This report summarizes the fracking jobs published this week at FracFocus, the industry-funded chemical disclosure instrument. It includes the Who, What and Where of recent fracking activity: the operating companies, the chemicals they use (including quantities), and where these jobs are located.

This report is produced by Open-FF, an open source, public service project to make the FracFocus data more usable. The nature of the fracking chemical data is complicated and can be difficult to make sense of; Open-FF aims to make it those data more digestible. In addition, FracFocus disclosures are plagued by inconsistencies, ambiguous and missing values and many obvious data errors; Open-FF flags and filters many of those problems. Our hope is that these reports give readers both big-picture perspectives of industry activities as well as enough detail to dig deeply into specifics such as individual chemicals, fracking job, or company.

Recognized Chemicals of Concern used in these disclosures

The following table is based on lists of chemicals that have health or environmental effects: SDWA, CWA, Proposition 65, PFAS and TEDX.

Explanation of columns in the index above
Column Description
CID is the chemical ID used in the disclosure table
CAS Number is the CAS registration number of the chemical. Click on the number for a summary of this chemical for all of FracFocus.
Chemical Name is one of the common names for the material
record count indicates the number of records in this week's disclosures. A given chemical may appear more than once in a disclosure
Largest mass is the single greatest mass of the chemical in this week's disclosures (in pounds)
% Rank of largest Mass how the largest mass from this week compares to the rest of FracFocus data (through last update). Ex. 95.0 means that this mass was in the top 5% of all uses ever recorded in FracFocus. If there are records with values of 90% or more, a list of all disclosures are in a table later in this report.
on_list indicates which of the following lists the chemical is on. Type the name of the list into the Search box to limit to those chemicals.
- CWA: indicates that the chemical is on the Clean Water Act list as compiled in EPA's CompTox
- DWSHA: indicated that the chemical is on the EPA's Drinking Water Safety and Health Advisory list
- TEDX: indicates that the chemical is on The Endocrine Disruption Exchange list
- prop_65: indicates that the chemical is on California's Proposition 65 list
- PFAS: indicates that the chemical is on EPA's comprehensive list of PFAS related compounds
- Volatile: indicates that the chemical is on the EPA's volatile chemical list

Proprietary labeling

FracFocus allows disclosures to hide the identity of chemicals that companies claim are business secrets. This practice has been controversial since the beginning of FracFocus. Some changes in format (the 'system approach') were made to purportedly reduce the use of proprietary claims. Nevertheless, they are still commonly employed. The following summarizes how much the past week's disclosures hid chemical identity with these claims. A detailed disclosure listing later in this report specifies the percentage of chemical records that are hidden by these claims for every disclosure. They range from zero percent to 70% or even more.

As of version 10, Open-FF detects proprietary claims by both the CASNumber and IngredientName fields.

Ingredient names used for proprietary records for this report's disclosures

Because these are proprietary claims, the reported ingredient name will not be specific, usually just a general class.

In some cases, companies do not report the PercentHFJob or report 0.0% for proprietary records. We use 0.0 pounds for those records in the following table.


Detailed disclosure listings

Notes:

Listing of chemicals in individual disclosures: In the table below, individual fracking disclosures are identified by APINumber. If you are interested in seeing the details of the raw data, use that APINumber at the FracFocus "Find a Well" site. That search site will serve pdf files of individual fracking events to your computer with most of the same raw data available used here. However, mass of chemicals is not available from these pdfs.

Maps: In the table below, a link is provided to a Google map/satellite view of the location provided in the disclosure (click on the APINumber). Many recently published fracking sites are newer than the satellite image that Google uses, so the well pad may not be visible. However, you can still view the geographic context of the drilling site.

"Silent" changes detected

FracFocus allows companies to change disclosures after they have been published. That includes changing individual data records in disclosures and even completely removing a disclosure. What these changes are and why they are made is not recorded, at least for public access.

Open-FF tries to detect such changes by comparing ALL current disclosures to an archive from the last download. The table below summarizes the changes detected since the last new-data was posted. Note that Open-FF currently checks only the major fields in the bulk download file for changes, not every byte.
