The Hazard Evaluation and Emergency Response Office has recently completed Part 1 of a two-part report evaluating discrete soil sampling variability at three contaminated sites in the state. The sites included investigations of lead and PCB contaminated sites on O‘ahu and an arsenic contaminated site on Hawai‘i Island. Part 1 summarizes data collected in the field investigations of contaminant variability, within individual discrete samples (intra-sample variability), within sets of discrete co-located samples around a single point (inter-sample variability), and for multi-increment samples. In addition to the detailed investigation findings, the report includes an initial interpretation of the data, implications for the reliability of discrete soil samples, and benefits of a multi-increment sampling approach for environmental investigations. Comments and suggestions regarding this report are welcome and should be provided to Roger Brewer at firstname.lastname@example.org. Part 2 (in preparation) will present a more detailed interpretation of the data and expand discussion on the potential for discrete sample decision error in site characterization, risk assessment, and remedial actions.

The Hawaii State Department of Health is providing the following information in response to an AP story posted by the Star Advertiser on April 30 (Biologist: Hanalei river, bay should be tested):
The concentrations of Arsenic, barium, chromium and lead reported by Hanalei River Heritage Foundation are within anticipated, natural background levels for the volcanic soils and related sediments of the Hawaiian Islands. The metals are naturally occurring, are tightly bound within minerals in the soil and are not toxic to humans or wildlife. The terrestrial and aquatic flora and fauna of Kaua‘i have lived with these metals since the island was created millions of years ago. They are similar to levels of metals in soil that would be found anywhere on the islands as well as much of the world, and are not related to manmade pollution. This is well documented in numerous reports over the past several decades, and summarized in the recent draft report “Hawaiian Islands Soil Metal Background Evaluation Report” prepared for the Hazard Evaluation and Emergency Response Office of the Department of Health. Hanalei River Heritage Foundation incorrectly compared the sediment (mud) data to regulatory standards for drinking water. These are completely unrelated standards and are not applicable to metals in soil or sediment.
If you need more information or have any questions, please contact the Site Discovery, Assessment & Response Supervisor Fenix Grange at 586-4249.May 2012 - The Hawaiian Islands Soil Metal Background Evaluation Report Now Available
The Hawaiian Islands background metals study has been in progress for several years and incorporates soil sample data from several technical and scientific sources. This report presents an evaluation of naturally occurring background concentrations of metals and related elements in the volcanic soils of the seven main Hawaiian islands (Kaua‘i, O‘ahu, Moloka‘i, Lana‘i, Maui, Kaho‘olawe, and Hawai‘i Island). Soil sample data were evaluated using cumulative probability plots, spatial and soil type distribution univariate plots, detailed spatial analysis, elemental association, geochemical analysis and professional judgment to estimate Hawai‘i-specific background concentration ranges. For more information on the report see the Cover Memo. View the full Hawaiian Islands Soil Metal Background Evaluation Report. View the summary table comparing background concentration ranges to HDOH Environmental Action Levels (EAL).
