The state Department of Health is reviewing the first month's worth of data from the Navy’s two-year long-term monitoring of tap water in the Pearl Harbor area.

The continuous flushing and sampling plan of homes and businesses at Joint Base Pearl Harbor-Hickam is the result of jet fuel contamination of the water distribution system in November 2021.

Under the long-term plan, the Navy says it is sampling 5% of homes and other buildings in each zone of the Navy water system for the first three months after health officials declared that zone's water safe to drink. That's 15% of homes and buildings in each zone after three months.

Health officials declared the tap water safe to drink in all residential areas served by the Navy’s water system on March 18.

After the three-month period, 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, according to the Navy.

Final results typically take two to three weeks. Navy officials say the water testing is meant to ensure that those on the Navy’s distribution system are getting clean, safe water.

Results will be posted on
