KANAWHA VALLEY CARBON CHANGE-OUT PROJECT UPDATE: Our activated carbon filter change-out project at the Kanawha Valley water treatment plant is halfway complete. Test results received yesterday afternoon allowed operators to put two more newly changed filters back in service, bringing the total number of filters changed out and returned to service to eight. Water samples taken from all filters changed out so far showed no detection of MCHM at the lowest available laboratory detection level. Work has continued this week in the second 8-filter wing with carbon already removed from two more filters and virgin carbon in its place by later today. Prior to being put back into service, all filters are conditioned, monitored and tested to meet all drinking water standards. We 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 approximately nine weeks, subject to operational conditions. The Kanawha Valley plant continues to produce water that meets all drinking water standards and CDC guidance. Water samples continue to be taken every four hours and tested for MCHM. All samples have been non-detect at two ppb since late February.
