- Our monitoring results demonstrate that the whole house filters have been very effective and have reduced all affected homes to well below the Michigan criteria and federal advisory of 70 ppt for PFOA/PFOS.
- Homes are retested on a set schedule based on each home’s prior PFOA/PFOS test results. Monitoring schedules range from weekly monitoring for homes with the highest concentrations to annual monitoring for homes with PFOA/PFOS concentrations at or lower than 70 ppt.
