Anglers won’t be able to catch as many lake trout around the Apostle Islands on Lake Superior after the Wisconsin Natural Resources Board approved a 15 percent cut as the lake trout population has declined.
The owners of a proposed $1 billion gas-fired power plant in northern Wisconsin are officially calling it quits on the Nemadji Trail Energy Center in Superior.
The policy-setting board for the Wisconsin Department of Natural Resources is set to vote Wednesday on whether the agency can begin crafting groundwater standards for roughly two dozen pesticides.
Since launching their campaigns for Wisconsin governor, both Republican U.S. Rep. Tom Tiffany and Democratic Milwaukee County Executive David Crowley have touted the concept of local control.
Each argues that communities deserve “a seat at the table” in matters of commercial and industrial land use, but their records as public servants illustrate contrasts about when competing local and state interests should carry the day.
“I want to get Madison out of the way where it makes sense,” Tiffany told attendees of the annual Wisconsin Counties Association conference in September. “Local officials understand their communities, and state government should be working with them rather than creating additional obstacles.”
Yet Tiffany is an architect of some of the most consequential environmental regulatory rewriting of the past 15 years, stripping municipalities of several powers to regulate shoreland development and mining in their own backyards.
Crowley has worked with the state to address Milwaukee County’s budget issues. Just a few years ago, Milwaukee County was heading for a “fiscal cliff,” the culmination of a decades-long pension scandal.
Without state intervention and the “tools to raise additional revenue and fund local priorities,” the county would face “tough decisions,” Crowley wrote in 2022. The following year, the Legislature authorized Milwaukee County to increase its local sales tax rate by almost half a percentage point.
Neither candidate has offered many specifics in their campaign pitches, and neither campaign responded to requests for comment.
But their policymaking records offer some clues.
During Tiffany’s time in the Wisconsin Legislature and Congress, he has conveyed a general desire to get the state and federal government “out of the way” of local decision-making. Crowley’s time as a county executive and state Assembly member highlights his support for public spending on property development and the creation of minimum environmental standards to protect public health.
Local control and mining operations
Crowley has argued for “a case-by-case” treatment of mining projects without staking a claim over the industry’s merits.
Still, he continues to push for amassing consensus and would not rule out allowing new mining permits before consulting with local communities.
In January, when a PBS reporter asked him to explain how he would respond to new mining permit requests, Crowley said he would convene a work group of experts to obtain the best information possible.
“It’s about working with the local municipalities, working with the groups and the stakeholders that are on the ground,” he said.
Comparatively, Tiffany’s time in the Wisconsin Senate from 2013 through 2020 saw him take up the mantle of getting the miner, emblazoned on the Great Seal of the State of Wisconsin, back to work. He ushered in several bills intended to loosen restrictions that businesses said stymied economic growth.
The first of several successful proposals started with the 2013 reworking of the state’s iron mining law, which instructed regulators to start the mining permitting process on the presumption that some environmental damage to wetlands is a necessary operating condition of the industry.
Supporters maintained the reforms assured developers they could expect regulatory certainty and expeditious review of new projects.
A few years later, prompted by a bill Tiffany co-authored, the Legislature lifted the state’s moratorium on sulfide mining, which can release toxins, and stopped requiring companies to prove they could successfully operate and close sulfide mines elsewhere in the United States or Canada without polluting the environment.
Tiffany also sought to curb local authority too when regulations posed risks to obstructing economic development.
Two 2013 bills proposed restricting local governments’ ability to regulate nonmetallic mining, including frac sand operations, and would have prohibited them from creating water quality and air quality standards, permits, restrictions and monitoring requirements.
Tiffany told Wisconsin Watch at the time that some local units of government are “trying to establish mini-DNRs,” by conducting their own air and water testing. “That’s the purview of the state,” he said.
The contentious proposal didn’t make it to the chamber floor for a vote.
Local control and land acquisition
In 2015, Tiffany co-sponsored legislation that took the opposite view on local control in the context of land acquisition.
Republicans and Democrats have long clashed on how to finance the Knowles-Nelson Stewardship program. The fund enables the Wisconsin Department of Natural Resources to purchase private land and easements for habitat preservation and recreation or issue grants to organizations or municipalities to do the same.
Both Tiffany and Crowley say they support allocating money for the program, but Tiffany has long expressed reservations about its focus on purchasing new property.
In 2015, Tiffany sought to curb state authority by requiring the Wisconsin DNR to obtain approval from every municipality and the county in which the property is located before acquiring new properties. The bill didn’t advance to a vote. Tiffany now says he would fund the program so long as the dollars maintain existing public lands.
Crowley has said repeatedly he supports strengthening the program, drawing parallels to his support for county lands.
In the last five Milwaukee County budget cycles, he recommended county leaders spend tens of millions of dollars on parks and trails, drainage infrastructure and waterfront protection.
In other environmental areas, Crowley also has reined in local control by creating baseline standards. As a state legislator, he backed bills that would have imposed statewide requirements for mandatory lead testing and inspections and restricted the ability of municipalities to privatize their public water or sewer utilities.

SPRINGDALE, Pa. — Residents in a small southwestern Pennsylvania town are facing the prospect of a 47-acre data center facility on their doorstep.
“Right here behind this fence is where they want to put up the data center, and as you can see, there’s houses right across the street, roughly 100 feet,” said lifelong Springdale borough resident Cathy Mager, stretching her arms to show the distance from the development site’s perimeter to a line of houses across Porter Street.
“We don’t want it,” she told States Newsroom on Oct. 19

The scenario is playing out around the United States. Both Democratic and Republican candidates during the heated midterm election cycle have had to navigate deep voter resentment of the massive advanced computer server farm developments that will power artificial intelligence.
“The issue has blown up over the last year,” said Darrell West, a senior fellow at the Brookings Institution’s Center for Technology. “It wasn’t that long ago politicians were fighting to bring data centers to their communities. Now these facilities are completely controversial, and many people don’t want them in their neighborhood. So public opinion has changed very rapidly on this issue.”
53 years with a power plant
Mager is among a few dozen residents in Springdale, in northeastern Allegheny County, who formed the group Save Allegheny Valley Environment to protest the proposed data center development on the community’s riverfront site of a coal-fired power plant that went offline in 2022.
“We’ve already lived for 53 years under that power plant,” said Vicki Wanamaker, 66, a lifelong Springdale resident who lives about a 10th of a mile from the fencing around the site.
She’s worried now about the noise a data center would bring to the neighborhood, with its water coolers running and back-up diesel generators on site, and whether she would experience electricity shortages.

Springdale’s council voted 5-2 in December to approve a conditional use permit for the project by Dynamo DC, a company with a Springdale-based address that “builds AI data centers on environmentally remediated brownfield sites,” according to its website. Residents are now asking Allegheny County to stop further land use plans.
Dynamo DC spokesperson Brian Regli said the developers will use “acoustical shielding” to keep noise well below ordinance levels.
The hyperscale data center will recycle 500,000 gallons of water in a closed-loop system to cool the servers, he told States Newsroom during an interview in late October. The facility is planned to handle up to 240 megawatts, which it will pull from a regional electricity grid, Regli said.
Dynamo DC has not yet identified which company or contractors will actually use the data center. The company plans for the data center to go online by 2029.
Regli said the company is exploring “environmentally conscious” fuels for the diesel back-up generators. The amount of back-up power needed for the site will ultimately depend on how the data center is used.
Some uses “may need a fraction of the backup power that we put forward,” he said. “But you know, if this is a critical facility, let’s say it is being used by the military — which I doubt that the center would become that, but let’s use that as an example — you’re going to want to have as robust of a backup infrastructure as you can,” Regli said.
Amie Downs, of Caveat Communications, which is providing communications for Springdale, said the borough “was able to negotiate a number of other provisions that benefit the community and its taxpayers that relate to noise, lighting, traffic, landscaping, and other requirements, imposing stricter standards than the borough’s ordinances otherwise required.”
Thousands of data centers planned
Data centers are a linchpin of the modern internet, but the scale needed for advanced computing is new.
There are 1,394 data centers already operating around the United States, and they carry a combined capacity of 64,764 megawatts.
As of October, 2,841 more data centers are planned and would add 413,152 megawatts of additional capacity, according to the energy market firm Cleanview’s data center project tracker.

“What we’re seeing now is huge facilities that are being built. These are data centers that occupy the size of several football fields,” said West, who also publishes the progressive organization’s TechTank and is a senior fellow on governance studies. “They require a lot of energy. Some of them require water as well. So the size of the data centers creates public anxiety and worry.”
Sixty-three percent of American adults say they don’t want a data center built in their community, according to a late August poll published by YouGov and The Economist.
A CNN poll conducted in mid-September found nearly two-thirds of registered voters surveyed said AI and data center development will be an extremely or very important factor in their vote this midterm election. The poll also found a partisan divide: Democrats are 26 percentage points more likely than Republicans to say they’re very concerned about data centers, according to the results.
From Trump on down
The issue is permeating politics and races at the federal, state and local levels.
President Donald Trump on Wednesday wrote on his Truth Social platform that data centers “are mandated by me to make their own electricity.”
“If companies want to make their Data Centers popular, pay the community, and/or individuals within the community, a ‘dividend.’ … MAKE DEALS, and get them built!!!” he wrote.
The statement is a pivot from his late August post, when he called opponents of data center developments “backwards and poor.”
Everyone is talking about data centers ahead of the midterm elections. I heard from residents in a Pennsylvania neighborhood where a hyperscale data center is proposed for just outside their doorsteps. Read more: www.newsfromthestates.com/article/we-d…
Resentment against the large-scale projects has become a dominant issue in hotly contested U.S. Senate races that will determine party control for the closely divided upper chamber.
A Democratic-backed political action committee poured $2.5 million in late October into ad campaigns depicting incumbent Republican U.S. Sens. Roger Marshall of Kansas and John Husted of Ohio as friends of the tech industry and AI developers.
States Newsroom did not immediately receive a response for comment about the new ads from Husted’s and Marshall’s reelection campaigns.
Marshall told the publication Semafor in July that he was supportive of data center moratoriums. Husted blamed Senate Democrats for blocking a procedural vote in late September on a House-passed bill that aimed to regulate electricity costs associated with large-scale data center projects.
Not all Democrats voted against the measure. Democratic senators who voted for it included Jon Ossoff and Raphael Warnock of Georgia, where Osoff is seeking reelection; Minnesota’s Amy Klobuchar, who is running for governor; and New Hampshire’s Maggie Hassan, who is not seeking another term.
West said anxiety about data centers exists on both sides of the aisle, but that it’s become a “partisan issue in the election because Republicans historically have been more pro-business.”
“Democrats are now using that past support for tax breaks against Republican officials,” he said, pointing to Texas Gov. Greg Abbott’s pause on data center development after rapid growth. Abbott is seeking reelection this November.
But party lines on the issue blur, West noted.
Pennsylvania politics
Pennsylvania Gov. Josh Shapiro, a Democrat who is seeking reelection, has touted the commonwealth’s infrastructure and workforce as ripe for hyperscale data center and AI development, and until recently provided a fast-track permitting path.
In June 2025, he joined state leaders from both sides of the aisle to announce a $20 billion investment by Amazon Web Services for two development sites, including a 1,200-acre site in northeast Pennsylvania that would reportedly consume as much energy as 900,000 homes and require millions of gallons of cooling water each day.

The technologies, he said, “should be developed by the hands of a Pennsylvania worker…not in communist China,” according to the Pennsylvania Capital-Star.
Under pressure from grassroots opposition and from his Republican challenger, state Treasurer Stacy Garrity, Shapiro signed an executive order in August 2026 mandating energy usage and transparency requirements on “greedy” data center developers.
In Pennsylvania state politics, Hadley Haas, a Democrat vying to unseat Republican state Rep. Valerie Gaydos in the 44th House District, said data center regulations have become a main issue in her campaign.

“There’s just a generalized anxiety, I would say, about AI and data centers, especially around the cost of utilities,” Haas told States Newsroom. “Sometimes people will bring up water consumption or noise and that kind of thing. But mostly, they’re concerned about the cost implications.”
Haas said her platform includes “guardrails” on data center development. She accused her opponent of flip-flopping on the issue — voting “no” in March on a data center regulation bill in the Democratic-led Statehouse, but then announcing support for a 180-day pause proposal in July.
“People started to see actual data that this was an issue that was a concern for people, and that’s when we saw more of the Republicans starting to chime in,” she said.
States Newsroom reached out to Gaydos’ campaign for comment but did not receive a reply.

Pennsylvania’s 44th House District occupies the west side of Allegheny County, where the 15-member countywide council voted unanimously in September to ban the development of data centers over 25 megawatts on any county-owned land, including vast tracts of park land.
Council member Kathleen Madonna-Emmerling, who represents a portion of the county’s western side, said, “It’s important we do this proactively because it gives us the strong legal foundation to deny those permits without discriminating against a certain type of business.”
States Newsroom reached out to all members of the Springdale borough council for comment but did not hear back.
West said he expects “this issue is going to stay on the political scene for several years as people debate how we should handle these facilities.”
At the end of 2025, Milwaukee Water Works still had over 55,000 residential homes or properties with lead water lines on the utility-owned side, customer-owned side or both. The utility had yet to identify the makeup of pipelines serving another 27,000 properties.
But Milwaukee can’t replace all the pipelines at once — and some neighborhoods face greater risks from lead exposure than others.
So which areas should officials prioritize?
Part of the answer lies in a surprising place: a tool University of Wisconsin-Madison researchers originally developed to study the connection between neighborhood disadvantage and human health.
Lead does not impact neighborhoods equally
Milwaukee’s pipeline problem dates back to 1872, when the city mandated the use of lead in service lines. Although the city abolished the mandate in 1962, older lead pipelines remained in many older residential buildings.

Today, most homes known to have lead lines are concentrated in the older neighborhoods surrounding downtown, while most homes with service lines made of “unknown” materials tend to be farther away.
Downtown Milwaukee includes a scattering of homes with non-lead service lines — many due to having already been replaced by the city.
Milwaukee has replaced nearly 15,000 pipelines since beginning its broader efforts in 2017, said Milwaukee Water Works Superintendent Patrick Pauly. When federal funding became available under the Bipartisan Infrastructure Law, the utility expanded its effort, increasing the pace from about 1,000 lines a year to 5,000.
But scaling up the effort required more than funds and construction crews. The city also needed a systematic way to decide where to work — one that recognizes disproportionate risks across the city.
“We needed to expand the lead service line replacement program, and we needed to develop a, for lack of a better word, defensible method to expand that program,” Pauly said.
70% comes from the Area Deprivation Index (ADI), a measure of relative socioeconomic disadvantage developed by UW-Madison researchers.
25% comes from the percentage of local children who tested positive for lead poisoning.
5% comes from lead service line density in the area.
Together, these measures help the utility determine where replacement will yield the highest benefits.
The city updates each property’s score every other year as new information becomes available, Pauly said.
The scoring weights heavily toward neighborhood disadvantage as broader challenges residents face can compound risks posed by lead exposure.
Nationwide, communities burdened by economic disadvantages and racial inequalities can face greater risks of lead exposure, according to a Montclair State University study of New Jersey. Such neighborhoods often contain older housing and sit near former industrial sites.
The ADI relies on attempts to quantify disadvantages in Milwaukee, and its origins have little to do with water infrastructure.
A tool developed to understand health disparities
The ADI measures neighborhood socioeconomic disadvantage or adverse social exposure using 17 U.S. Census American Community Survey measures. They include factors related to income, education, housing, and employment.
The index assigns scores to census block groups — small geographic areas that generally contain several hundred to a few thousand people.
Block groups receive a national percentile ranking from 1 to 100 or a statewide decile ranking from 1 to 10. Higher rankings indicate greater socioeconomic disadvantage relative to other areas.

Researchers have long recognized that people’s health depends on far more than the medical care they receive. But measuring the influence of social and economic conditions on health isn’t easy.
Dr. Amy Kind has spent much of her career trying to figure that out.
Kind, a professor of geriatrics and gerontology at UW-Madison and founding director of its Center for Health Disparities Research, grew up in Niagara, Wisconsin, before training as a physician.
During her residency in Boston, she saw that the medicine she prescribed could do only so much when patients returned to homes without healthy food, stable housing or access to other basic resources. Those experiences helped shape her interest in finding ways to measure such disadvantages.
Researchers have used indexes like ADI since the 1980s. In 2014, Kind led a group of University of Wisconsin School of Medicine and Public Health researchers in updating ADI using modern census data, refined it to the census block level and validated its usefulness across several scientific studies.
“(Like any marker), it may not be the thing that ultimately drives the risk,” Kind said. “But it has been an extremely strong marker that something going on in that area is increasing risk, whatever it might be.”
An unexpected use for health research
“When we first developed the metric, we thought that perhaps it would be used primarily by health systems, primarily in the research community,” Kind said.
Instead, Kind and her colleagues heard from many community groups and local governments that were interested in using index data to guide their public health work.

Since 2014, the University of Wisconsin has tracked over 3,500 academic papers citing the index and more than 400 examples of its use across different fields. That includes a recent Kind study linking environmental factors to the likelihood of developing Alzheimer’s disease. Meanwhile, the index helped officials in Puerto Rico decide where to send nurses to combat dengue fever and the mosquitoes that carry it.
That wide interest prompted Kind to develop the Neighborhood Atlas in 2018, making the data more accessible.
Kind said she enjoys seeing the index be used in sometimes unexpected ways to address local challenges. That includes Milwaukee’s effort to protect children from lead exposure, where officials are using it as one component of their model.
Thousands of pipelines replaced, thousands more to go
Milwaukee Water Works has replaced lead pipes at more than 6,000 properties under its priority program, which launched less than three years ago.

The work has been largely concentrated on the city’s North Side but has also expanded into near South Side neighborhoods.
Pauly expects the utility to reach a milestone next year of 20,000 lead lines replaced.
But officials will soon face a difficult question: how to pay for replacements after Bipartisan Infrastructure Law funding runs out in 2028.
One possibility is returning to a funding system that required homeowners to pay part of the cost of replacing the privately owned portion of their service lines.
“I don’t believe the city has the financial capacity to take on fully funding the private side replacement costs,” Pauly said.
That could present another challenge for a program designed to prioritize neighborhoods where residents already face financial disadvantages.
For now, residents living in homes with lead service lines that are not yet scheduled for replacement can take steps to better understand their own risk.
Julie LaRose, lead and nutrition program coordinator at the MacCanon Brown Homeless Sanctuary, runs one of the many programs in the city where residents can submit samples of their tap water for free lead testing.
LaRose recognizes residents’ concerns about their tap water. But she also emphasizes that Milwaukee water is highly regulated, and she has not seen any samples tested through her program exceed one part per billion (ppb) of lead.
That’s far below the FDA limit for lead in bottled water (5 ppb) and the EPA’s threshold for utility action (15 ppb).
“If you’re nervous about this, let’s test it,” LaRose said.

Marinette resident Andi Rich occasionally shows her anger over how elected officials don’t always seem to grasp the significance of PFAS-contaminated groundwater.
For years, Rich has kept up with the latest PFAS research and advocated for clean water in northeast Wisconsin.
“It is a complicated issue, but it’s frustrating that the people who were put in charge to figure it out … are failing to even understand the issue well enough to know how to do anything about it,” said Rich, a former candidate for the state Assembly.

Perfluoroalkyl- and polyfluoroalkyl substances, or so-called “forever chemicals,” have been linked to health issues, such as certain types of cancer, liver damage, thyroid issues and developmental effects or delays in children. The chemicals are used in a variety of manufactured goods, such as firefighting foam, nonstick coatings, textiles, carpeting and personal care products.
In Marinette County, PFAS thought to stem from Johnson Controls’ and its subsidiary Tyco Fire Products’ Marinette Fire Training Facility have contaminated groundwater used for drinking water.
This election season, candidates in state and national races on both sides of the political aisle are confronting voters’ growing concerns about the quality of their drinking water – in part because people like Rich have kept the heat on.
Widespread contamination
Throughout Wisconsin, PFAS contaminations have caught the attention of elected officials who say clean, safe drinking water is a critically important issue. A Wisconsin Department of Natural Resources study found 71% of 450 shallow, private potable-water wells sampled in 2022 contained at least one detectable PFAS. However, the authors note that “low percentages of samples” surpassed state (1% of samples) or federal (4% of samples) health limits for PFAS.
All of the state candidates who responded to the Northeast Wisconsin News Lab’s general election questionnaire in September said PFAS is a serious issue in Wisconsin.
Bipartisan support for PFAS-free drinking water motivated state Sen. Eric Wimberger, R-Gillett, to rewrite PFAS legislation in 2024 and 2025 to garner Democrats’ support. Assembly Rep. Jeff Mursau, R-Crivitz, co-authored the 2025 bill.
However, observers say it’s just the beginning of what’s needed.

Rich and other local clean water activists continue to push for state groundwater limits for PFAS and ways to prevent contamination, such as banning products containing the substances.
Marinette County’s contaminated area has expanded as biosolids containing PFAS were spread on lands, with the forever chemicals seeping into groundwater, Rich said. The contamination migrated with the groundwater’s flow into new areas, including into waterways that feed into the bay of Green Bay.
The DNR verified that the contaminated area has expanded, and agency experts discussed the size of the Expanded Site Investigation Area in Marinette County during a July listening session.
“The groundwater impacted by PFAS is extensive in this area and actions available to clean up PFAS will take a long time to achieve results,” said Alyssa Sellwood, DNR project manager for remediation and redevelopment.
While progress has occurred, including construction of new deep wells on private properties in a limited area, complaints about the new wells also are flowing as residents say water quality is an issue. The new wells are over 500 feet deep, Sellwood said.
“The water from that depth in this area can be very hard and contain naturally occurring contaminants like radium and strontium, which require treatment to lower the concentrations to levels that are safe to drink,” she said.

Piping in Lake Michigan water
The threat of PFAS making its way into other communities in northeast Wisconsin has encouraged some to connect to larger water systems. Officials in the city of Green Bay and Central Brown County Water Authority are selling their treated water, pulled from Lake Michigan, to nearby communities that have been using deep wells.
Making the move to a new system is costly, as residents of Pulaski learned. The village of Pulaski Board agreed to purchase its drinking water from the city of Green Bay, after years of relying on deep wells that produced water heavy in iron and other minerals, said Board Chair Keith Chambers. Water rates in the village could rise by as much as 230%, according to the village’s website.
In need of more water capacity, the board considered constructing two new deep wells and adding treatment facilities to two other wells to filter PFAS and other contaminants. Doing so would have been expensive and without a guarantee of high-quality water, Chambers said. Sediment from the minerals turned the water tan, and people complained about it, he said.
“We did not have any PFAS, but that can change in a heartbeat. Some could start leaching in. The DNR might change their threshold limits, or the EPA. You could have perfectly good water one day and the next day, they’re telling you it’s bad,” Chambers said.

The board opted to purchase water from the city of Green Bay, pulled out of Lake Michigan near Kewaunee and piped to Pulaski. The major construction project took longer than expected.
“We had two buildings we had to build and 6.5 miles of 20-inch pipe that we put in the ground,” Chambers said. “Right after COVID, prices were going through the roof; supplies weren’t available.”
The result is a substantial water rate increase. While the quarterly bill for 10,000 gallons was about $151, it is expected to rise to about $351, Chambers said. Ratepayers are footing most of the project’s cost, he said.
“Now there are a lot of people who are angry that we didn’t put it to a referendum,” he said. “I’m a big man, so it’s hard to tar and feather me, but if they could, they would.”
The estimated cost of constructing a new deep well was $20 million, he said, while the Green Bay water project ended up just north of $16 million. Grants from the DNR and city of Green Bay helped offset some of the cost.
In Wisconsin, the Natural Resources Board passed PFAS limits for community drinking water at the same level as the federal limits passed in April 2024. The board is expected to take up groundwater standards for PFAS in the near future, with a proposal to impose the same limits used for community drinking water.
What candidates say
Several candidates who responded to the NEW News Lab’s general election survey suggested phasing out use of the substances where feasible. Furthermore, they said funding is only one aspect of the issue that affects many Wisconsin communities.
“We need continued testing, help for communities facing contamination they didn’t cause and stronger prevention. I support holding responsible companies accountable for remediation costs while using state and federal resources when a responsible party can’t be identified,” said Emily Tseffos, a Democrat running to represent state Senate District 19.
Rep. Joel Kitchens, a Republican incumbent running for reelection in Assembly District 1, said the federal government should set PFAS limits for emerging PFAS varieties.
“There will undoubtedly be more contaminants that are currently unknown to us that will emerge, and I hope that the federal government will take a stronger role in addressing them. We are not adequately equipped at the state level to determine safe levels,” he said.
To fully address the problem will take more than the PFAS trust fund, Rich said. She’s still waiting for Wisconsin to set PFAS limits for groundwater.
“Everybody wants to point fingers and say somebody else should do it,” she said. “Maybe it’s time for our local representatives to actually try to do something about it.”
Gov. Tony Evers and state environmental regulators announced the launch of new grant programs Tuesday to help communities and private well owners address PFAS contamination.
Wisconsin regulators will conduct a full statewide review of the environmental impacts of data center development under a legal deal with environmental groups.

The Wisconsin Department of Natural Resources and a group of environmental organizations announced a settlement agreement Monday that would require stricter environmental impact assessments of future data center developments and initiate a statewide review of how data centers use the state’s resources.
In June, the Sierra Club and Midwest Environmental Advocates sued the DNR in Ozaukee County court, arguing that the agency approved the permits for Vantage’s massive data center currently under construction in Port Washington without conducting a proper environmental impact statement.
“AI data centers are massive, thirsty, energy hogs and have popped up all over Wisconsin,” Elizabeth Ward, director of the Wisconsin chapter of the Sierra Club, said in a statement. “They could completely change our landscape and use unprecedented amounts of water and energy. Wisconsinites and our regulators need to understand the impacts and opportunities to reduce harm before allowing data centers to move forward. Wisconsinites deserve an informed, transparent process for decisions that could shape their communities and environment for decades.
A report this summer by the state Public Service Commission found that the Port Washington data center and data centers being built by Microsoft in Mount Pleasant and Meta in Beaver Dam are set to be responsible for a 40% increase in statewide energy demand over the next six years.
As part of the settlement agreement in the lawsuit, the DNR will conduct full environmental impact statements of individual data center proposals moving forward and complete a statewide strategic analysis of how data centers consume resources.
State law and the DNR’s administrative rules allow the agency to conduct such an analysis when conflicts arise over resource demands for a “complicated or complex issue; an issue that is new to the state; an issue or policy that will likely lead to future department actions that will require an environmental impact statement; issues for which there is a high potential for legislation or new department policy and the planning and development of controversial resource-oriented projects.”
“What started as a lawsuit over the environmental review of one data center has become an opportunity to address the data center issue on a much bigger scale,” MEA attorney Michael Greif said. “Looking at these impacts holistically is important because the impacts of data centers are statewide. State regulators will now have to examine the cumulative impacts of data center development across Wisconsin.”
Wisconsin will become one of a few states assessing the statewide impacts of data centers on their resources. In July, New York Gov. Kathy Hochul signed an executive order that initiated a similar analysis and last December, the Maryland Legislature enacted a law that requires a number of state agencies to study “the likely environmental, energy, and economic impacts of data center development.”
State utility regulators have signed off on an energy developer’s proposal to build a pair of new natural gas power plants in southern Wisconsin tied to rapidly growing electricity demand from data centers.
The Wisconsin Department of Natural Resources sought approval in February of its program to oversee disposal of coal combustion residuals, or coal ash, from the state’s electric utilities. Wisconsin has six coal ash landfills that are owned by Dairyland Power Cooperative, Alliant Energy, Wisconsin Public Service and We Energies.
Coal ash is what’s left behind from burning coal at power plants to produce electricity. Metals or pollutants within that waste, including arsenic, lead and mercury, can contaminate groundwater without proper storage.
Anne Vogel, EPA’s regional administrator for its Chicago-based office, said the agency wants to eliminate duplicate regulation.
“It’s really about having to go to two different regulators and eliminating that barrier makes things more efficient, more cost effective for the management of these landfills in a protective way,” Vogel told WPR.
The state’s regulations must be at least as stringent as federal requirements, but they could be even more protective.
Wisconsin moved to streamline regulations under an update to rules for coal ash landfills in 2022, said Kate Strom Hiorns, director of DNR’s Waste Materials Management Program. Those changes incorporated 2015 regulations imposed by the Obama administration that addressed landfill design, groundwater monitoring and closure requirements.
“By submitting this and getting this program approval, it’s that recognition that our regulations are as protective as the federal regulations, and that the sites that are being regulated can be regulated for the most part solely under state regulators and inspections,” Strom Hiorns said.
Wisconsin utilities support a shift to one set of regulations for their coal ash landfills.
“Utilities in Wisconsin have been regulated by the state for many years; transferring this particular permitting authority from the federal to state government is a positive step for Wisconsin,” said Dairyland spokesperson Katie Thomson.
However, Cheryl Nenn with the environmental group Milwaukee Riverkeeper said she’s in favor of dual regulation.
“Given the changes in politics at the state level and the federal level, there’s some benefit to having that dual oversight,” Nenn said, highlighting the state’s adoption of federal regulations.
The Obama and Biden administrations strengthened coal ash regulations, including a 2024 rule that required oversight of inactive landfills. Under the Trump administration, the EPA has proposed rolling back and revising those requirements.
“They’d essentially remove or exempt a lot of these coal ash dump sites from regulation entirely, even though many of them are already showing evidence of groundwater contamination,” Nenn said.
Nenn said there has been groundwater contamination at the closed, unlined Cedar Sauk Ash Landfill in Ozaukee County that received coal ash from We Energies’ Port Washington power plant from 1969 to 1977.
Strom Hiorns said the state requires utilities to conduct groundwater sampling and has long monitored groundwater at closed coal ash landfills, which wouldn’t change under the federal proposal.
She said other landfills owned by We Energies and Alliant Energy have also exceeded preventive action limits or enforcement standards for groundwater. Those detections are tied to older parts of those sites or naturally occurring substances, such as boron or molybdenum.
Brendan Conway, a spokesperson for WPS and We Energies, said their landfills are actively monitored for groundwater impacts and managed in line with state and federal requirements. An Alliant spokesperson said it’s committed to full compliance.
Under the EPA’s proposal, Wisconsin would assume authority only for coal ash landfills. The EPA would continue to oversee coal ash ponds. The EPA is currently accepting public comments on its proposal to shift regulation to Wisconsin’s program. A virtual public hearing will be held Nov. 9.
The Wisconsin Department of Justice has reached a $245,000 settlement with a large livestock farm in Juneau County over allegations of manure polluting groundwater.
“Flush it and forget it” is easier for Wisconsin residents who are connected to municipal wastewater treatment systems. But there are more than 750,000 septic systems operating in the state. These privately-owned systems require regular maintenance and pumping.
If elected governor, Republican U.S. Rep. Tom Tiffany said he would audit spending at the Wisconsin Department of Natural Resources before considering any fee or tax increases to support fish and wildlife management.
Wisconsin environmental regulators have notified Enbridge of seven alleged violations of state environmental laws on a $1 billion project to reroute its Line 5 oil and gas pipeline in northern Wisconsin.

The Wisconsin Department of Natural Resources issued a notice of violation to the Enbridge Energy Company for incidents in Iron and Ashland counties, where the company is working on a controversial reroute of its Line 5 oil and gas pipeline.
The notice includes violations of permit conditions of the reroute construction project, and violations of state environmental laws for the unpermitted construction of a bypass around the Saxon Line 5 spill site. It covers laws involving state water quality, wetlands, navigable waterways, air quality, storm water and endangered resources protection.
The violations are alleged to have occurred from March 30 through Sept. 21 of this year. In August, a section of the pipeline leaked natural gas liquid near the town of Saxon, with drone video of the leak showing plumes of smokey vapor pouring out of an area where trucks and equipment were parked. Enbridge said that the leak occurred when an unoccupied truck rolled over an open excavation site near a valve project. Environmental groups fear that the leak could have been the largest of its kind in Wisconsin history.
The violation notice sets an enforcement conference, which is a standard step where the DNR and Enbridge will discuss the alleged violations. After the conference, the DNR can take further enforcement action such as issuing citations, referring the case to the Wisconsin Department of Justice for prosecution to seek forfeitures, or other court-related actions.
A DNR press release notes that the notice of violation is separate from Enbridge’s responsibility under the spills law to respond to hazardous substances which may have been released during the August leak.
“These allegations are numerous and serious,” said Clean Wisconsin Attorney Evan Feinauer in a statement. “The DNR must now use the full force of its enforcement authority to hold Enbridge accountable and secure relief that addresses the significant harm to our environment Enbridge has caused.”
