All through the course of the evaluation, the outcomes obtained from all samples collected point out the water continues to fulfill all state and federal consuming water requirements. Low-level detections of whole petroleum hydrocarbons have been reported for some samples collected from fixtures and water heaters from inside properties, in addition to related hearth hydrants throughout the JBPHH water distribution system. A chromatogram evaluation of pattern outcomes (fingerprinting) revealed no carbon chain sample matching jet propellant 5 (JP-5), indicating the absence of JP-5 within the water. The report concluded that detections of petroleum hydrocarbons should not distinctive to residential premise plumbing (e.g. water heaters) and that further investigation is warranted.
To that finish, upon conclusion of its premise plumbing evaluation, the Navy initiated a root trigger evaluation to determine the supply of detections of whole petroleum hydrocarbons. In late January 2024, the Navy convened a bunch of consuming water consultants – or ‘swarm group’ – together with officers from the Hawaii Division of Well being (DOH) and Environmental Safety Company (EPA). Consultants and the regulatory companies proceed to assessment the group’s information assortment and evaluation.
The premise plumbing evaluation additionally recognized a number of suggestions which the Navy has taken for motion, particularly together with an expanded water high quality investigation functionality. The Navy can also be implementing different actions, to incorporate: continued and expanded use of the chromatogram evaluation; further investigation of potential lab contamination; assessment of laboratory evaluation procedures; split-sampling evaluation by alternate, EPA-certified laboratories; and analysis of the JBPHH consuming water distribution system infrastructure, operation, upkeep and repairs to determine potential sources of petroleum hydrocarbons.
The Navy continues to intently coordinate with the DOH and the EPA to deal with issues and can proceed to share findings from ongoing and future efforts and is dedicated to figuring out the reason for detections.
