If Iowa wants to ensure its Nutrient Reduction Strategy is working to curb farm runoff, a new report from an environmental group says it needs to do a better job of monitoring water quality around the state.

The Iowa Environmental Council noted that since 2013, Iowa has committed nearly $100 million toward water-quality projects. That includes keeping an eye on the amount of nitrogen and phosphorus entering waterways from sources such as agriculture. Despite the investments, said Alicia Vasto, associate director of the council's water program, agencies involved have yet to implement an approach to see if the efforts actually are improving the water.

"We believe that if there was monitoring, if there was more information available, that it would demonstrate current efforts are not where they need to be and we need to adjust the strategy," she said.

The report recommended collaboration on a monitoring framework that would include tools such as in-stream sensors, and the results made available to the public. In a move aligned with other states along the Mississippi River, the reduction strategy seeks at least a 45% reduction in total nitrogen and phosphorus loads.

The state departments of Natural Resources and Agriculture did not provide comments for this report before deadline.

While groups such as hers push for more information, Vasto said there are signs that Iowa's water-quality situation is getting worse. This includes more algae blooms that make the water less safe for recreation.

"It just kind of lowers the average quality of life for Iowans that we can't go out and access and enjoy our public waterways," she said, "because there's this pollution that is making them toxic."

A 2018 study by the University of Iowa found a nearly 50% increase over two decades in the amount of nitrogen pollution flowing from the state to the Gulf of Mexico. Last year, state lawmakers passed a major extension of funding for its strategy, but Vasto said unless monitoring improves, that money could be going to waste.

A new study by the Oregon Department of Environmental Quality found nitrate levels have continued to rise across the Lower Umatilla Basin Groundwater Management Area.

The report found about 40% of the wells tested exceed the limit of safe nitrate levels for drinking water. Exposure to nitrates can lead to blue baby syndrome, birth defects, thyroid problems and cancer, among other things.

Kaleb Lay, director of policy and research for the advocacy group Oregon Rural Action, said the state has known about the high levels of nitrate in the area for decades but has not done enough to address the issue.

"The state's approach has been basically just voluntary measures to reduce groundwater pollution," Lay explained. "Unsurprisingly, what we've seen ever since is nitrate levels continue to go up."

Lay pointed out synthetic fertilizer, liquefied manure and wastewater are the main sources of nitrate pollution in groundwater. Factory farms, including a major dairy supplying the brand Tillamook, spread their waste on Oregon fields. Lay added the contamination disproportionately impacts low-income Hispanic communities, many of whom work on the polluting farms.

Oregon Rural Action started testing wells in 2022, Lay noted, and has found disturbing levels of contamination.

"Hundreds of people were drinking water that was polluted by nitrates and had no idea," Lay reported. "They hadn't been warned about it."

A good place to start reining in the problem, according to Lay, is to collect more data. Senate Bill 747 would require farms 200 acres or larger to report how much fertilizer they use. It would allow the state to identify overuse and advise where farmers could use less fertilizer.

In written testimony, Oregon farmers opposed to the bill said they do not overuse fertilizer and are burdened by too many regulations.

Legal action continues in efforts at cleaning up a portion of Ohio's waterways.

The Ohio EPA has been added as a defendant, along with the U.S. EPA, in a lawsuit filed by the Board of Lucas County Commissioners, the City of Toledo, and the Environmental Law and Policy Center, arguing the two agencies failed to have an effective plan to prevent dangerous amounts of phosphorus from occupying Lake Erie. Phosphorus produces cyanobacteria which appears in water as blue-green or brownish algae.

Sandy Bihn, executive director of the nonprofit Lake Erie waterkeeper, calls the EPA's control plan ineffective.

"We've got now, just in the last two years, an increase of 100,000 cattle coming into the Maumee watershed, most of it unpermitted, piles of manure on the ground here, there, and everywhere," Bihn pointed out. "You can actually physically see the manure running off into the streams."

Bihn noted commercial fertilizer phosphorus use has decreased by almost 40% but livestock is increasing and with that comes more manure runoff. She stressed the agencies being sued are more focused on the phosphorus in farmers' chemical fertilizers.

With the reduction in phosphorus, farmers are still having good yields. However, the number of livestock increases, which creates more untreated manure that seeps into nearby land and water. Excessive phosphorus pollution is joined by E. coli bacteria, pathogens, and other harmful pollutants in Ohio waterways and streams.

"About 90% of it is from runoff from the fields; agricultural runoff, and the two major sources of that are commercial fertilizer and manure," Bihn explained. "The path to reducing those harmful algal blooms is simply to reduce the sources, which is not something the programs are focusing on."

The Centers for Disease Control and Prevention said swallowing water, eating fish or blue-green algae supplements contaminated with cyanobacteria can damage a person's liver and central nervous system or cause death.

The Eastern hellbender, North America's largest salamander and Pennsylvania's state amphibian, is one step closer to receiving federal protection.

The U.S. Fish and Wildlife Service is proposing listing the species as endangered under the Endangered Species Act.

Kassie Fenn, Pennsylvania student leadership and education coordinator for the Chesapeake Bay Foundation, said their student leadership program's research and advocacy efforts led to the Eastern hellbender becoming Pennsylvania's state amphibian in 2019. She added protecting ecosystems and habitat for the hellbender will also protect habitat for other organisms.

"It's really important for the Eastern hellbender to make it on the endangered species list," Fenn emphasized. "Not only will it draw attention to the hellbender habitat, but it will also draw attention to fresh water habitats in general, and the importance of clean water and the impact it has on ecosystems."

Fenn pointed out the public has until Feb. 11 to submit comments. She noted the Chesapeake Bay Foundation recommends people sign onto its online letter, while high school students can draft their own. Comments can be submitted online.

Fenn highlighted the strong link between the Eastern hellbender and water quality, especially in relation to outdoor recreation.

"A lot of anglers in Pennsylvania love to fish for trout, either through fly-fishing or with their spinning rods," Fenn observed. "Trout really need those clean waterways and healthy waterways to survive and thrive, just like our Eastern hellbender. "

Eastern hellbenders can grow up to 29 inches and have been known to live 30 years. Fenn said evidence shows the Eastern hellbender inhabits certain streams, particularly in western Pennsylvania, although its historical range is much broader, extending into the southeastern United States.
