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.

The Environmental Protection Agency said the country's aging systems of water pipes are hotbeds for chemical and lead contamination.

More lead service line replacement programs exist in Illinois than any other state and Chicago alone has well over 400,000 lead pipes.

The nonprofit group Elevate wants everyone to have clean, safe drinking water, regardless of income or geographic location.

Patrick MacRoy, vice president of environmental health and water programs for the group, said one demographic has a higher susceptibility to lead poisoning.

"We've been focusing on child care facilities," MacRoy pointed out. "With the State of Illinois, we help administer a program to provide child care facilities with free lead and water testing, to help them meet their licensing requirements."

Extra attention, he added, is given to home-based child care sites because they are more likely to have a lead service line. Last month, President Joe Biden's Bipartisan Infrastructure Law allocated $15 billion to replace the country's weakening pipes.

Part of Biden's infrastructure law is adherence to the "lead and copper rule," removing the elements from water pipes by 2034. To better understand the mandate, the Environmental Defense Fund released a new national map of lead service line replacement programs to help locate and replace lead pipes that deliver water to homes.

Elevate's LeadCare program is focused on lead removal, which MacRoy explains is complicated and expensive.

"You have to open up a hole at the water main to make the connection, run a pipe across the yard and then reconnect it in the home, restore the property to its original condition, whether that's putting in grass seed or sod, or fixing landscaping or fixing interior drywall that you had to open up to get to where the pipe comes in the house," MacRoy outlined.

MacRoy added he welcomes federal resources and hopes to work with state and local governments to make sure they are distributed equitably to help neighborhoods that need them the most.

A 2024 study from Johns Hopkins University found 68% of Chicago children of color younger than age six are exposed to lead-contaminated drinking water.

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.
