Air Pollution

• 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 percent of houses in San Francisco County have a high risk of lead hazards. 

• Are there Superfund sites in your zip?  (In your BLOG, make sure to tell us what a Superfund Site is)

A Superfund site is an are in the U.S. that poses risks and considered as a candidate for cleaning because it was or has been contaminated by wasted hazardous chemicals. 
The Superfund site in my zip and in San Francisco is TREASURE ISLAND NAVAL STATION-HUNTERS POINT ANNEX. Overall, San Francisco ranked Cleanest/Best by some Superfunds sites. 

• What can you tell us about the Superfund sites that are near where you live?

The EPA Hazard Ranking System scores for TREASURE ISLAND NAVAL STATION-HUNTERS POINT ANNEX 

• What did you learn about the air quality in your zip code?

Here is what I discovered about San Francisco air quality

The pollution standards index is GOOD and the percentage of days with good air quality is 88%. This fact makes me proud. Top air pollutants in the area I live come from the airport and Golden Gate Bridge highway. 

• How about the water quality?

Regarding the water quality, I was upset to know that in Clean Water Act Comparative Rankings San Franciso water considered above the national average and dirty. 

SAN FRANCISCO County contains a portion of 3 watersheds:

San Francisco Bay

San Francisco Coastal South

San Pablo Bay

Interestingly, the leading source of water quality problems is in Urban Runoff/Storm Sewers, which seems justifiable due to the features of the landscape and geographic location. 

• How did your zip code fair on a social justice / environmental justice basis?

When I looked at Distributions of Environmental Burdens in San Francisco, I was surprised by the fact that in the distribution of burdens by race Whites ranked higher than people of color. Cancer risks are quite close in low and high-income classes. Overall, high income and highly educated population have lower rankings in most categories, which I found predictable as we have studied in MPH and MSBH programs. One of the most surprising facts I explored was that renters have lower risks in all categories compared to homeowners. I wonder why? Because of the inspection and regulations?
