COLUMBUS, Ohio – With the waters of Lake Erie starting to warm, concerns are rising about the possibility of toxic algal blooms over the summer months.

There are evidence-based agricultural practices that can reduce the threat, so why are they not widely used?

New research of solutions and behaviors found that goals to reduce nutrient runoff linked to algal blooms are feasible, as many farmers are motivated to use best practices.

However, Robyn Wilson, associate professor of risk analysis and decision science at Ohio State University’s School of Environment and Natural Resources, explains real and perceived barriers are preventing action.

"We see a lot of people being willing to use cover crops,” she says. “But when you dig into why they're not doing it, what we see as a reason at an individual level, farmers lack confidence in their ability to successfully implement them. And they also question how effective cover crops are as a solution."

Wilson, who led the research, says farmers need better cost-benefit information, support tools and technical assistance to execute recommended practices.

According to the study, the most effective strategies to reduce nutrients are the use of phosphorus application guidelines, subsurface fertilizer application, erosion controls and water-management practices.

Voluntary and mandatory approaches to address algal blooms are suggested. And Wilson explains well-designed outreach and incentive programs could increase voluntary adoption, such as the installation of water filtration measures on fields currently in use.

"That's going to require economic incentive because no farmer's going to volunteer to take land out of production,” she states. “We have some pretty conservation-minded farmers, but that's still a pretty big ask for them. We're asking them to do something for a collective benefit at an individual cost."

Wilson also recommends further understanding of the motivations behind the use of certain practices, and how to best ensure long-term use. That's because improvements won't happen overnight.

"Even if another 40 percent of farmers started using these practices tomorrow, would we see those benefits from the lake in the next year or two?” she questions. “Maybe not. So some of those processes take a while to play out to get the positive changes from an environmental standpoint."

Wilson says she's encouraged by the research, as well as Gov. Mike DeWine's recently proposed $900 million fund to improve water quality, specifically focused on Lake Erie.

Iowa lawmakers are considering a bill that would require property owners to disclose the presence of lead water service lines during a real estate transaction.

Some of Iowa's residential water lines date back more than a century.

The Centers for Disease Control and Prevention estimates at least half of the children in the United States are at risk of lead exposure from water lines.

The Iowa Environmental Council's Director of Climate Initiatives Cody Smith said the problem is especially acute in Iowa, where most of the homes built before 1980 have lead in the lines that bring water to the house, and added it will be extremely expensive to address.

"It's estimated that fixing Iowa's lead service line issue would cost about $900 million statewide," said Smith. "So, this is a pressing health concern for the children in our state."

Iowa is responding to a federal rule passed last year that requires all service lines that contain lead to be replaced by 2035.

House File 876 would require sellers to disclose that their house has lead service lines in a real estate transaction.

Iowa utility companies are notifying people if their house has lead in its service lines and offering assistance to remediate it.

Smith said homeowners can also find out for themselves if there's lead in their pipes.

"You can use, like, a penny to scratch your service line where it comes in to often the foundation of your home," said Smith. "And you'll see if it's copper. It it's copper, you're fine. Or if it's PVC plastic, you're fine. But oftentimes, it's going to be a lead service line."

HF 876 has passed the Iowa House and awaits action in the Senate.

Both water quantity and quality are important in the dry climate of Nevada. Now, a proposal from the Environmental Protection Agency could roll back protections for the state's water resources.

EPA administrator Lee Zeldin said he wants to reduce protections granted under the Clean Water Act in an effort to undo "unfair burdens" on farmers and landowners. The 1972 federal law aims to maintain and restore the nation's waters.

Natasha Majewski, climate and energy consultant for the Nevada Wildlife Federation, said the waters covered by the act have changed over the years, but it is all an interconnected system.

"Lincoln County doesn't have the same amount of resources as Clark County, and yet water is still flowing from that county into tributaries such as the Muddy River," Majewski pointed out. "That goes into the Colorado River. That will end up being drinking water."

In 2023, the Supreme Court narrowed the definition of "waters of the United States." It determined only wetlands physically connected to other federally-recognized waters qualify for protection.

Majewski noted while Nevada has its own water laws, federal regulation is needed to maintain a baseline for all states. This week, listening sessions about the proposal will be held for government agencies and Native American tribes.

The Trump administration has said it wants to reduce "red tape" for business and industry but conservationists fear loosening restrictions will cause more pollution in Nevada's wetlands and ephemeral streams. Majewski argued water should not be a partisan issue.

"It is important that all Nevadans, whatever kind of political side they are on, are able to understand these issues more," Majewski stressed. "Because water, it surpasses the administration that it's currently in."

Majewski added changing water protections could affect the quality of the Colorado River and would cause complications due to the amount of agencies managing the river.

"The Colorado River and its different tributaries that come in, it is such a patchwork of people that manage those water sources," Majewski explained.

Montana officials have denied a petition asking the state to designate the Big Hole River as "impaired" by pollution.

Two conservation groups collected data over five years and found levels of nutrients in the Big Hole River exceeded thresholds, in some parts, by twofold or threefold, which could harm aquatic habitats, contaminate drinking water and affect fishing and other tourism business. The Montana Department of Environmental Quality said the petitioners used the wrong metrics.

Guy Alsentzer, executive director of the conservation group Upper Missouri Waterkeeper, said it is an example of politics "undermining good science."

"At minimum, we feel that the state owes us a written explanation, with some detail, about exactly why it believes it can deny a petition that has clearly satisfied the scientific basis for developing a pollution cleanup plan," Alsentzer explained.

The Montana Department of Environmental Quality argued the petition's data does not abide by a state law passed in 2021. The federal Environmental Protection Agency, however, officially disapproved of the law.

Alsentzer has requested the EPA weigh in, adding once high nutrient levels are proven, it is up to the Department of Environmental Quality to determine the causes.

"In the case of most Montana rivers, it's going to be a combination of human land use patterns," Alsentzer noted. "Sometimes it's subdivisions, sometimes it's septics, sometimes it's a municipality and sometimes it's farm fields or big cattle feeding lots."

Alsentzer stressed keeping waterways healthy is both "good common sense" and "good economics." According to the Bureau of Business and Economic Research, Beaverhead County's hunting and angling economy adds an estimated $74 million to area households annually and $167 million to businesses and organizations.
