WVAM Says MCHM Not Detected After Carbon Filters Changed
West Virginia American Water said new tests show no signs of MCHM from water filtered through two newly replaced carbon filters.
The company began changing out the 16 activated carbon filters in the Charleston plant on April 1.
In a release this Monday, WVAM said 16 water samples taken throughout the filtration process at that location returned non-detect levels of MCHM.
The results came from Eurofins Lancaster Laboratories, Inc. in Lancaster, Pa., which WVAM said is testing the water at the 0.38 parts per billion level.
The company said they have shared the results with the West Virginia National Guard, the West Virginia Bureau for Public Health and the WVTAP team and will now put the changed filters back into operation.
So far, they have completed the change out of two of the 16 carbon filters. When the process began, the company said it would take months to completely replace all of the filters.
WVAM said they will test the water for MCHM throughout the filtration process after each set of filters is replaced.
