Conservation groups are concerned about a mining exploration project proposed near the headwaters of the Boise River.

The Idaho Copper Corporation is seeking approval from the U.S. Forest Service to look for copper and molybdenum, used in steel alloys, about 50 miles north of Boise. Critics of the project worry it will disturb the environment and also about the company's ultimate plan to build a large open-pit mine.

Nick Kunath, conservation program manager for the group Idaho Rivers United, said water quality is a major concern.

"Being at the headwaters of a major tributary to the Boise River, which is one of the primary drinking water sources for the city of Boise and the most densely populated area in the state, if there are any issues with water contamination or a spill, it's highly problematic and concerning," Kunath contended.

The Boise River provides about 30% of Boise's drinking water supply and helps irrigate farmland in the area, according to conservation groups. Idaho Copper said exploration will have minimal environmental impacts on the region. The Forest Service is accepting public comment on the proposal through Nov. 2.

Similar proposals in the area have been struck down by the courts twice before, in 2012 and 2016.

John Robison, public lands director for the Idaho Conservation League, said because of the Mining Law of 1872, the Forest Service cannot deny exploration projects in the area.

"If we do projects like this in the same way and putting vulnerable areas at risk, we're going to end up with the same problems or worse problems," Robison argued. "Instead, we need to protect the areas that really matter to community water supplies and figure out how to responsibly manage mining moving forward."

Kunath emphasized the Forest Service's public comment period is an opportunity for recreational users like backcountry skiers and anglers to be part of this process.

"Whatever it is, if you use this area and have questions about how this project, even at this early exploration stage, will impact the reason that you care about this area or what may change, this is the best time to have your voice heard and potentially steer the direction of this project," Kunath urged.

There are nearly 150,000 miles of rivers and streams in South Dakota, but new data show many of those don't meet state standards for safe water quality.

According to the state's 2024 surface water quality report, nearly 80% of waters studied don't meet the quality requirements for their intended uses, including recreation and aquatic life. The primary contaminants are E. Coli and Total Suspended Solids, which make rivers run brown. The report says some of the culprits are river bank erosion, runoff from large farm operations and sewage overflows.

Travis Entenman, managing director with Friends of the Big Sioux River, said those can pose human health risks through drinking water.

"When there's excess nutrients in the water, it takes more cost, energy, equipment, time, money that goes into cleaning our water before we can drink it," he explained.

Much of the contamination comes from nonpoint sources, meaning it accumulates from many small inputs, which are hard to regulate. Instead, the state offers incentives for voluntary action by landowners to prevent runoff, but Entenman said there's more interest in those incentive programs than there is funding available.

Entenman expects that to change as the Natural Resources Conservation Service, which provides technical assistance to landowners, gets funding from the Inflation Reduction Act. Projects that can improve water quality include riparian buffers, waste management systems for livestock operators and alternative practices for row-crop growers. Entenman hopes to see many people get involved.

"When a river or lake becomes impaired, it's kind of like a death by a thousand cuts," he added. "So, if you're doing the right thing, but your upstream neighbor isn't, it's not going to solve the larger issue."

The Blackwater River, which flows more than 30 miles through West Virginia's Allegheny Mountains, ranks among the top 10 most endangered rivers in the nation, according to a new report.

The river is threatened by a proposed four-lane highway construction project which would cross all of its headwater streams.

Judy Rodd, executive director of the group Friends of Blackwater, said Corridor H would involve building a bridge in an area honeycombed with old mines and explains the construction could compromise decades-old work to actively treat the water in the North Fork of the Blackwater impacted by acid mine drainage.

She is worried the highway could be a major environmental setback for the region.

"We expect in the next year to really clean up this river and bring back a trout fishery that used to be there," Rodd explained. "However, if they start building this bridge, they could be opening up old coal mines, old tunnels, which are filled with acid pollution."

Rodd noted a draft environmental impact review of the proposed project, required under federal rules, is expected to be released in the coming months.

Small businesses and the local outdoor recreation economy depend on the scenic views and wilderness surrounding the towns of Thomas and Davis. Rodd argued a four-lane highway, with accompanying construction, light and noise pollution, would drastically alter the landscape.

"It's tranquil, it's dramatic," Rodd observed. "You got bald eagles soaring overhead, you got rushing water, you got fishermen in the Blackwater Falls State Park area."

Olivia Miller, program director for the Highlands Conservancy, said the highway could be rerouted to avoid the Blackwater Falls area, and pointed to an online petition which will allow concerned residents to voice their support for a Northern route to the Federal Highway Administration.

"Right now, we are asking folks to go to the American Rivers website and fill out the action alert to send a letter to highway officials," Miller stressed.

The Blackwater River is home to the endangered Cheat Mountain salamander, eastern brook trout and many other native species.

A new, high-tech wastewater treatment incinerator, used in only a few states, is on the wish list for one Michigan city.

Former state Representative - now Mayor of Warren - Lori Stone is asking her former colleagues in the Environment, Great Lakes and Energy Subcommittee for up to $100 million to upgrade her city's wastewater treatment system.

Warren's current plant was built in 1957 and serves over 137,000 residents. The new incinerator would oxidize organic matter contained in the sludge.

Warren Wastewater Treatment Plant Director Donna Dordeski said the old system is failing.

"One of the hearths of the furnace collapsed and failed, and we couldn't use it any longer until repairs had been completed," said Dordeski. "So, from the beginning - and all the waiting, getting the contractors and repairs completed - it took four months."

Dordeski said they're approaching the final steps of getting permits for the project. And they're still seeking funds, at the state and federal levels - including infrastructure grants that may be available.

The city has around 500 miles of sanitary sewer pipes to ensure its wastewater is treated and disposed of properly. Dordeski said when the current system breaks down, it affects local residents. Trucks have to pick up and carry sludge back and forth through their neighborhoods to nearby landfills.

"That's a 24-hour operation," said Dordeski. "We usually have several trucks. Its a continuous process, five days a week, where we process the sludge and those trucks have to be nearby, available, be loaded, exchanged for a new one. So, that's what has to happen when our incinerator is not operational."

Michigan has 95 wastewater treatment plants.

Warren's mayor believes if the new incinerator is approved, the city will have the opportunity to be the proving ground as a pilot program for this technology.
