Below is a list of all the sampling results that have been taken around the Stony Hollow landfill. Initially, RAPCA and Waste Management began taking samples on peak odor days until Ohio EPA ordered Waste Management to begin a 1-in-6 day sampling schedule in December 2016. Ohio EPA then ordered Waste Management to begin a 1-in-3 day sampling schedule in May 2017. This sampling concluded in April 2018. All sample results were reviewed by an Ohio EPA toxicologist and were determined to be below the risk-based screening levels that indicate a hazard to human health.
In May 2017, RAPCA began a community sampling project near the landfill. The results are available on the Community Monitoring Project page.
