KETCHUM, Idaho – Water quality in and around the Snake River in southern Idaho is on the decline, according to a new report.

The Idaho Conservation League's survey of the Eastern Snake Plain Aquifer finds an increase in pollutants, especially nitrogen and phosphorus – in some cases exceeding state and federal water-quality standards.

Josh Johnson, central Idaho conservation associate with the Idaho Conservation League, explained the Magic Valley's 417,000 cows produce waste equivalent to a city of 12 million people, and that waste isn't being treated before seeping into the aquifer or running into bodies of water.

"Which, of course, we would never let that happen if it was a human city," said Johnson. "But in this case, all that cow manure is being put on the fields, on the land, and adding a lot of this nitrogen and phosphorus to the groundwater."

The aquifer supplies drinking water to more than 300,000 Idahoans. The report says the industrialized dairy industry, which is growing rapidly in the region, is a leading source of contaminants.

Johnson said the State of Idaho needs to better monitor and regulate the amount of pollution going into the water system. He added the state will also have to tackle waste from the dairy industry, which affects water quality as well as the rest of the environment.

"We need to figure out how can we best deal with this waste and how can we reduce the impact that it's having," he said, "both from a water pollution perspective, such as what we detail in this report, but also from a climate change perspective, just from some of the methane and other gases that come out of there."

Idaho is among the top five largest dairy-producing states in the country. Johnson noted that this report shouldn't cause alarm for the public, but it indicates a growing problem that needs to be addressed.

"Don't go into the water" is a warning Illinoisans may want to heed. A 2024 study released this week found all state-border beaches on Lake Michigan last year had evidence of contamination.

Findings from the Safe in Swimming report indicate these conditions could cause serious gastrointestinal and respiratory ailments. The data show bacteria levels were well above the EPA's "Beach Action Value" water quality standards. These guidelines help determine advisories and closures.

Emily Kowalski, outreach and engagement manager for the Environment Illinois Research and Education Center, explained the odds of exposure.

"One hundred percent of those beaches had potentially unsafe levels of fecal indicator bacteria at least one day in 2024, meaning that swimmers were potentially at risk," she said.

A water sample exceeding acceptable BAV standards increases the chances of a higher illness rate among swimmers. The study shows 71% of Great Lakes beaches had at least one potentially unsafe test day. Three beaches in Cook County had the highest degrees of dirty water - Winnetka Lloyd Park had the highest at 21. Glencoe Park and Montrose beaches had 14 days each.

The study identified runoff from paved streets and parking lots, and overflow from outdated, bacteria-encrusted sewage systems as harmful contributors. Livestock waste from concentrated animal feeding operations, or CAFOs, is another source.

Human contact with water tainted by manure could cause an E. coli infection. Kowalski suggested the environment could be one solution to interrupt the pathogen flow.

"Investing in nature-based solutions, green infrastructure, but also the repair needed in aging sewage systems nationally," she continued.

An estimated 57 million Americans experience nausea, diarrhea, ear and eye infections, and skin rashes after swimming in polluted waters. Kowalski adds the EPA estimates a price tag of $630 billion over 20 years will be needed to address sewage runoff and other wastewater problems nationwide.

Following last year's historic drought in Montana and hot temperatures early this spring, the Blackfoot River is running at roughly 25% of normal water levels.

Water rights have shifted some this year but experts said management will continue to be community-driven.

Clancy Jandreau, Blackfoot water steward for the nonprofit group Blackfoot Challenge, said the river's fish population declined in the late 1980s and early 90s, but there has also been a long history of restoration efforts. The new Blackfoot Drought Response Plan, updated in April, helps build on those efforts, Jandreau noted.

"We really wanted to more explicitly recognize that habitat restoration efforts that improve fisheries can in and of itself be a response to drought, as it builds resilient fisheries," Jandreau explained.

The new plan also incorporates deferred changes from the 2015 Montana Water Rights Compact, in which the Confederated Salish and Kootenai Tribes and Montana Fish, Wildlife and Parks became co-owners of a water right historically associated with hydropower production.

During a dry summer like this one, Jandreau pointed out the drought plan encourages a "shared sacrifice for shared benefit" model, in which irrigators, anglers and other water users voluntarily reduce their effects on the resource.

"Everybody's going to be seeking the refuge of the river over this summer," Jandreau added. "That includes humans and wildlife. So just doing their best to be aware of that and being responsible and ethical recreators this summer out there on the river."

Because of drought and failing infrastructure, the state of Texas will run out of water by 2030, according to the Texas Water Development Board.

But two new pieces of legislation are on the books that are designed to address the state's water shortage.

Senate Bill 7 and House Joint Resolution 7 would allocate $20 billion for infrastructure improvements and new projects.

Agriculture Commissioner Sid Miller said he's been trying to get lawmakers to address the state's water crisis for 10 years.

"We completely lost our sugar cane industry because - no water," said Miller. "We've brought it to light that Mexico is not paying their water bill with our treaty on the Rio Grande, so that was brought to light. We've got a drought over half the state of Texas."

An increase in population has also contributed to the state's water woes.

JR 7 would authorize the state to use $1 billion a year from sales tax revenue for the water projects. The resolution must be approved by voters in November.

If the amendment is approved, the projects and funds will be overseen by the Texas Water Development Board. Miller said in the meantime, the state needs to do a better job at managing the water it has.

"We spend millions and millions of dollars on stormwater drainage, getting rid of excess water when it rains," said Miller. "We need to capture that water and use it. We need to capture the water out of these water treatment plants. I'm not advocating that we drink it but, my farmers sure would like to irrigate with it."

Miller said the state can also benefit from rainwater harvesting. He added that up to 70% of the state's water is lost, as it's transported to various municipalities because of old, worn-out infrastructure.
