Crews will test the water at a campground where nine people got sick after going for a swim.
People were swimming at a pool at the Seaport RV Resort on Campground Road when nine people came down with symptoms, Old Mystic Fire Chief Ken Richards Jr. said.
Six of them were sent to hospital after possible chemical exposure while swimming in a pool at a campground in Old Mystic on Tuesday afternoon.
Those symptoms included itchy throats, vomiting and dizziness.
Six people were rushed to Lawrence & Memorial Hospital, the fire chief said. Three people were treated at the scene and refused to be transported to the hospital. Eight of the victims are children between the ages of 3 and 13.
None of the symptoms are considered to be life threatening.
The fire chief said these people could have been exposed to chemicals while in the water.
Campground Road was closed due to the police investigation. Department of Energy and Environmental Protection assisted in the investigation, and said
Firefighters tested the water shortly after they arrived and didn't discover any issues, but DEEP performed further tests.
DEEP officials said "staff did not detect any gaseous odors or any obvious issues with the water in the pool and have now cleared the scene."
The pool at Seaport RV Resort was closed for the investigation.
It will only reopen on Wednesday if the water is deemed safe.
