WV American Water: No trace of MCHM in treatment plant

Posted: Updated:

After some allegations of crude MCHM remaining in the water treatment plant, West Virginia American Water said in an April 14 news release samples from its filters have come back at non-detect levels.

The water company has been in the process of replacing its carbon filters in the Kanawha Valley water treatment plant, something it said it does, but had never done at the caliber with which it has proceeded with after the chemical spill that affected nine counties.

According to the water company, samples taken from the first two filters completed in the carbon change-out project showed "no detection of MCHM."

The company said in a statement 16 water samples from various stages in the water treatment process over a five hour period were tested ­­– sent to Eurofins Lancaster Laboratories, Inc. – a lab used by the WV TAP (West Virginia Testing Assessment Project) team brought into the state by Gov. Earl Ray Tomblin.

The test results have been shared with the West Virginia National Guard, West Virginia Bureau for Public Health and the WV TAP team.

"The filters are being put back into services, and testing will be conducted on filtered water following each subsequent filter change-out," according to a press release from the water company. "Testing is performed down to a .38 parts per billion reporting level, which is the lowest existing detection level to date."

West Virginia American Water began changing out nearly 500 tons of Granular Activated Carbon in the plant's 16 filters on April 1. The project is expected to take eight to nine weeks, subject to operational conditions.

The Kanawha Valley plant continues to produce water that meets all drinking water standards and CDC guidance.
