California's new pollution map

In the new interactive map of pollution effects analyzed by zip code, the darker colors represent the worst cases. Notice the line of dark blue running the whole length of the Central Valley. America's breadbasket, as they say. The analysis takes into account air quality, pesticide use, groundwater, and traffic density as well as population and socioeconomic data. The map is by Cal EPA, where you can play around with it interactively. Here's the underlying report and a short item at Atlantic Cities.
