	Primary Tables Use these to zero in on specific chemicals, areas or companies. Links in these tables take you to more detailed pages.
Chemical Index	All reported chemicals used in FracFocus. Includes summary statistics, hazard summaries and links to in-depth analysis of each material's use.
State Index	Fracking activity by county, operator, and a profile of proprietary chemical uses. Links to detailed county maps and analysis.
Operator Index	Table summarizing all Operator companies and links to details of every Operator company's location, active years and chemicals of concern.
Supplier Name Table	Table listing all names in the Supplier field and the corresponding bgSupplier name to facilitate searching.
	Overviews
What is Open-FF?	A brief description of the Open-FF project.
FracFocus summaries	A big-picture summary of FracFocus data including where, when and what companies were active, water and proppant use.
	Other Resources
Chemical synonyms	Searchable table that lists alternative names for the chemicals published in FracFocus.
CAS-Ing pairs	Searchable table to help users see how the raw FracFocus fields CASNumber and IngredientName were curated into the Open-FF bgCAS values. This curation is necessary because there are many correctable mistakes that, once fixed, give us a more complete record of chemical use.
Data Dictionary	This dictionary has three tables: The first table describes the fields in the original FracFocus bulk downloads and the generated fields in the Open-FF data sets. The other tables provide information about the process of identifying the carrier records in disclosures.

Many tables are interactive. You can:

• re-sort the table by clicking on a column heading
• click there again to reverse the table order (from ascending to descending)
• sort by more than one column (clicking them in succesion) to facilitate finer sorting
• filter the records that are displayed by using the search box (for example, type in a company name to only show those records)
• control the number of records shown per page
