West Virginia American Water said June 12 the process of replacing its carbon filters is complete, leaving behind no detection of crude MCHM.

The water company told customers it would change the filters a little over one week after the June 9 spill of the coal-cleaning chemical contaminated the drinking water for 300,000 residents in the surrounding Kanawha Valley.

WVAW said its Granular Activated Carbon filter change-out project at the Kanawha Valley Water Treatment Plant is complete.

According to the water company, test results received June 12 have allowed operators to put the last newly changed filters back in service, completing the project of removing nearly one million pounds of activated carbon from 16 filters, replacing it with virgin carbon, conditioning the filters and testing the water to ensure that it meets all drinking water standards and that no trace amounts of MCHM are detected.

Jeff McIntyre, President of WVAW, said the company has been committed to customers to change the filters after the spill occurred.

“We committed to our customers 10 days after the spill that we would change the filter material as soon as conditions allowed to ensure customer confidence in the quality of the water that we deliver 24/7 to their homes and businesses,” McIntyre said. “Restoring full water service and full confidence in our water was not just our job — it was our promise to our neighbors and our families in the communities we serve because this community is our home too.”

A total of 64 filtered water samples from newly changed filters, along with 26 samples from other various stages of the water treatment process, were sent to Eurofins Lancaster Laboratories, Inc. Testing was performed at the lowest existing detection level of any laboratory and confirmed the non-detection of MCHM. West Virginia American Water is announcing project completion today based on receipt of the final test results, but all water leaving the treatment plant has been filtered through new filter material since May 23 when the last filters were taken out of service for carbon replacement. All 16 filters are now in service with new filter material.
