A new report finds pollution violations at wastewater treatment plants have been a problem in more than half of Idaho's communities.

The Idaho Conservation League's annual study of the state's sewage treatment plants says 58% violated Clean Water Act standards during 2023.

Will Tiedemann, the regulatory conservation associate with the Idaho Conservation League, said his organization didn't find much change between 2022 and 2023.

"It was kind of the status quo as continued from last year," said Tiedemann. "There were still a significant number of facilities across Idaho who violate. And of that, you know, it's usually ten, eleven, twelve facilities who make up the lion's share of that."

Tiedemann said his organization continued to study not just violations but loads over limits, or the severity of the violation.

Three facilities, in Driggs, Parma and Preston, accounted for about a third of total violations. On the positive side, 47 cities and towns did not report any violations in 2023.

Tiedemann said violations typically occur because of elevated levels of phosphorous or nitrogen from an excess of nutrients.

He noted that excess nutrients can create problems for water bodies, such as algae blooms.

"There are real world consequences," said Tiedemann, "for the environment and for recreation and for human health."

Tiedemann said violations occur more often in smaller communities - and there's a reason for that.

"Large cities in Idaho have a tax base to where they can have more advanced treatment systems," said Tiedemann. "They have more things to treat but they kind of have an outsized availability of resources to address that. But lots of smaller towns in Idaho don't always. They have limited budgets."

The Biden Administration is investing $105 million in water conservation and efficiency projects meant to shore up drought resilience, including more than $5.5 million for projects in Larimer, Montezuma, Montrose and Otero counties.

Zachary Hoylman, assistant state climatologist, said protecting water resources now and in the future will be critical for the nation's farmers and ranchers.

"Conservation is a really important piece of building resiliency," Hoylman explained. "Especially in an era of increasing variability in the climate system and longer term changes to the climate system."

The projects will optimize water deliveries to agricultural users, mitigate the risks of ditch failures by installing pipes, and install smart water meters. Shovel-ready projects in 11 states including Colorado are projected to save more than 111,000 acre-feet of water annually. One acre-foot is equal to more than 325,000 gallons of water, enough to cover a football field with one foot of water.

Hoylman pointed out there are many benefits to improving water transport efficiencies but it is also important to consider broader impacts. If you transport water by pipe instead of by ditch, it may be more efficient but it could also be taking water away from wetlands and waterfowl habitat.

"We can't only think about the human, socio-economic system," Hoylman argued. "There is really important feedback between the way that we divert water and the implications for ecology and ecosystems as a whole."

The investment taps funding allocated in the Bipartisan Infrastructure Law passed in 2021. The Bureau of Reclamation is investing a total of $8.3 billion over five years for water infrastructure projects, including rural water, water storage, conservation and conveyance, nature-based solutions, dam safety, water purification and reuse, and desalination.

Researchers in the Meadows Center for Water and the Environment at Texas State University are studying ways to determine levels of fecal contamination on Texas beaches. Exposure to fecal matter can cause nausea, diarrhea, ear infections, and rashes. A 2022 study showed 55 beaches across the state were potentially unsafe for swimming on at least one testing day a year.

Luke Metzger, executive director with Environment Texas, said researchers will develop a pilot project that will monitor bacteria levels.

"Their grant is to help use Artificial Intelligence to create a early warning system to help the public know when the beach that they want to swim in, whether it's safe to do so or not," he said.

The Meadows Center received a $500,000 grant from the National Oceanic and Atmospheric Administration. The six-month pilot program will start September first, the study will take place on recreational beaches in Harris, Matagorda and Nueces counties.

During the summer, Texas beaches are tested weekly for fecal contamination. Signs are posted on the beach if bacteria are found. The information is also posted at Texasbeachwatch.com. There are several ways beaches become contaminated.

"Rainfall can also lead to sewage overflows where our sewers get overwhelmed by the flood waters and then poop will flow out of it into our waterways. Factory farms of big feed lots of cattle can generate a huge amount of manure which in turn can get into our waterways," Metzger explained.

Houston and Corpus Christi are under federal consent decrees for having too many sewage overflows. Tyler, Houston and Corpus Christi have been ordered by the federal government to upgrade their wastewater infrastructure system.

Aurora residents and environmental groups said they will continue to oppose fracking near the Aurora Reservoir, thousands of homes and 13 schools after regulators approved a plan for more than 150 new well sites at Lowry Ranch last week.

Lauren Swain, coordinator for the group Physicians for Social Responsibility-Colorado, said while the exact scope of the risks to the reservoir remain a technical question, operators have not demonstrated how their operations will do no harm.

"You do not want to have the use of large amounts of fracking fluid and the handling of large amounts of liquid waste near a resource for 400,000 people's drinking water," Swain asserted.

The ranch sits next to a Superfund site containing decades of landfill waste, including 138 million gallons of hazardous toxins. Rep. Jason Crow, D-Colo., has asked the Environmental Protection Agency to weigh in on the risks to the reservoir and aquifers posed by fracking. Civitas Resources, which has a long track record of environmental violations, has since agreed not to drill wells directly under the landfill.

Colorado is in severe violation of national clean-air standards and critics argue new drilling will increase ground-level ozone pollution, even if operators use electric equipment. Swain pointed out the plan will also increase health risks for disproportionately impacted communities of color on the north side of the drilling area.

"There is already another Comprehensive Area Plan that's been approved in November of 2022 for about the same number of wells," Swain noted. "They'll have 300 wells near them, instead of 150."

Wildlife advocates are also concerned about the effect on priority State Wildlife Action Plan species such as the northern leopard frog, burrowing owl and swift fox. Oil and gas drilling releases benzene, methane and other toxic air pollutants. Swain pointed to studies showing living near oil and gas operations is associated with increased incidence of asthma attacks, cancer, heart and lung disease and premature death.

"Oil and gas production is responsible for a deadly series of hazardous air pollutants," Swain emphasized. "People should live nowhere near oil and gas production that releases these elements into the air."
