In December of 2017, the district relayed test results to parents that it received from its environmental consultant, Nova Environmental, "The most recent surveys were conducted from December 26-29 at Delta Kelly, McGregor, Musson and University Hills Elementary Schools, and Rochester High School... The survey results at Delta Kelly, Musson and University Hills Elementary Schools and Rochester High School indicate all radon samples collected are significantly less than the EPA action level of 4.0 pCi/L. One sample in the boiler room at McGregor Elementary warranted further investigation. After retesting, it was determined that the sample was also below the action level set by the EPA. Nova Environmental, Inc., recommends that no further action is necessary at this time for these buildings." D In Clawson and Ferndale school districts, radon testing hasn't been a regularly scheduled item. However, Jamie Stottlemyer, executive director of operations and transportation for the two districts, said plans are underway for Nova Environmental to conduct testing at both of the districts this summer. In December of 2017, the district relayed test results to parents that it received from its environmental consultant, Nova Environmental, In the South Lyon Community School District, 14 of the district's buildings were tested in 2012 at random locations. Those buildings included seven locations in each of the district's high schools, five locations in each of the middle schools, three locations in each of the elementary schools, two locations in the administration building and early childhood center, and one location in the grounds operations center. In each case, short-term activated charcoal devices were used to measure radon levels. "During the entire measurement period (typically two to seven days), the absorbed radon undergoes radioactive delay," Arch Environmental wrote in its 2012 report. "Arch Environmental Group deposited the AC detectors on March 22-23, 2012. The detectors were placed between knee and shoulder heights on a flat or hanging surface. Additionally, the detectors were placed at least one foot from exterior walls, three feet from windows or doors, away from direct sunlight and away from heat vents." The testing also included duplicate test devices, as recommended by the EPA and as is the case in each of Arch Environmental's testing procedures. The results show that all of the samples had concentrations below the EPA's recommended action level of four pCi/L. Page 4
