California Senate Bill 702
In October 2001, Governor Gray Davis signed the California
Senate Bill 702[external link] (Chapter 538, Statutes of
2001). This bill made California the first state in the nation to begin
planning a statewide environmental health tracking network for chronic
diseases and environmental hazards and exposures in order to monitor
trends in health conditions, such as asthma, cancer, birth defects,
learning disabilities, and neurological disorders such as Parkinson's
and Alzheimer's, which have suspected links to environmental exposures.
