FRANKLIN, Tenn. -- State workers Friday went door to door in a Franklin neighborhood to see if dangerous chemicals from a nearby creek have contaminated any homes.

VIDEO: Pollution In Franklin Creek Could Affect Air Quality

Pollution floating in Liberty Creek near downtown Franklin appears to be getting worse and everyone is being warned to stay far away.

An environmental advocate said she has been watching chemicals seep up into the creek in three places.

“Where it bubbles up, it’s really obvious that it’s a petroleum type product because it’s oily, it bubbles to the surface and then it forms a slick,” said Harpeth Watershed Association member Pam David.

The chemicals include tolulene, acetone and xylene and all are considered toxic.

The chemicals are also feeding bacteria that are growing in clumps in the creek.

“There is nothing alive right now in that water,” David said.

Environmental officials said they are also concerned about what is in the air.

“Along with the concentrations in the water, there are fumes. So, they are monitoring the air quality in and around the seep,” said Ashley Holt of Tennessee Environment and Conservation.

Crews checked homes in the area Friday to see if any fumes were concentrated in anyone’s homes.

They also checked the storm sewer for toxic fumes.

“Well, it’s kind of scary. But we have known there is something here for several years because there’s been an odor here for quite a while,” said area resident Emily Cox.

Across the creek from Cox’s home is a company called is Egyptian Lacquer. The company uses some of the same chemicals that are seeping.

The firm said they have hired their own consultant to help determine the source of the pollution.

“Well, right now, we’re sampling the creek every day,” Holt said.

State officials said they plan to place warnings to keep people away from the seep.

No toxic fumes were found in any of the homes.

Egyptian Lacquer Company also agreed to shut down access from their chemical storage tanks to the underground lines.

It is unclear if the lacquer company is responsible for the pollution.

Officials said that whoever is responsible will also be responsible for the cleanup.
