Naturally-occuring asbestos fibers

Background

Asbestos fibers occur naturally in the soil in 44 of California's 58 counties.

In the summer of 2004 naturally-occurring asbestos was discovered in Folsom at the proposed site of Lago Vista High School.

The Sacramento Metropolitan Air Quality Management District (AQMD) has regulatory authority over Naturally-occurring Asbestos (NOA) and created this page as a resource to keep the public current on developments in Folsom and provide links to helpful information about asbestos in general.
