Native vote observers mobilize to protect SD ballot access   Study finds high arsenic levels in wells near Pinyon Plain uranium mine

Conservationists say wells within the Pinyon Plain uranium mine have unusually high arsenic levels when compared to other groundwater sources in the area.

Pinyon Plain Mine representatives argue that the toxic metal is naturally occurring, not contamination from the mining operation.

Speak up to protect Grand Canyon water from uranium mining contamination

It takes a microclimate to raise a pinyon tree - BES is the largest scientific society for ecologists in Europe. We're working towards a world in which nature and people thrive.

An active uranium mine on the ancestral lands of the Havasupai Tribe is showing elevated levels of arsenic, according to a new analysis of more than 30 years of groundwater sampling of nearby aquifers. The Pinyon Plain uranium mine, owned and operated by Energy Fuels Inc., sits inside the boundaries of Baaj Nwaavjo I’tah Kukveni — Ancestral Footprints of the Grand Canyon National Monument. The mine received permits in the mid-1980s; a drop in uranium prices shuttered it in 1992. It sat dormant for decades until 2023, when it began extracting ore. The existing permit allowed the company to avoid restrictions imposed by a 2012 rule banning uranium mining on the 1 million acres surrounding the Grand Canyon. The Havasupai Tribe, the nonprofit Grand Canyon Trust, and other conservation groups sued Pinyon in 2013 to stop mining, but a court ruled against the plaintiffs in 2022. The mine sits near the Havasupai’s sacred mountain, Red Butte, and above the deep Redwall-Muav aquifer, which feeds Havasu Creek and is the tribe’s only water source. The Grand Canyon Trust conducted the new analysis, which reviewed arsenic concentrations at 40 wells and springs in the Grand Canyon region using water quality data collected...

Global climate change is expected to produce large shifts in vegetation distribution and has already increased tree mortality, altering forest structure. However, long-term shifts will be partly depe...
