Located in Riverside County approximately five miles northwest of the City of Riverside and one mile north of the community
of Glen Avon, the Stringfellow Hazardous Waste Site occupies 17 acres at the head of Pyrite Canyon in the Jurupa Mountains.
Commonly referred to as the Stringfellow Acid Pits, the site functioned as a Class I industrial waste disposal facility permitted
by the Santa Ana Regional Water Quality Control Board (RWQCB) from August 1956 to November 1972. In 1955, the RWQCB contacted
James B. Stringfellow, owner of the Stringfellow Quarry Company, to discuss the creation of an industrial waste dump on a
portion of his company's land in the Jurupa Mountains. Following a report by the State Division of Water Resources approving
use of the site, Stringfellow agreed to the proposal, and the dumping of toxic wastes commenced in 1956. Approximately 34
million gallons of industrial wastes, which belonged to some of the most high-profile American companies and contained over
200 hazardous chemicals, were disposed of over the course of the site's 16-year operation.
