Hawaiʻi health department officials Thursday descended upon the Kapilina Beach Homes development in West Oʻahu to collect water samples for testing.
The housing development is on former Navy land and still uses water from its distribution system.
Some residents have complained about physical ailments similar to those suffered by residents in military housing near Joint Base Pearl Harbor-Hickam.
The Navy shut down two of its water shafts that provide water to some 93,000 people after petroleum contamination was detected.
The Navy and Department of Health say they're still investigating the source of the contamination.
On Wednesday, the Navy said it detected diesel fuel in a second water source, the Aiea-Halawa shaft — but appeared to backtrack later, saying the sample came from a source that was not in use.
The Honolulu Board of Water Supply says it has received verbal confirmation that water from the BWS Halawa shaft is uncontaminated by petroleum.
The back and forth between the Navy and entities like the state Department of Health caught the eye of U.S. Sen. Brian Schatz. He released a statement calling for the federal Environmental Protection Agency to be the lead agency for the collection, testing and analysis of water samples.
Schatz said Hawaiʻi residents cannot stand another day of disagreements between the Navy and government officials over whether the water is safe to drink.
