I grew up in SF/Bay Area late ‘60s to mid ‘90s. I have inexplicably high levels of uranium. Perhaps it was the high levels coming from the water supply in Hetch hetchy which is a granite lined natural reservoir. Or, perhaps it was this. Any oldfags with additional insights on this?
Thanks. Forgot about that. Took a couple of field trips there as a kid in early ‘80s. Lived about 30 miles away. Were they contaminating the water? Digging to see if they had any accidents. Lived near SLAC too. They always had environmental cleanup issues.
