Initial test finds 'forever chemical' in Mount Rushmore drinking water at level exceeding new limit • South Dakota Searchlight


A sample of Mount Rushmore National Memorial’s drinking water had levels of a “forever chemical” exceeding new limits established by the federal government.

Perfluorooctane sulfonic acid, or PFOS, is a member of the synthetic chemical group known collectively as perfluorinated alkylated substances, or PFAS. The chemicals have been used in industry and consumer products since the 1940s and don’t break down easily in the environment or in the human body. Research indicates PFAS exposure may be linked to negative developmental and reproductive effects, and an increased risk of some cancers.

A 2023 test of Mount Rushmore’s drinking water showed a PFOS concentration of 9.8 parts per trillion, more than two times higher than the Environmental Protection Agency’s new limit of 4 parts per trillion. The EPA finalized limits for several types of PFAS last month.

The result doesn’t necessarily mean Mount Rushmore is out of compliance with the EPA’s new rule, which will be implemented in phases. Current testing is preliminary. Tests won’t count toward the new limits until 2027, and the EPA will use annual running averages to determine compliance. The EPA won’t begin issuing violations until 2029.

Proposed EPA ‘forever chemicals’ regulation could cost SD millions for testing, cleanup

The current sampling is part of a multi-year, nationwide testing effort by the EPA. The South Dakota Association of Rural Water Systems is conducting a majority of the testing in the state.

In publicly available results published so far, Mount Rushmore is the only site in South Dakota to test above the new EPA limits for forever chemicals. Additional Mount Rushmore sampling results will be published in the coming weeks and months. Elsewhere in South Dakota, some of the chemicals have been detected at levels below the new EPA limits. 

PFAS from firefighting foam was previously known to have contaminated groundwater at military installations in or near locations including Rapid City and Sioux Falls, leading to mitigation efforts in those areas.

In an emailed statement, Mount Rushmore National Memorial spokesman Earl Perez-Foust said the National Park Service is monitoring the results and considering any mitigation that may be necessary.

“This could include treatment or considering a new water source,” Perez-Foust said. “Public health and safety is always our top priority.”

Reverse osmosis, granular activated carbon, nanofiltration and other methods have been identified as methods of removing PFAS from drinking water, according to the EPA.

The exact source of the contamination at Mount Rushmore is unknown, said Galen Hoogestraat, a hydrologist for the U.S. Geological Survey’s Dakota Water Science Center. 

“In general, PFAS sources can come from anywhere humans are interacting with the environment: food wrappers, water-resistant clothing, common products and waste,” Hoogestraat said.

For over a decade, Hoogestraat has studied perchlorate contamination in Mount Rushmore’s groundwater and local streams from former fireworks displays at the memorial. He said the amount of perchlorate in the water has “dropped substantially” in the last decade.

Hoogestraat said the memorial provides water to over 2 million visitors every year from a “very small postage stamp of an area in the Black Hills,” because the memorial is limited to using water from within the park boundaries.

That source is a fractured rock system that collects rain and groundwater, which makes it susceptible to contamination.

“There’s very little soil on top of the rocks, so there’s very little filtration of anything that comes from the surface — good or bad,” Hoogestraat said.

That can create volatile test results, since concentrations of contaminants can vary based on the seasons and weather conditions.

“There needs to be more sampling done to assess the variability around this,” Hoogestraat said, “and wrap our arms around the trends of this: Is this a long-term, persistent thing, or will this be variable over time?”

Laurel Hanson of Grand Forks remembered for her ‘patient, brilliant’ legal work

Laurel Hanson of Grand Forks remembered for her ‘patient, brilliant’ legal work


GRAND FORKS — Though at the time of her death it had been more than 15 years since Laurel Rae Hanson’s legal career ended, a longtime North Dakota Supreme Court chief justice and a federal magistrate judge still fondly remember her skill, passion and dedication.

“Laurel was patient, brilliant and a really good writer,” said Karen Klein, former longtime U.S. magistrate judge, now recognized as a settlement expert and mediation skills trainer. “I find it such a tragedy that her life was cut so short, and that she couldn’t carry through with the career that she so obviously loved.”

Hanson died on Feb. 21, at age 49.

She would have turned 50 on March 10. Her death came after nearly two decades spent combating various health issues, including osteoporosis and an injury that led to early retirement in 2009, when she was in her early 30s.

Former longtime North Dakota Supreme Court Chief Justice Gerald W. VandeWalle said he was sorry to hear about Hanson’s death, though he knew she was in poor health. He was her first mentor out of UND School of Law, and found her the perfect fit for the role of his clerk.

“She was an outstanding law clerk, as far as I was concerned,” VandeWalle said. “She certainly deserves all the respect I have for law clerks.”

Hanson’s mother, Barbara Hanson, said she wasn’t sure where her daughter’s career would have ended up if it hadn’t been cut short due to her health issues. Her career had just begun, but she did enjoy clerkship. After working for VandeWalle, Laurel Hanson moved on to a two-year position as Klein’s law clerk. She later took a permanent position when it opened.

The work of law clerks takes place primarily behind the scenes. They help judges review case files, researching and writing first drafts of decisions — a particularly important job, because decisions are expected to include detailed reasoning so everyone involved in a case understands what factored into a judge’s ruling, Klein said.

“If judges were to do it all from scratch, all by themselves, the backlog would just become unmanageable, and parties would wait many months — if not years — for decisions,” she said. “So it’s really important to have that legal expertise in someone other than the judge.”

Judges don’t control the cases assigned to them. While some are simple, others are highly complex — especially in the federal court system, where civil rights issues are handled, she said. Though Hanson’s career was brief, it had impact. Klein still recalls the work Hanson did researching and writing legal documents.

At a young age, she balanced what could at times be heavy work. Hanson was there when Alfonso Rodriguez Jr. was turned over to the federal court system and arraigned for the 2003 kidnapping and murder of 22-year-old Dru Sjodin, a case that made national headlines and created a tense atmosphere in North Dakota, particularly for women, Barbara Hanson said.

Laurel Hanson suffered a fall in 2008 that didn’t seem overly significant at the time, but led to an infection that caused further damage to already weakened bones, her mother said. She retired in 2009.

“I think she loved the law; she just loved delving into issues,” Klein said. “It was just a tragedy that she couldn’t continue.”

Whether dealing with highly controversial or straightforward cases, Laurel Hanson remained level-headed and fair, which are valuable skills for the job, Klein said. She valued Hanson beyond her professional abilities; they also discussed books and Hanson’s travels. She made an effort to embark on new experiences, such as skydiving and scuba diving.

“Things that some of us wouldn’t even dream of — she was willing to take them on,” Klein said.

Barbara Hanson agreed that travel and adventure were among her daughter’s passions, which also included animals, friends and family. During the summer of last year, she was ecstatic to become a great aunt.

“Laurel did so many things, and probably could’ve done more if she hadn’t run up against all her health problems,” Barbara Hanson said. “Laurel really loved life.”

Top prospect decommits from North Dakota, considering Michigan State


Recruiting never stops in the world of college hockey, and that trend has continued for Michigan State. A huge prospect has just re-opened his recruitment, and is back on the market, and the Spartans are in the thick of it.

Carson Pilgrim, a 5-foot-11 and 185 pound forward form Warroad (MN) has decommitted from North Dakota. The current Tri-City Storm star has the attention of many across the country, including MSU.

The Spartans have been listed alongside St. Cloud State and Colorado College as schools pursuing the top USHL prospect. He more than certainly will be donning a college sweater next year and Adam Nightingale wants it to be in the green and white.

Pilgrim has 16 goals and 19 assists in 42 games in the USHL this season.
