  This is pretty interesting, thanks. I'm not really strong in stats, but it seems like many of the non-contaminated counties have very low sample sizes that may not be statistically significant. Example: in Marin County, 0 of 11 samples were found to be contaminated. In Alameda, 2 of 73 samples were contaminated. Maybe someone else can comment?
