EPA Says Rivers It Polluted Are Clean — Because All The Toxic Metals Have Flown Into Lake Powell
Good news: high concentrations of toxic metals from a mine blowout caused by the Environmental Protection Agency (EPA) are no longer detectable in the Animas and San Juan rivers, according to an agency report.
The bad news is, fall storms and spring snow-melt likely drove 1,115,539 pounds of toxic metals from those rivers to Lake Powell — a vacation spot for millions of people and water source for drinking and agriculture.

The report is a scientific analysis that focuses on understanding the river conditions before the GKM release; the movement of the GKM release through the river system; and what has happened to water quality in the river since the time of the GKM release.
The research supports EPA’s earlier statements that water quality in the affected river system returned to the levels that existed prior to the GKM release and contamination of metals from the release have been moved through the river system to Lake Powell.
The GKM release included aluminum, iron, manganese, lead, copper, arsenic, zinc, cadmium, and a small amount of mercury.
