In response to growing public concern, the commander of Joint Region Marianas, Rear Admiral Brett Mietus, says all military water sources on Guam are safe to drink.  JRM's page on Facebook states recent lab results show that all active military wells and surface water sources tested below Guam EPA's interim action level for dieldrin — that’s 0.2 parts per billion.

Of the nine tests conducted, seven returned “non-detect” results, meaning no trace of the chemical was found.

Two wells at Marine Corps Base Camp Blaz showed minimal levels — about ten times lower than the action limit — but officials stress the water remains safe for consumption. That’s because it’s mixed with water from five clean wells and the Guam Waterworks Authority system, further diluting any trace amounts.

Rear Admiral Mietus reaffirmed that protecting the health and safety of both civilians and military communities remains the top priority.

Quarterly results will continue to be reported to Guam EPA, and full data will be released in next year’s annual Water Quality Report.
