Utah Officials Probe Groundwater Discharge at Treasure Mountain Site
Utah officials are investigating groundwater dumping at Treasure Mountain demolition site, raising environmental concerns.

The Utah Department of Environmental Quality is currently investigating the Park City School District for allegedly discharging groundwater from the Treasure Mountain demolition site into a nearby creek without proper authorization. This investigation was initiated in mid-October following an anonymous tip that reported the district’s contractors had dumped potentially contaminated groundwater into Silver Creek, situated east of the demolition site. This incident marks the second environmental issue reported at the site, as the district had previously received a non-compliance advisory concerning asbestos management.
In response to concerns, the school district released a 14-page document detailing their procedures for asbestos management, air monitoring, and groundwater handling. The document stated that construction crews unexpectedly encountered groundwater during excavation activities, necessitating its management to ensure safety for ongoing work. An environmental consultant employed by the district conducted groundwater sampling, labeling it as 'non-hazardous.' However, officials clarified that this designation does not imply that the water meets drinking standards or is free from contamination, but rather that it can be disposed of through standard construction dewatering methods.
To manage the groundwater, the district's contractor installed a weir tank designed to separate sediments from the water. Despite this, on October 10, it was reported that contractors discharged groundwater directly into Silver Creek rather than using the tank. The district's report stated that pumps were reconfigured to bypass the weir tank and discharge water directly into the creek without prior treatment, which was not in compliance with established protocols.
The school district has not yet faced any fines or citations regarding these environmental issues, and the ongoing investigation by the Department of Environmental Quality is expected to yield results in early 2026. These findings will determine if any penalties are to be imposed and outline potential cleanup actions if deemed necessary.
