Moure-Eraso said that that is the nature of his agency.
"We contact them and say, 'This is what we recommend' and we write letters to them and say, 'What are your actions about this,'" Moure-Eraso said. "The power that we have is to say 'It's acceptable' or 'It's unacceptable.'
"We go to people like your newspaper and say, 'Look, we make these recommendations, which are public recommendations, and they have to be acted on.'"
Delegate Mike Manypenny asked if the CSB's three visits to the region in five years meant that there was a "systemic problem" with chemical maintenance in the Kanawha Valley, and in West Virginia as a whole.
"That is a fair statement," Banks said, although he added that West Virginia is not alone in having problems with chemical safety.
"We look at how things drift to a state of being, over time, and then there's a catastrophic failure, and the question is, how could that happen?" Banks said. "It evolves over time."
Moure-Eraso also said it was the chemical manufacturer's obligation to provide information on the chemicals that leaked into the Elk River and that the information that has been provided has been scant and inadequate.
The two leaked chemical compounds -- Crude MCHM and PPH, stripped -- are made by Eastman and Dow chemicals, respectively.
The federal Centers for Disease Control and Prevention have said the area's water is safe for everyone except pregnant women, with less than 1 part per million of Crude MCHM.
Moure-Eraso did not counter that standard, but he did say of Crude MCHM and PPH, stripped, "They shouldn't be in drinking water. Period. At any level."
