SURF's wastewater treatment plant has been working nonstop, treating over 10 billion gallons of water in the last 15 years to ensure a healthy downstream ecosystem. This #WorldWaterDay, we celebrate the science and stewardship behind every drop.

This week’s Photo of the Week, captured by Shelly Nisly, showcases a stunning frozen waterfall at Community Caves in Spearfish Canyon. Submit a photo for photo of the week to [email protected].

SURF is proud to partner with universities across the state including South Dakota Mines ➡️ This past weekend SURF scientists and educators attended the “Go To Mines” college recruiting event. Anyone of today’s incoming college freshmen could be future leaders at SURF!

Join us for Deeper Talks as SURF’s Bryce Pietzyk & Jason Connot share how they manage ventilation, dewatering & infrastructure beyond the 4850 Level. 📅 May 14 | 9am MT 🔗 Register for free: events.zoom.us/ev/Ajj4_nhN4yp…

By simulating the conditions deep inside the Earth, CUSSP is helping to advance enhanced geothermal systems—a technology that could make #geothermal power plants possible almost anywhere on the planet. Read more: sanfordlab.org/news/geotherma…

Maintaining SURF extends far beyond specialized science experiments. This discussion explores the behind-the-scenes efforts that are essential to creating a safe, healthy, and efficient environment for science to thrive. Watch the recording 👉 ow.ly/Jm5S50VXiZH

Today, we pause to honor and remember the brave individuals who gave their lives in service to our country. Their sacrifice is the foundation of the freedoms we enjoy every day, including the freedom to pursue knowledge, discovery, and innovation. #MemorialDay

The hunt for dark matter is going deeper—and colder. ❄️ While @LZdarkmatter leads the WIMP search at SURF, new tech like TESSERACT is targeting low-mass particles with supercooled sensors. 👀 Read more: sanfordlab.org/news/probing-n…

Welcome to the 2025 summer interns at SURF! Shown here from left to right are Zachary Spangler, Isabella Lopez, Olivia Cantrell, Nic Bearer, Siri Wing, Dylan Chase, Ollie Langley Peterson, Preston Drew, Grace Jenuine, Brooke Lammle, and Trinity Harford.

Last week, SURF interns and students from the Research Experiences for Undergraduates (REU) program visited the 1700 Level to explore advancements in underground safety and engineering with experts from @caterpillarinc!

Could going underground be the next step forward in quantum research? Underground labs like and SURF are ideal locations for testing technologies in low-background environments. Read more: sanfordlab.org/news/future-qu…

Join us tomorrow from 5–7 p.m. at Dakota Shivers Brewery for Pub Talks & Trivia! Last week’s full house enjoyed @fermilab’s “Physics Experiments You Can Do When You’re Bored at a Baseball Game.” Don’t miss what’s on tap this week—science, trivia & brews!

Big ideas often start underground around here. From hands-on experiences for students to cutting-edge research support, the SURF Foundation is investing in the next generation of scientists! Learn more 👉 sanfordlab.org/foundation #SupportScience #SURFFoundation

"I never imagined that studying particle physics would take me nearly a mile underground. This program gave me the confidence to pursue science in a whole new way," Madison Jilek, Davis-Bahcall Scholar and recent PhD graduate. sanfordlab.org/news/vision-fu… #SURFFoundation

Congratulations, @LZdarkmatter! LZ’s record-setting limits on #DarkMatter interactions, announced last year, have now been published in Physical Review Letters from @APSPhysics journals.aps.org/prl/accepted/1… #WIMPs

Each summer, SURF partners with Black Hills State on the U.S. National Science Foundation REU program, providing undergraduates with hands-on research experience. This year, Isabella Lopez from Georgia College & State University is diving into physics at SURF! Read more: gcsu.edu/artsandscience…

The CASPAR experiment at SURF has reignited plasma, a key step toward restarting after a multi-year pause. This underground accelerator helps scientists from University of Notre Dame and @SDMines study how stars create the elements that make up our universe. #CASPAR #DeepScience

At our next Deeper Talks, Dr. Kate Scholberg of Duke University shares how neutrino detectors around the world are preparing for the next big stellar event. Join us for this virtual talk on Wednesday, August 13 at 9 a.m. MT by registering for free at events.zoom.us/ev/Aj0TQRQsVpp…

ICYMI: The CASPAR experiment at SURF has reignited plasma, marking a key milestone on its path to restart. This underground accelerator helps scientists explore how stars forge the matter that makes up our universe. 👉 sanfordlab.org/news/caspar-ac…
