In April 2014, the Hawaii Department of Health (HDOH), Hazard Evaluation and Emergency Response Office approved a “Cleanup Action Plan” for the former Kohala Sugar pesticide mixing site located outside the town of Hawi in North Kohala. See the “Whats New” entry below for July, 2014 for a fact sheet and detailed report on that Cleanup Action Plan. Subsequently, a more detailed “Cleanup Work Plan” was developed for implementation, and a Compliance Agreement was signed by HDOH and the landowner, Hawaii Island Community Development Corporation (HICDC) to ensure the work would be carried out as planned. See the links below for these two documents. Finally, a second public meeting regarding the site will be held in Kapaau on the evening of December 10, 2015 for HICDC and HDOH to help inform the community regarding the Cleanup Work Plan and the anticipated cleanup work schedule. See the Public Notice link below for more details on this public information meeting.

The HEER Office held two webinars this month on the use of discrete soil sample data in environmental investigations (refer to July, 2015 –Discrete Sample Variability Study Updates posting). An estimated 100 to 200 people joined in the webinars, including consultants and regulators from over other ten states as well as staff from several USEPA Regional offices.
The first webinar reviews the results of a field study of discrete soil sample variability carried out by the HEER office in 2013-2014 (see links in July posting). The second webinar describes how random variability both within discrete samples and between co-located samples limits reliability of the data for decision making and is the cause of failed confirmation samples, artificial “hot spots” and “cold spots” and overly drawn out environmental investigations. The webinar series concludes with an overview of Decision Unit and Multi Increment Sample investigation methods as a new set of tools specifically designed to address errors and inefficiencies in traditional, discrete sample investigation approaches.
PowerPoint slides and links to recordings of the presentations are posted to the HEER Office webinar page. Comments and suggestions for the webinars and the field study reports are welcome and can be sent to Roger Brewer at email@example.com. Updates to the study reports are anticipated in the spring of 2016.September 2015
The Hawaii Brownfields Forum #7 will be held Tuesday, Sept. 22, from 8:30 a.m. to 4 p.m. at the Neal Blaisdell Center.July, 2015 –Discrete Sample Variability Study Updates
The HEER office carried out a field study of potential discrete soil sample error in 2013 and 2014. The study evaluated the variability of contaminant concentrations both within discrete soil samples and between closely located sample points. The goal of this study was to provide a better understanding of the magnitude and sources of error associated with the use of discrete soil samples for the investigation and cleanup of contaminated properties.
Part 1 of the study presents the results of detailed, discrete soil sampling at three sites in Hawai´i previously known to be contaminated with arsenic (Study Site A), lead (Study Site B) and PCBs (Study Site C). The report, initially posted in October 2014, was updated in June 2015 to include additional analytical data as well as additional, statistical evaluation of the data. The updated report, including Excel files of data summary tables, can be downloaded from the links below.
Part 1: Summary of Field Data (pdf, 8,263KB)
Part 1: Appendix 1: Lab Reports (27 MB)
Part 1: Data Summary Tables (Excel, 5,464KB)
Part 2 of the study evaluates the sources of random variability of contaminant concentrations in discrete soil samples and discusses implications for the use of discrete soil sample data in environmental investigations. Topics discussed include: 1) Concepts of contaminant distribution in soil during preparation of environmental guidance in the 1980s and 1990s, 2) Nature and importance of “hot spots” versus “hot areas,” 3) Factors behind the need for multiple, remobilizations for site characterization, 4) Causes of “failed” confirmation samples following site remediation, 5) Artificial “hot spots” and “cold spots” in computer-generated, isoconcentration maps, and 6) Use of discrete sample data in environmental risk assessments, including the appropriateness of excluding “outlier” data in estimates of mean, contaminant concentrations. The report for Part 2 of the study can be downloaded from the following links:
Part 2: Implications (pdf, 11,572KB)
Part 2: Summary Tables (Excel, 249KB)
It is hoped that the results of this study will contribute to the current, re-evaluation of the reliability of discrete soil samples in environmental investigations and the need to move toward more technically defensible and efficient, incremental sampling methods. The reports will be updated and amended as needed in the future. Comments and suggestions are welcome and should be provided to Roger Brewer at firstname.lastname@example.org.
The Iwilei District encompasses approximately 315 acres of land in Honolulu and includes land owned privately and by the State of Hawaii. The Hazard Evaluation and Emergency Response (HEER) Office of the Hawaii Department of Health (HDOH) is overseeing remediation of potentially hazardous contaminants of concern that are present in soil, groundwater, and soil gas at various locations within the Iwilei District. Widespread, shallow petroleum contamination related to past releases from tank farms and pipelines is the primary concern, but metals and pesticides are also present in some areas.
To assist those who may become exposed to this contamination, the HEER office has developed a Programmatic Environmental Hazard Evaluation (EHE) /Environmental Hazard Management Plan (EHMP) document for the Iwilei District. This document details remedial measures and controls that are consistent with EHMPs implemented at other sites in Hawaii where contamination is present. No further investigation or remedial action is required at many of these sites, provided that long-term site management requirements in the EHMP are followed.
The document can be downloaded here: Programmatic Environmental Hazard Evaluation (EHE) /Environmental Hazard Management Plan (EHMP) document for the Iwilei District

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.
