Forest Service says leaking sewage plant did not contaminate groundwater near Holland Lake

The U.S. Forest Service has announced that monitoring wells installed along the north shore of Holland Lake this fall found that a leaking wastewater treatment plant did not impact groundwater in the area.

Earlier this year, the Forest Service discovered that one of the wastewater lagoons that serves a campground and the nearby Holland Lake Lodge was leaking more than legally permitted. Upon the discovery of the leak, the system was shut down and the USFS worked with the Montana Department of Environmental Quality to replace the lagoon liner and monitor the water quality around the site. USFS officials said in a press release last week that three monitoring wells were installed. 

“We always strive to protect our resources, and we are pleased that there is no evidence of groundwater contamination,” said Flathead National Forest Deputy Forest Supervisor Tami MacKenzie. “We also appreciate the guidance and cooperation of the DEQ as we move ahead with plans to improve the wastewater treatment system at Holland Lake that provides the opportunity for so many people to visit and recreate at Holland Lake.”
