The death of hundreds of fish in Aiea has sparked a health department investigation.
Officials gave KHON2 new information after a viewer alerted us to the problem through the Report It feature on our website.
Health officials say they found more than 500 dead fish along a canal by a bike path.
“The species that we found. Some were native. But primarily guppies and talapia,” said environmentalist Carroll Cox.
Water testing confirmed the presence of a solvent or cleaning solution in the canal.
So now officials are working to find out who is responsible by checking storm drains and talking to nearby businesses.
