    • The second step involves using the calibrated aerosol monitor to identify distances from the fog release point where exceedances of the guidance levels occur. Testing of the Delta Hazer was conducted at ENVIRON’s testing facility and the Groton Dunstable Middle School Performing Arts Center, both located in Groton, Massachusetts.
