El Dorado County, officially the County of El Dorado, is a county in the U.S. state of California. As of the 2010 census, the population was 181,058. The county seat is Placerville.
El Dorado County is part of the Sacramento-Roseville-Arden-Arcade, CA Metropolitan Statistical Area. It is in the historic Gold Country in the Sierra Nevada.
El Dorado County's population has grown as Greater Sacramento has expanded into the region. In the county's unique Lake Tahoe area, environmental awareness and environmental protection initiatives have grown along with the population since the 1960 Winter Olympics, hosted at Squaw Valley Ski Resort in neighboring Placer County.
The present-day site of El Dorado County was once home to the Maidu, Washoe, and Miwok Native American tribes, and is notable for being the site of the 1848 gold discovery that sparked the California Gold Rush. The County of El Dorado was one of California's original 27 counties created effective February 18, 1850 (the number has risen to 58 today). Its name is derived from the Spanish meaning "the gilded/golden".
The final segments of the Pony Express mail route ran through El Dorado County until its replacement with the telegraph service in 1861; U.S. Highway 50 follows the Pony Express route today.Mother lode

Portions of El Dorado County are known to contain natural asbestos formations near the surface. The USGS studied amphiboles in rock and soil in the area in response to an EPA sampling study and subsequent criticism of the EPA study. The study found that many amphibole particles in the area meet the counting rule criteria used by the EPA for chemical and morphological limits, but do not meet morphological requirements for commercial-grade-asbestos. The executive summary pointed out that even particles that do not meet requirements for commercial-grade-asbestos may be a health threat and suggested a collaborative research effort to assess health risks associated with naturally occurring asbestos.
