“Arkema needs to make sure that whatever chemicals entered the air, whatever whatever from the water thanks overflowed into the water supply, they need to ensure that now it’s clean and safe for the residents,” said attorney Mo Aziz.

The company pushed back against the “unfounded” legal claims.

“Liberty County’s lawsuit unfairly accuses Arkema and its employees of wrongdoing and contains misinformation that could unnecessarily alarm residents,” the company said in a statement. “The County and its residents could not have been seriously injured by Arkema’s releases because all monitoring and testing results show no exceedances of Texas residential environmental standards in soil, surface water, ash or drinking water occurred at off-site properties.”
