MARQUETTE — The public is invited to a presentation regarding environmental activities at the former K.I. Sawyer Air Force Base, which will begin at 1 p.m. Wednesday at the K.I. Sawyer Heritage Air Museum.

The museum is located at 402 Third St. at Sawyer.

The first hour of the program will be reserved for a presentation, with the remaining time set for a question-and-answer period.

Jeremy Bennett, project manager at CTI and Associates, based in downstate Farmington Hills, said contractors have been performing work at K.I. Sawyer.

Nest week’s event will focus in part on a remedial investigation for PFAS at Sawyer International Airport and surrounding properties.

The Environmental Protection Agency has indicated that scientific studies have shown that exposure to some PFAS — per- and polyfluoroalkyl substances — might be linked to harmful health effects in humans and animals. PFAS have been used in fire-extinguishing foam among other uses.

Bennett said a remedial action has been ongoing at two sites for petroleum impacts at the airport. Those sites have had restrictive closure, he noted, but the goal is to get regulatory closure on the sites, meaning there would be no liability and they could be developed.

“No human health risk at all is what we’re trying to get to,” Bennett said.

The U.S. Air Force is putting on the Wednesday presentation, he said, with the USAF having put on such events for years.

CTI is an environmental consulting and engineering firm specializing in delivering environmental remediation, engineering and construction to local, state and federal government agencies, as well as institutional and private sector clients.
