South Frontenac is part of the KFL&A region, one of the areas with the highest documented indoor radon levels in Ontario. A regional study conducted by KFL&A Public Health tested 1,047 homes and found that 21% exceeded Health Canada's guideline of 200 Bq/m³, while 52% exceeded the World Health Organization's recommended level of 100 Bq/m³. Public Health reported that the percentage of homes with elevated radon was nearly five times the provincial average, reinforcing the importance of testing every home regardless of its age, construction, or location.
