My impression is that in Southern California there is a negative correlation between the prestige of a school, public or private, and it's proximity to a freeway. In the San Fernando Valley, the well-known schools tend to be located near the 101 Freeway and the less prestigious schools are off in the hinterlands.
Indefinite social action indeed. The CDC states “No safe blood lead level in children has been identified.” Based on that logic, even if blood lead levels drop to ng/L or even pg/L, they’ll still be “too high.” Thank you for the very interesting post.
