ODNR disputes study distributed by University of Toledo, linking radon to fracking
Wednesday, July 3, 2019
Since its publication and redistribution, a University of Toledo study that links the presence of radon in homes to proximity to fracking wells has been disputed by the Ohio Department of Natural Resources for using incorrect numbers in its evaluation.
The University of Toledo initially published its study midway through April. However, it wasn’t picked up by science and research websites, and even the Shale Gas Reporter, until the end of June. As its distribution spread, the data behind the study was questioned even less. It wasn’t until The Athens News took a closer look at the numbers to compose a local snapshot of the study that discrepancies were pointed out and the ODNR began working with the university to correct the errors.
After taking a closer look at the numbers referenced in the study, it’s clear they were predominantly derived from a singular source. The ODNR Division of Oil & Gas map the researchers pulled their data from contains accurate information; however, it doesn’t appear to have been read correctly.
From the map’s default view, only fracking wells appear to be marked. When you zoom in three times to take a closer look every well that has been permitted — even ones that have not been drilled — appears. One theory is that the University of Toledo researchers who worked on the study may have incorrectly counted the dots on the map, accidentally including more than just fracking wells in the data from which their study draws its conclusion.
If you’re interested in finding out more about fracking activity in your area, you can find up-to-date data on well drilling and permitting on the ODNR Division of Oil & Gas Resources Shale Well Drilling & Permitting page.

Shale FAQ
What is fracking?
Fracking is a slang term for hydraulic fracturing. Fracturing is a process by which highly pressurized fluid is pumped thousands of feet into the ground to fracture rock formations. The goal is to release the natural gas that’s locked inside the rock.
Is it safe?
What most concerns people about fracturing is ground water contamination. The worry is that fractures underground, caused by the process, will extending upwards and into aquifers, releasing gas and chemicals into the ground water supply. There’s been no confirmed reports of such a thing happening. Though surface spills and drill site blowouts can lead to localized environmental concerns.
Will my water catch on fire?
Flammable water is caused by the release of methane gas into a drinking water supply. Methane gas occurs naturally and can be released by any kind of drilling, including water wells. In Pennsylvania officials fined Chesapeake Energy $1 million for contaminating ground water with methane. It was determined that the company had not properly cemented it’s boreholes and gas migrated up the well, between rock and into aquifers.
