Water Testing Results Released for Pearl City Peninsula (Zone A1)

24 January 2022
JOINT BASE PEARL HARBOR-HICKAM, Hawaii - The U.S. Navy released system flushing data validated by the Interagency Drinking Water System Team (IDWST) for the Pearl City Peninsula (Zone A1) today.

“The data we are releasing today demonstrates that the testing is working as designed,” said Karl Banks, one of several drinking water experts from the U.S. Environmental Protection Agency working as part of the IDWST. “This flushing, testing, and evaluation process will ensure that safe drinking water is restored to the residents and workers at JBPHH.”

A summary of the lab results can be found here and the complete lab results can be found here.

Samples met Environmental Protection Agency (EPA) and Hawaii Department of Health (DOH) criteria for Total Petroleum Hydrocarbons (TPH) and safe drinking water standards. Based on these test results, flushing teams have been conducting residential and non-residential flushing after residents were notified. The residential and non-residential building flushing data will be made available once it has been validated and reviewed by the IDWST.

The following information is provided to help interpret the data:

  • The Total Petroleum Hydrocarbons (TPH) test is one of the most common tests performed by certified laboratories.
  • Maximum Contaminant Levels (MCLs) are established by the EPA and are the maximum permissible level of contaminants in water which is delivered to any user of a public water system.
  • Environmental Action Levels (EALs) are established by the Hawaii DOH and are concentrations of contaminants in drinking water and other media (e.g., soil, soil gas, and groundwater) below which the contaminants are assumed to not pose a significant threat to human health or the environment. Exceeding the Tier 1 EAL does not necessarily indicate that contamination at the site poses environmental hazards but generally warrants additional investigation.
  • All values are in micrograms per liter (µg/L) which is equal to parts per billion (PPB).
  • The Method Detection Limit (MDL) is the lowest concentration at which an analyte (chemical subject that is being analyzed) can be detected in a sample.
