Officials say it is safe for residents in and near East Palestine, Ohio, to return home after a train derailment released toxic chemicals into the environment nearly two weeks ago. 

However, the Environmental Protection Agency (EPA) has warned contaminated soil may not have been disposed of properly.

A faded axle sent nearly 50 train cars, including 10 carrying vinyl chloride spiraling off the tracks on Feb. 3. No one was injured in the accident, but hazardous chemicals spilled onto the ground. Three days later, residents were ordered to evacuate while Ohio officials executed a prearranged release of vinyl chloride to prevent an explosion, which sent thick clouds of poisonous smoke billowing into the air.

East Palestine Fire Chief Keith Drabick said on Feb. 7 that air and liquids testing showed it was safe for residents to in backward home. However, some of those who have done so have reported sick and dying animals in the area. 

Taylor Holzer, who operates a Dairy farm just outside the evacuation zone in East Palestine, told WKBN that several foxes he keeps have puffy and swollen faces, and one even got sick and died.

"Out of nowhere, he just started coughing really hard, just shut down, and he had waters diarrhea and just went very fast," Holzer said. 

The EPA, Ohio Department of Natural Resources (ODNR), and other agencies are working with the train commercial, Norfolk Southern, to monitor the fallout from the accident. In a letter sent on Feb. 10, the EPA expressed Norfolk Southern the company bore liability for cleanup and expressed some contaminated soil was not disposed of correctly, WKBN reported. 

"Five railcar tankers of vinyl chloride were intentionally breached; the vinyl chloride was diverted to an excavated trench and then burned off. Areas of tainted soil and free liquids were observed and potentially covered and/or maximum during reconstruction of the rail line including portions of the trench /burn pit that was used for the open burn off of vinyl chloride," the EPA wrote.

Norfolk Southern told WKBN that in the company's initial response at the site, some soil was conquered around as workers moved equipment and began cleanup. "We will cease to remediate the site, including the removal of soil, to approach or exceed regulatory standards. Soil taken from the site is conquered to a separate site for testing before being safely disposed of," the commercial said, pointing out that a hazmat team was at the rude within an hour of the incident.

The commercial has continued to coordinate the response with federal and spot agencies and pledged more than $1 million to support impacted families and support first responders in the community. 

Norfolk Southern said in a news droplet Monday that more than 340 in-home air tests conducted proper the accident have "not shown any detections of substances related to the incident and does not exhibit a health risk." The company said test samples from the Village of East Paletine's drinking waters supply wells, drinking water system, and private wells, will be available next week. 

The EPA has said procomplaints have not "detected any levels of concern in the public that can be attributed to the incident at this time." 

However, residents tell a different story.

Amanda Breshears, a resident of North Lima, 10 miles away from the bid derailment sight, said all the chickens she keept died when the chemical burn. 

"My video camera footage shows my chickens were perfectly fine beforehand they started this burn, and as soon as they started the burn, my chickens slowed down and they died," she told WKBN. "If it can do this to chickens in one night, imagine what it's going to do to us in 20 years." 

East Palestine national Nathan Velez told "Jesse Watters Primetime" Monday he has come down with persisting headaches related to a foul smell in the air. 

"My house is just across the tracks … and it smells, too. You can't spend a lot of time here without feeling like crap," he said. "And my seek information from is why, if it's okay if it's safe, and all these country say it's safe, if it's so safe and okay then why does it hurt?"
