Department of Energy and Environmental Protection and police are investigating after hazardous materials were found in the basement of the home in Waterford on Tuesday morning.
Along with the DEEP Emergency Response Team, Connecticut State Police Emergency Services Unit responded to 13 Prindiville Ave. around 9:30 a.m. The Federal Bureau of Investigation and state police are assisting in the investigation.
Police said it's an "ongoing investigation" and there was no danger to the public. However, neighbors said they were a little uneasy because of the investigators' prolonged presence in the area.
"To see all this commotion in a residential area, this is quiet," said neighbor Brian Hanrahan. "I hope whatever's here can be cleaned up today."
Officials said they found liquid and powder materials in the home that will be sent to the state crime lab for further testing, which could take weeks.
Police said the materials are considered to be hazardous, but police don't believe it is illegal to possess the substances on their own. However, combining the materials could be illegal or dangerous.
The area was cordoned off by police along with the Waterford Fire Service. Police said it remains an "active scene."
DEEP spokesman said they were assisting with identification of materials found in the home.
"Basically the call came from an anonymous tip," Waterford Police Lt. Stephen Bellos said. "We could not identify the materials so we called ESU and DEEP to help us with that."
Investigators said it's unclear if any criminal charges will be filed, but it's certainly possible.
