The U.S. Environmental Protection Agency has released the results of dozens of water tests following the Gold King Mine spill last month. The tests were conducted at sites on Animas and San Juan rivers, other tributaries, on Lake Powell, and near the City of Page as recently as Aug. 25.

Earlier this week, Navajo farmers in New Mexico voted to keep irrigation canals along the San Juan River closed for at least a year. They have concerns about soil contamination following the Gold King Mine spill in Colorado. Meanwhile, officials in Page are worried about the incident causing a drain on the local economy, even though scientists say Lake Powell remains mostly unaffected.  Arizona Public Radio’s Ryan Heinsius reports.

A petition submitted today by a nonprofit environmental group seeks to trigger federal reform of uranium mining regulations on public lands.

The petition focuses on so-called “zombie” mines that have been reopened after long periods of inactivity. It asks for limits on how long a mine can remain on standby, as well as new environmental reviews when an old mine reopens. It also proposes regular inspections of inactive mines, long-term water monitoring and firm deadlines for reclamation.

Arizona environmental officials say they don’t expect the Gold King Mine spill to have any negative impacts to the state’s watershed. As Arizona Public Radio’s Ryan Heinsius reports, they say Lake Powell will likely disperse the waste made up of several heavy metals.

The toxic plume from the Gold King Mine spill in Colorado last week is no longer visible as it’s mixed with the murky San Juan River. Officials say it’s uncertain whether the polluted water has reached Lake Powell. Arizona Public Radio’s Ryan Heinsius reports.

A massive wastewater spill from a Colorado mine is expected to reach Lake Powell sometime this week.

About three million gallons of wastewater poured into the Animas River last Wednesday after a breach at a defunct gold mine near Silverton. The contaminated water has reached the San Juan River in New Mexico, which flows into Lake Powell on the Colorado River.
