Hinkley, California
unincorporated community in San Bernardino County, California, United States

Hinkley is an unincorporated community in the Mojave Desert, in San Bernardino County, California, United States, 14 miles (23 km) northwest of Barstow, 59 miles (95 km) east of Mojave, 47 miles (76 km) north of Victorville and about a 120-mile (193 km) drive northeast of Los Angeles, just north of California State Route 58. The residents have faced concerns over hexavalent chromium in their well water from the world's largest plume of this cancer-causing chemical.
History
Between the 1960s and 1980s, several miles west of Hinkley along State Route 58, the Hawes Radio Tower at the World War II Hawes Auxiliary Airfield, a guyed mast, was used for military communication in the LF-range.
In 2015, Hinkley was one of the filming locations for Sky. Hinkley was also the setting for Erin Brockovich.
Groundwater contamination
From 1952, Hinkley has had its groundwater contaminated with hexavalent chromium by a compressor station for natural gas transmission pipelines. Residents of Hinkley eventually filed a class action lawsuit against Pacific Gas and Electric Company (PG&E).
In 1993, Erin Brockovich, a legal clerk to lawyer Edward L. Masry, investigated the apparent elevated cluster of illnesses in the community linked to hexavalent chromium. The efforts of Brockovich and Masry, and the plight of the people of Hinkley, became widely known when the film Erin Brockovich was released in 2000.
After many arguments, the case was referred to arbitration with maximum damages of $400 million.
