CHARLESTON, W.Va. (June 13, 2014) – Initial test results show no detection of MCHM in water at the Kanawha Valley Water Treatment Plant following an overflow of a storm water collection trench at the Freedom Industries site. Samples of raw (river) and treated water taken at the plant this evening were tested for MCHM and show no detection. Additional analyses are being performed overnight.

Although it was reported that a small amount of water overflowed and no odor was reported at the site, our company is working closely with the Bureau for Public Health and the WVDEP. Since being notified of the overflow, there has been no indication of MCHM in the Elk River at our intake or anywhere in the treatment plant processes. Staff members are constantly monitoring the situation, and we took the following precautionary steps:

·        Plant operators increased the amount of Powdered Activated Carbon to provide additional absorptive capacity in the treatment process as a precaution.

·        Additional personnel were brought in to constantly monitor the raw water. River water is plumbed directly into the plant laboratory for monitoring, and operators are also heating samples of water to enhance the detection of any possible odors. There have been no odors detected and research performed since the January 9 spill indicates the odor of MCHM is detectable at very low concentrations below the safe level recommended by the CDC.

·        Additional staff was brought in to analyze water samples collected from both raw water and treated water. Additional test results should become available overnight.
