Summary: Chemical records in FracFocus range from less than one pound to over 1 million pounds. Disclosures that fail to report quantity data obscure a critical piece of information. Open-FF found that Ohio had 595 such disclosures by 24 different operators. Only a handful of Ohio operators are responsible for the majority of affected disclosures.
Background on chemical quantity omissions
- The national disclosure instrument, FracFocus, documents the fracking chemicals that have been used in over 220,000 fracking jobs in the US since 2011. This extensive data set is especially important because it is one of the few resources available to the public about fracking chemicals. As such, FracFocus should be central to analyses and debates about fracking patterns and impacts. However, poor data integrity can undermine the usefulness of this resource.
- The Open-FF project is trying to make errors in FracFocus more visible to stakeholders. Our aim is to alert users of FracFocus data to weaknesses and to encourage operators to correct problems and prevent future errors.
- Fracking chemical quantities reported in FracFocus can range from less than one pound to over one million pounds. Open-FF has found that data records for chemical quantity are incomplete in over 35,000 disclosures and more are added monthly. These FracFocus data omissions prevent users from understanding the scope of the environmental and public health risks associated with hydraulic fracturing operations.

The scope of Ohio’s data omission issue
As of this date, Ohio has 3,359 disclosures in FracFocus. We have detected records with omitted quantities in 17.7% of those disclosures. The following figure illustrates Ohio’s pattern over time.
The following table summarizes the operating companies with affected disclosures in Ohio. To see examples of data omission, follow “Link to Report” for summaries of specific companies. On those pages, you will find lists of the chemicals that haven’t been fully reported.

As of this date, many companies continue to publish disclosures without full quantity data.
Quantity omissions in Open-FF data sets
For Open-FF data sets, although we detect and flag omitted data, we do not attempt to fill it with estimated values. Instead we leave the values as “no data” so that any aggregate calculations are not compromised by data not directly reported by the industry. In cases in which a user wishes to use an estimate, we suggest using the median PercentHFJob value for that chemical as a proxy. From there, a mass can be calculated from the “job_mass” in the data set.
