M3.4: Air Pollution

Zip code: 94132 San Francisco 

·       Who and what are the top polluters in your zip code?
·       What percent of the homes in your zip code have lead-based paint?
7% of houses in San Francisco County have a high risk of lead hazards
·       Are there Superfund sites in your zip?  
 A Superfund Site is any land that is contaminated and improperly managed which includes hazardous waste that has been dumped and left out in the open. These sites are identified by the EPA as in need of cleanup due to the risks the sites impose of human health and the environment. There is currently one Superfund Site in San Francisco County. This Superfund Site is the Treasure Island Naval Station-Hunters Point Annex.
·       What can you tell us about the Superfund sites that are near where you live?
This Superfund Site encompasses 522 acres of dry land and 414 acres submerged in the San Francisco Bay. Operations of the facility over many decades generated a wide variety of solid and liquid wastes, including paints, solvents, fuels, acids, metals, PCB’s, and Asbestos. This site is currently at stage 7 of cleanup: Construction Underway.  This stage involves the actual construction or implementation phase of Superfund site cleanup. This is reassuring that the site is underway for cleanup but still very concerning because it has been a site of hazardous waste since it was purchased from Drydock in 1869. Also the fact that it is partially submerged in the bay means that the chemicals and toxins have access to water and can easily be spread.
·       What did you learn about the air quality in your zip code?
Based on EPA’s most current data, this county ranked among the dirtiest/worst 10% of all counties in the US in terms of an average individual’s added cancer risk from hazardous air pollutants. This is concerning for me because I have had asthma since I was age 3 and I am assuming the air quality and pollution in San Francisco played a factor in my diagnoses.
·       How about the water quality?
San Francisco County contains 3 watersheds. 30% of surface waters in the area are impaired or threatened uses due to loss in water quality. There are 29 reports of water bodies with problems in attaining to water quality standards.
·       How did your zip code fair on a social justice / environmental justice basis?
Low-income communities and communities of color may suffer greater impacts from environmental degradation than other groups.Toxic chemicals have a greater release rate where low income families live. This is very concerning and more needs to be done to protect vulnerable populations who are exposed to more harmful chemicals.

  1. That is mind blowing that 7% of houses in San Francisco contain lead. I understand that most houses are old, but wow. When I did my ScoreCard, all I could think about was the different communities that live within my county (San Mateo) and I feel like that is similar to your county as well. There are so many different neighborhoods in San Francisco and I wonder if the amount of toxic chemicals changes based on those neighborhoods. Thank you for the great information!

  2. Hello Marisa,
    I am surprised by Chevron - and very disappointed. I don't use their gas, but I'm sure you've heard the commercial - Chevron keeps your engine clean. However, it seems that their products are harming the environment with over 11,000+ pounds of gunk. In addition, knowing how San Francisco is clustered it wasn't surprising that the air quality is horrible. One positive is that the Bay is absorbing the carbon dioxide, but on the flip-side it is killing the marine life. It brings up the question of how much longer will we continue to destroy the environment?

  3. Hi Marisa,

    Like yourself, I was very surprised to find that low-income and communities of color are suffering from environmental injustices. In an area that is proclaimed as one of the most coveted American communities to live in, I'm surprised to find that we have high amounts of pollutants and are unjustly distributed.
