FracFocus has become the largest registry of hydraulic fracturing chemical disclosures in the US. The database, available to explore online and download in bulk, contains disclosures from fracking operators; it details the location, timing, and water volume of each fracking job, plus the names and amounts of chemicals used. The project is managed by the Ground Water Protection Council, “a nonprofit 501(c)6 organization whose members consist of state ground water regulatory agencies”.
