"Elk River Leak Included Another Chemical"

"CHARLESTON, W.Va. -- Federal and state investigators learned Tuesday that an additional chemical that wasn't previously identified was in the tank that leaked Jan. 9 at the Freedom Industries tank farm, just upstream from West Virginia American Water's regional drinking water intake."

"The company told investigators that the Crude MCHM that leaked also contained a product called 'PPH,' according to state and federal officials.

State officials said late Tuesday that, after consulting with West Virginia American Water Co., they believe the water company's Elk River plant would likely have removed the chemical from drinking water during its normal treatment process. Additional testing of some of the original water samples from the first days after the incident is being conducted to confirm that, officials said."
