Las Vegas, NV - A first-of-its-kind study says predictions about hard rock mining's impact on water quality are not what they were cracked up to be. The study looked at predictions mine operators made about water quality, and then investigated in later years to see if they were accurate.

Study author Jim Kuipers says they looked at 71 mines -- and three out of four ended up with unpredicted water contamination problems.

"64 percent had mitigation failures. That's where they said, 'You won't need to worry about things because we're going to install a liner,' but the liner ended up leaking."

Kuipers says many of the problems uncovered in the study happen later, after mines are shut down. He says that should be a warning to Nevada, where many mines are still active.

"Really, time is going to tell whether Nevada fits the model of Montana, where 7 of 13 major mines in the state have resulted in long-term water treatment measures being required in perpetuity."

At Great Basin Mine Watch, Dan Randolph explains it's not the science that's broken, but that mine operators and state regulators aren't sticking with their scientific tools long enough.

"Basically, we're not getting enough samples, we're not doing the testing long enough, we're not doing enough baseline studies. Instead we're relying on mitigation measures to work, and when you look in hindsight, they do not work."

24 of the mines in the study are operating in Nevada, and Kuiper believes the most useful information for both the industry and state regulators is the part that explains why the predictions went wrong, so changes can be made to better protect groundwater in the future.

State and federal agencies are collaborating to increase the use of prescribed fires in the Northwest.

Prescribed fire is the controlled use of burns to minimize the larger risks of wildfires and smoke. It is seen as an increasingly important strategy as wildfire seasons pose greater threats to the Northwest.

Casey Sixkiller, Northwest regional administrator for the U.S. Environmental Protection Agency, said authorities want to work together to maintain forest habitats.

"Prescribed burn is one of the best tools we have for making our forests more resilient against catastrophic wildfires and they help to manage and target hazardous fuels and make for healthier forests," Sixkiller explained.

Sixkiller pointed out the EPA is involved because wildfire smoke poses risks to people's health. The collaboration is between federal agencies, departments in Oregon and Washington, and tribal governments.

Sixkiller noted the collaboration needed a formal agreement to move forward.

"That is what we've been able to do here with this agreement," Sixkiller emphasized. "To get federal land managers and states and us all in the same room, making sure that we're all on the same page about what success looks like."

Sixkiller added the collaboration has another advantage: It helps drive engagement with communities potentially in the path of prescribed burns.

"They have the confidence that the effort that's gone into planning that activity has been thought out from soup to nuts," Sixkiller acknowledged. "And that they have a seat at the table and are being engaged and their concerns are being addressed as we go forward with that activity."

A new study in the journal Nature Communications by Montana researchers said suppressing small wildfires is leading to larger, more intense and damaging blazes.

According to the U.S. Forest Service, about 98% of wildfires are fully suppressed before they grow to 100 acres; most of them within 72 hours. In Montana, the latest data show crews kept 95% of wildfires in Montana to no more than 10 acres in 2022.

Mark Kreider, a doctoral candidate in forest and conservation science at the University of Montana and co-author of the report, said the strategy leads to what is known as fire "suppression bias."

"Removing more of one type of fire than the other, what we're left with is bias towards the higher intensity fires, these more extreme fires," Kreider explained.

Montana state policy calls for crews to extinguish fires as quickly as possible, even small ones. Kreider pointed out researchers recommend letting low-intensity fires burn where possible to reduce the risk and damage potential for larger, hotter-burning and more catastrophic blazes.

Kreider acknowledged as the population grows along the urban-wildland interface, letting fires burn is not always possible, but argued it might be the best strategy for heading off catastrophic fires later.

"Especially in the western U.S. where people live close to forests, fire suppression is very important and we still must do it," Kreider noted. "But this research helps to show when possible in places where it's safe to do so, we really may benefit from allowing more low and moderate intensity fire to burn."

The National Interagency Fire Center said the number of acres scorched by wildfire has doubled since the 1980s, and the cost to battle the fires has risen to nearly $3 billion a year.

The Montana Department of Natural Resources and Conservation has awarded $3.1 million for 13 projects to reduce wildfire risk to communities and improve forest health.

The funding money is part of the $15 million Montana Forest Action Plan, which takes a big-picture approach to reducing the risk of wildfires.

Wyatt Frampton, deputy division administrator of forestry and trust lands for the Montana Department of Natural Resources, said the money will be used to foster fire-management cooperation between state and private landowners across 3,200 acres of forest.

"Through a variety of activities, such as prescribed fire, logging, mechanical thinning, hand activities as well as tree planting," Frampton outlined.

The 13 most recent restoration projects are spread across the state, including in Lewis and Clark County, the Bitterroot and the South Swan Valley.

Frampton said the DNR is aiming to create a cohesive fire-reduction plan across Montana's landscape, which has until now been inconsistent because of different sets of land-management practices.

"Right now when we see a patchwork of treatments across some of the landscapes in the state, from a fire-management perspective, it doesn't create a clean or effective barrier for trying to stop the fire in that area," Frampton explained. "Where, if we had a cohesive landscape-level treatment, that would help."

Frampton added having a statewide cohesive fire-management plan would also allow the DNR and other agencies to slow the spread of potentially destructive insects in Montana's forests.
