JOINT BASE PEARL HARBOR-HICKAM, Hawaii – The Navy, in coordination with the Hawaii Department of Health (DOH), has released the second month of long-term monitoring (LTM) drinking water data for Joint Base Pearl Harbor-Hickam (JBPHH) on the https://jbphh-safewaters.org website. Drinking water continues to meet U.S. EPA and DOH standards.
Summary reports and laboratory data for the second month of LTM sampling results for all 19 Navy water distribution system zones are now available, following a final review by the DOH. Since the Navy began long-term monitoring on March 22, there have been no detections of JP5 contamination in the Navy water system.
Under an interagency-approved flushing and sampling plan, the Navy water system is now in a two-year period of LTM. This includes testing about 7,800 more samples from roughly 55% of residences and other facilities on the system for more than 60 different contaminants.
Under the plan, the Navy is sampling 5% of homes and other buildings in each zone of the Navy water system for the first three months after the DOH amended that zone’s health advisory (a total of 15% in each zone after three months). After that, 40% of all homes and other buildings on the system will be sampled over the following 21 months. All schools, child development, and medical centers will be sampled regularly during each phase of the plan.
In addition to summary reports for each zone, specific sampling results for the homes and other buildings that were sampled are posted within each zone. Results are grouped by category, such as residences, other buildings, schools, and child development centers, and listed by street address.
Sampling locations for homes in each zone are chosen as a geographic representation of the zone, based on their location on the neighborhood distribution system. Different homes will be chosen during each phase to provide a good geographic spatial representation of homes sampled.
All results are validated to state and federal drinking water requirements, including the incident-specific parameters (ISPs) set by the DOH for the Navy water system.
Sample results are generally categorized as non-detect, detect, or exceed. If a sample exceeds action levels for contaminants, the resident or building point of contact will be personally notified and additional sampling will be performed.
