CHARLESTON, W.Va. — The state Bureau of Public Health and West Virginia American Water Company dismissed comments made Wednesday by a Marshall University professor who said formaldehyde has been found in the water in downtown Charleston.

Scott Simonton, a professor and vice chairman of the West Virginia Environmental Quality Board, warned state lawmakers the cancer-causing chemical is a breakdown product of MCHM, the chemical that leaked into the Elk River from the Freedom Industries site in Charleston on Jan. 9.

“Formaldehyde is a known human carcinogen and where it’s most toxic is inhalation,” Simonton said. “I can guarantee you the citizens of this valley are at least in some instances breathing formaldehyde. Taking a hot shower, this stuff is breaking down, formaldehyde, in the shower, in the water system and they are inhaling it.”

West Virginia American Water issued a statement Wednesday night saying Simonton was “misleading and irresponsible” to voice his opinion without all of the facts.

Dr. Letitia Tierney, commissioner of the state Bureau of Public Health, also shot down Simonton’s comments as “totally unfounded and does not speak to the health and safety of West Virginians.”

Simonton said the formaldehyde situation is a “huge cause for concern” and points toward support of long-term monitoring of residents in the water emergency area affected by Freedom Industries. The spill touched off a water emergency that has impacted approximately 300,000 state residents in nine counties.

Simonton said he found formaldehyde while testing the water at a Charleston restaurant in the days after the water contamination. He was testing for a law firm.

West Virginia American Water’s statement also said:

“Procedures for water analysis are carefully prescribed, outlined and certified. West Virginia American Water will continue working with governmental health and environmental professionals and, in conjunction with these professionals, we and public health agencies will make public any reliable, scientifically sound information relating to risks to public health, if any.”

Professor Simonton told lawmakers he was “a little freaked out” by his test results.

“Somebody said ‘just because you can smell it doesn’t mean it’s bad for you.’ They don’t have that data. Nobody has that data,” Simonton said. “We don’t know the inhalation risks on MCHM. We don’t know what the odor threat threshold is on MCHM.”

West Virginia DEP Secretary Randy Huffman told the Charleston Daily Mail Wednesday he was not aware of formaldehyde being linked to the water emergency.

“That doesn’t mean there’s not, we’re just not aware of it,” Huffman told the newspaper. “I absolutely don’t want to downplay the significance for the potential of formaldehyde in anyway. If it’s there, it needs to be dealt with.”

Simonton told lawmakers the bottom line is there’s so much not known about MCHM and how it reacts in the environment.

“This is a population that has been exposed and we don’t know to what extent,” he said.
