EPA's disclaimer for the Hazard data¶
The Hazard Comparison Dashboard is a prototype tool and a compilation of information sourced from many sites, databases and sources including U.S. Federal and state sources and international bodies that saves the user time by providing information in one location. The data are not reviewed by USEPA – the user must apply judgment in use of the information. The results do not indicate EPA’s position on the use or regulation of these chemicals.
Elsner and Hoelzer Structural Groupings¶
We adopt a classification scheme based on the work of Elsner and Hoelzer (2016), which organizes chemicals primarily by their core molecular structure and key functional groups, organizing by large classes such as Alcohols and Inorganic Chemicals. Within most of these broad classes, chemicals are further grouped into subgroups sharing more specific structural similarities. See an overview and index of these groups and their details.
For FracFocus materials that were not classified in Elsner and Hoelzer (2016), we used a chatGPT reasoning model to assign an appropriate Elsner and Hoelzer classification. If that was necessary, the model's justification for its classification is given below.
Level 1: Alkoxylated Alcohols --- Level 2: unspecified/other¶
ChatGPT justification for classifying decision:¶
**FG** Alkoxylated Alcohols;unspecified/other The chemical "C12-15 ethoxylated propoxylated alcohols" contains both ethoxylated and propoxylated groups attached to an alcohol backbone. Since the available categories under "Alkoxylated Alcohols" specify single types of alkoxylation (either ethoxylated or propoxylated) and do not account for multiple alkoxylations on the same molecule, the most appropriate classification is "Alkoxylated Alcohols;unspecified/other."
General frequency of use¶

|---|---|---|---|
| Num disclosures | 1,215 | 1,135 | 1,091* |

Where this material has been reported¶
FracFocus records that have conflicting or non-standard location data are not included in this map. This includes many records in Alaska.
Detailed Uses¶
Each "use" below represents a single record in a disclosure, that is, a single line. A given disclosure may have more than one record of a particular chemical.
Using all filtered data for this chemical.
Uses by percent of the fracking job¶
This measure roughly shows a comparison of the concentration of the chemical in the whole fracking job (including the base fluid which is typically over 80%). Only the disclosures where the sum of PercentHFJob is within 5% of 100% are considered "valid."
PERCENTILES: -- 25%: 0.0004125 percent -- 50%: 0.00189 percent -- 75%: 0.00271 percent -- max: 0.12884 percent
Uses by mass¶
This measure shows a comparison of the absolute quantity of a chemical used in a fracking job.
Number of records with a mass (blue circles): 1,091
Number of records without a calculable mass (orange bars): 45
mass PERCENTILES: (represented by lines in the figure) -- 25%: 472 pounds -- 50%: 2,142 pounds -- 75%: 3,978 pounds -- 95%: 10,239 pounds -- 99%: 16,151 pounds -- max: 37,920 pounds
Which suppliers are most frequently named for this chemical?¶
The field reported below is bgSupplier.
Which primarySuppliers are most frequently associated with this chemical?¶

Raw fields for this chemical¶
These are the fields in the raw FracFocus data as they are entered for the records positively identified as this chemical. These raw fields often have typos, variations on a chemical name, etc. In some cases, two variations may seem identical, but probably differ by non-printing characters.
Shown are operators and how many records without mass, as well as the types of information missing or in error for each company. In addition, not all disclosures are curated by Open-FF yet.
