PUBLIC HEALTH ASSESSMENT

DEL MONTE CORPORATION
(OAHU PLANTATION)
KUNIA, HONOLULU COUNTY, HAWAII

CONCLUSIONS

Based on the available information, Agency for Toxic Substances and Disease Registry (ATSDR) concludes that the people of Kunia were not exposed to significant levels of ethylene dibromide and 1,2-dibromo-3-chloropropane in their drinking water. Therefore, we do not anticipate that the people who drank the Kunia well water will have any adverse health effects. In accordance with the ATSDR Public Health Assessment Guidance Manual, ATSDR has classified the Del Monte Oahu Plantation National Priorities List (NPL) site as a "No Apparent Public Health Hazard" for past and current conditions.

Multiple groundwater samples have been taken only from three wells in the upper aquifer and one well in the Waipahu Basal Aquifer. Therefore, total extent of groundwater contamination originating from the Del Monte Oahu Plantation NPL site has not been determined.

Because the total extent of groundwater contamination has not been determined, it is not possible for ATSDR to determine whether site-related contaminants can migrate into drinking water wells downgradient at levels of public health concern from the Del Monte Oahu Plantation NPL site. In accordance with the ATSDR Public Health Assessment Guidance Manual, ATSDR has classified the Del Monte Oahu Plantation National Priorities List site as an "Indeterminate Public Health Hazard" for future conditions.


RECOMMENDATIONS

  1. The total extent of groundwater contamination in the upper and Waipahu Basal aquifers should be determined.
  2. In addition to ethylene dibromide and 1,2-dibromo-3-chloropropane, environmental samples from the Del Monte Oahu Plantation National Priorities List (NPL) site should also be analyzed for the other pesticides used at the Del Monte Oahu Plantation and for substances on the U.S. Environmental Protection Agency Target Compound List.
  3. Appropriate quality assurance and quality control procedures should be conducted for any future environmental sampling at the Del Monte Oahu Plantation NPL site.
  4. Drinking water wells downgradient from the Del Monte Oahu Plantation NPL site should be monitored annually for site-related contaminants.

The Del Monte Oahu Plantation NPL site, Honolulu County, Hawaii, has been evaluated by the ATSDR Health Activities Recommendation Panel (HARP) to determine what future health activities are recommended at this site. Because ATSDR concludes that the people of Kunia were not exposed to significant levels of site-related contaminants and does not anticipate that the people who drank the Kunia well water will have adverse health effects, this site is not being considered for follow-up health activities at this time. During the public comment period of this public health assessment, ATSDR provided health education during the Public Comment Period to explain the Agency's findings. However, if data suggesting that human exposure to hazardous substances at levels of public health concern is currently occurring become available, ATSDR will reevaluate this site for any indicated follow up.


PUBLIC HEALTH ACTIONS

The Public Health Action Plan (PHAP) for the Del Monte Oahu Plantation National Priorities List (NPL) site is a description of actions the Agency for Toxic Substances and Disease Registry (ATSDR), the U.S. Environmental Protection Agency (EPA), and the Hawaii Department of Health (HDOH) will take at the site. The purpose of the PHAP is to ensure that this public health assessment identifies public health hazards and includes a plan of action to stop or prevent harm to people that can be caused by their exposure to hazardous substances in the environment. ATSDR, EPA and HDOH are committed to this plan and will ensure that it is carried out.

A. Public Health Actions Taken

The owners of the Del Monte Oahu Plantation discontinued using the Kunia well (United States Geological Survey [USGS] number 2703-01) immediately after it was determined the well was contaminated with ethylene dibromide (EDB) and 1,2-dibromo-3-chloropropane (DBCP). The plantation owners are providing Kunia with drinking water that is not contaminated with hazardous substances.

The Safe Drinking Water Branch, HDOH, monitors all state drinking water wells that serve 25 or more individuals. Tests for DBCP and EDB are routinely conducted.

ATSDR provided health education during the Public Comment Period of this public health assessment.


B. Public Health Actions Planned

EPA and HDOH will assure that any downgradient wells are monitored annually for site-related contaminants. In addition, EPA and HDOH will assure that future environmental sampling and analysis at the Del Monte Oahu Plantation NPL site will be conducted in accordance with EPA sampling and analysis protocols.

EPA and HDOH will update ATSDR on any activities at the Del Monte Oahu Plantation NPL site.
