People who were affected by the Navy’s petroleum contamination of Oahu’s drinking water are being encouraged to participate in a follow-up survey conducted by state and federal health agencies.

A previous survey conducted in January and February found that some 2,000 people reported physical and mental health impacts associated with the crisis, including 17 hospitalizations.

The new survey will evaluate “ongoing public health impacts, water usage, and attitudes toward the water system,” according to a Hawaii Department of Health press release.

The voluntary survey takes 20 to 30 minutes and is open to anyone who was served by the Navy water system from Nov. 20, 2021 through March 18. DOH said the identities of survey takers will be kept confidential.

“Jet fuel contamination of a drinking water system on this scale is unprecedented,” DOH State Toxicologist Diana Felton said in a statement. “This follow-up assessment will further the understanding of how the contamination impacted the health of impacted individuals and inform our public health response.”
