The Department of National Defence continues to investigate the discovery of harmful chemicals in the area of CFD Mountainview in Prince Edward County. The DND has been working since spring of 2021 to address the issue after per- and polyfluoroalkylated substances (PFAS) and benzene were discovered near the landfill at the detachment. The PFAS on the property are thought to mostly be related to the past use of firefighting foams for training while the benzene may be the result of past fuel use storage practices.
