Mold Testing in Moorpark, CA

Chumash people were the first to inhabit what is now known as Moorpark. A Chumash village, known as Quimisac (Kimishax), was located in today’s Happy Camp Canyon Regional Park. They were hunters and gatherers who often traveled between villages to trade. The village of Quimisac once controlled the local trade of fused shale in the region. The area was later part of the large Rancho Simi land grant given in 1795 to the Pico brothers by Governor Diego de Borica of Alta California.

Robert W. Poindexter, the secretary of the Simi Land and Water Company, received the land when the association was disbanded. A map showing the townsite was prepared in November 1900. It was a resubdivision of the large lot subdivision known as Fremont, or Fremontville. An application for a post office was submitted on June 1, 1900, and approved by August of that year. The application noted that the town had a railroad depot. The town grew after the 1904 completion of a 7,369-foot (2,246 m) tunnel through the Santa Susana Mountains. Moorpark was then on the main route of the Southern Pacific Railroad’s Coast Line between Los Angeles and San Francisco. The depot remained in operation until it was closed in 1958. It was eventually torn down around 1965.

Moorpark was one of the first cities to run off commercial nuclear power in the entire world, and the second in the United States, after Arco, Idaho, on July 17, 1955, which is the first city in the world to be lit by atomic power. For one hour on November 12, 1957, this fact was featured on Edward R. Murrow’s See It Now television show. The reactor, called the Sodium Reactor Experiment was built by the Atomics International division of North American Aviation at the nearby Santa Susana Field Laboratory. The Sodium Reactor Experiment operated from 1957 to 1964 and produced 7.5 megawatts of electrical power at a Southern California Edison-supplied generating station.
