CHARLESTON, W.Va, (WSAZ) -- West Virginia American Water has completed it's water carbon filter change-out project.
Test results, received by WVAW Thursday, show that there were no traces of MCHM in the water.
The results allowed operators to put the last, newly changed filters, back into the system.
The project to change all of the filters started back in April.
Crews removed one million pounds of activated carbon from 16 filters. The carbon was replaced to ensure that there were no levels of MCHM detected in the water.
In a news release, West Virginia American Water President Jeff McIntyre said, "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."
The chemical MCHM leaked from a storage tank at Freedom Industries on January 9th into the Elk River. The leak contaminated water for 300,000 West Virginia American Water customers.
