Title: Why Marin County Has The Highest Breast Cancer Rates In The US
Headings: 

Content: The deepest part of San Francisco Bay is offshore  from Marin, and the highest volume of sediment-laden water passes through  this area each day with the tides. The lowest breast cancer rates are along  the Pacific coastline of Marin. The spatial distribution of breast cancer  made it clear that there had to be an environmental cause. Large areas  of mudflats and estuaries along the bay side shoreline of Marin, like the  Welsh seacoast, provide a low energy environment for radioactive contaminated  fine sediments to settle out. CONTAMINATION OF REGIONAL WATER SUPPLIES
Most of the fresh water coming into San Francisco Bay  is from the Sierra Nevada Mountains east of the California coastline, a  very high mountain range running north and south along the border with  Nevada. The soils of the Sierras are now contaminated with radioactive  materials from nuclear bomb testing, Chernobyl, and the emissions from  the Rancho Seco nuclear power plant, which operated east of San Francisco  until it was shut down in 1989. Most of the drinking water for the San  Francisco Bay area comes from the Sierras. Approximately 95% of the radioactive  emissions from Rancho Seco were rained and snowed out into the Sierra Nevada  Mountains. During the lawsuit, which eventually shut down Rancho Seco nuclear  power plant in 1989, the citizens who owned the Sacramento municipal power  company contracted with Lawrence Livermore nuclear weapons lab to measure  fission product emissions in the Rancho Seco environment. I obtained the  Livermore radiation reports and communications with lawyers, from Dr. Ernest  J. Sternglass who had been an expert witness on the lawsuit.
