environmental investigation, but the use of mobile laboratories should be carefully planned and documented in the SAP prior to field activities and analysis. The State of Hawai`i Department of Health (HDOH) Hazard Evaluation and Emergency Response Office (HEER Office) recommends the submittal of SAPs proposing the use of mobile laboratories for review prior to the initiation of sample collection activities.

During the collection, handling, and packing activities, personnel should use proper personal protective equipment (PPE). Typical PPE for use in sample collection, handling, and packing should include gloves and safety glasses, especially when employing chemical preservatives. Site-specific conditions may require the use of additional PPE (e.g., chemical protection clothing) based on the hazards present at the site, which should be documented in the site-specific Safety and Health Plan within the SAP.

Packing extra sample containers is recommended when planning fieldwork, in case additional sampling locations or areas are identified during execution of the fieldwork. Breakage, both prior to and after sample collection should be considered, particularly in light of challenges presented by remote field sites, as well as shipping requirements unique to performing investigations in Hawai`i.

Guidance is presented on the use of soil sampling equipment in Section 5 and on the use of groundwater or surface water sampling equipment in Section 6. A discussion of gas phase samples is not included in this section; guidance on handling and analysis of soil vapor or indoor air samples is presented in Section 7. Quality assurance/quality control (QA/QC) considerations, such as trip blanks and equipment rinsate blanks, are discussed in Section 10.
