The Stringfellow Hazardous Waste Site collection contains technical
reports, media clippings, correspondence, public records, ephemera, notes, government
publications, photographs, and other material regarding the Stringfellow Hazardous Waste
Site, a Class I industrial waste disposal facility in Glen Avon, California, that operated
from August 1956 to November 1972. Materials also document the community activism of Glen
Avon resident Ruth Kirkby. Topics covered by the records include site pollution,
contamination of local groundwater, local, state, and federal government cleanup efforts,
and the political activities of Ruth Kirkby.
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.
