Fresno Is America’s Dirtiest City

Fresno is America’s dirt­i­est city. Forbes mag­a­zine says Fresno is at the top of their annual list this year. The mag­a­zine says the Cen­tral Val­ley suf­fers from some of the worst air in the nation and a poor water sup­ply. It also cites the Valley’s geog­ra­phy as a fac­tor because the Val­ley acts like a giant bowl that traps a lot of pollutants.
