The wreckage and debris from Tropical Storm Iselle is raising concern about pollution of Big Island natural tide pools and ponds in Kapoho.
"We're really worried about the tide and that's what the county is trying to find out as well," said Marz Holman, a Vacationland homeowner.
Hawaii County will be partnering with the University of Hawaii Hilo and the state Department of Health to test the water this week.
"Going forward it's looking at what might be biological matter that's in the water as far as if there was any breach near the cesspools and septic systems," said Darryl Oliveira of the Hawaii County Civil Defense.
The tests will also check to see if any of the damaged homes and debris in the now murky ponds are contaminating the water, which could in turn hurt the eco system and bio life in the area.
"It's looking at what kind of chemicals might be present post impact with any household debris, or if you can picture, there's containers let's say petroleum products, etc. and [figuring out] whether there's any effluent coming out from the ponds that currently have a lot of debris and seeing if that is seeping into the ocean and coastal areas," said Oliveira.
So until health officials know what's in the water, it's another speed bump for residents anxious to clean up and recover from Iselle's aftermath.
"We want to make sure that if there are any concerns with the clean-up, that we provide the appropriate information to help people do what's safe to keep themselves safe as they do the clean-up whether it be residents or any volunteers down there," said Oliveira.
The Department of Health says they have tested the tide pools in the marine conservation areas. Those came back normal for bacteria contamination.
The county hopes to start testing other waters this week.
