I was reading yesterday an article from the LA Times by Hector Becerra stating that three of the ten most polluted ZIP codes in California are from the Los Angeles County. The top three places on the list of polluted ZIP Codes were all in the San Joaquin Valley: Fresno, Bakersfield and Stockton. In fact, two of the most polluted ZIP Codes were in Fresno and three were in Stockton. Once I finished reading this, I asked myself a question: Why am I not surprised?
