Blood, Trauma, and Biohazard Cleanup in Chalfant, CA

Chalfant, also called Chalfant Valley, is an unincorporated community and census-designated place in Mono County, lying in the Chalfant Valley at the western base of the White Mountains.

Chalfant was named after William Arthur 'Willie' Chalfant, who moved to the area in 1885 and went on to edit The Inyo Register newspaper for 55 years.

The Chalfant post office operated from 1913 to 1928, and the community grew up along the now-abandoned Southern Pacific Railroad line.

Chalfant sits on U.S. Route 6 about 14 miles north of Bishop, and most of its residents commute to Bishop for work and school; it shares Bishop's 93514 ZIP code.

Chalfant had a population of 660 at the 2020 census, living in 268 households that average 2.46 people, with about 83% of homes owner-occupied.

Despite having only 660 residents, the Chalfant CDP sprawls across 28.1 square miles at an elevation of about 4,260 feet, a density of just 23.5 people per square mile — and every resident is classified as rural.

On July 21, 1986, a magnitude 6.2 earthquake struck the Bishop–Chalfant area, injuring two people and causing an estimated $2.7 million in damage.

Chalfant's children attend schools in the Eastern Sierra Unified School District.
