Map of census tracts surrounding the Salton Sea, colored by CalEnviroscreen population characteristics, which represent biological traits, health status and community indicators that can increase vulnerability to pollution.

Nearly all census tracts in Imperial County scored rank among the top 20% of census tracts most vulnerable to pollution.
