This map shows the water quality of different cities and regions in California, with green representing fair, red representing at risk, and grey representing no data. Majority of the state shows red, specifically the central valley region. Green areas are located around more urban and developed regions, like the Bay Area, San Francisco, and San Diego. If we look at an average income map of California, we see that the regions with a lower average income include the Central and Imperial Valley, which shows how places that are more rural and underdeveloped regions have lower water quality, while richer, and more developed areas around major population centers have better water quality, as they take priority.
