Asarco finally admitted to having buried 55 gallon drums of hazardous waste....

"But as to the company’s recent reversal of position – in which Asarco now admits to having buried some barrels – Arrigo said he is “quite surprised.” He said he’s now looking forward to seeing what CRG’s lawsuit and ground work uncovers.

“I’ll be real interested to find out what’s down there,” Arrigo said."

" Specifically, Meyer said Asarco’s tailings impoundment, which captures waste from the mining operation, was leaking into nearby Lake Creek.

He also said the company bypassed part of its wastewater treatment plant, sending sewage and other waste directly into the tailings impoundment. And, perhaps most surprising, Meyer claimed Asarco was burying 55-gallon drums of hazardous waste in what he termed “midnight burials.”

All of those claims have been disputed by the company, and the matter has recently found its way into federal court. But long before the first motions were filed, some eight years ago, to be exact, Jim Meyer blew his whistle in the Troy woods, expecting state regulators to hear his alarm."
