Why is this important?

Save The Bay has worked to make it safer for people to fish for food from the San Francisco Bay. Studies have shown that seafood from the San Francisco Bay contains contaminants, and warnings have been issued about the amount of fish to eat from the Bay per month. Unfortunately, many low-income people, especially Asian-Americans, African Americans, and Latinos, depend upon the Bay as a source of food. What can you do to make eating from the Bay safer for people?

This action project begins with learning about issues that affect the water quality of San Francisco Bay, such as non-point source pollution and toxic hot spots, and finding out who fishes from the San Francisco Bay and what fish they are catching and eating from the Bay. The action project is to develop ways to help protect people who fish from the Bay now, and to ultimately improve the water quality of the Bay so that in the future people can safely eat fish from the Bay.


Timeline

This activity will take some research time (a total of 3 or 4 hours), mainly using the internet and free materials that you have to order from organizations (order these materials now, so you will have them when you are ready to research). After conducting the research, the amount of time spent taking action is up to you, from an afternoon painting storm drains to a weekend spent at a fishing pier.

Order a copy of Estuarywise from the San Francisco Estuary Project. Contact Liz Blair to request your free copy.

Taking Action

Who Dirtied the Waters?
The first step in this project is to determine what pollutants are currently in the Bay, and where they came from. To do this, a little research is required. Check out the following web sites (it's a lot of reading, try skimming some of the articles for the important information).
www.abag.ca.gov/bayarea/sfep/reports/soe/soe7a.htm
www.abag.ca.gov/bayarea/sfep/reports/fact/pollute.htm

Find answers to the following questions:

  • What is the definition of a pollutant?
  • What are some of the pollutants in the Bay?
  • What are some of the ways that these pollutants got into the Bay in the past and what ways are they entering the Bay now?
  • What is urban runoff?
  • How do these pollutants end up in the animals of the Bay?

A great activity to demonstrate how our Bay has ended up such a mess is to simulate the history of pollution.

You need these materials: clear, 1 gallon or so, wide-mouth container filled with tap water, 15 film canisters with masking tape labels and materials inside (listed below), and a stir stick.

Film canisters:

  • Labels
    Materials inside
  • River
    Sand
  • Wetlands
    Dry Grass
  • Shellfish
    Crushed Shells
  • Ohlone and Miwok
    Crushed Shells
  • Settlers
    Organic Garbage
  • Gold Rush
    Soil
  • Farmers
    Soil
  • Houses
    Toilet Paper
  • Port
    Vegetable Oil
  • Factories
    Vinegar
  • Landfills
    Small bits of plastic garbage
  • Cleaning
    Baking Soda
  • Agriculture
    Drops of food coloring
  • Cars
    Vegetable Oil
  • Soap
    Dishwashing Soap

Hand out the film canisters and ash; one for every one or two people. Have one person read the following story. When the characters from the film canisters are mentioned, they should pour the contents of the film canister into the water container and give it a stir.

Once upon a time, there was a beautiful bay. Freshwater flowed down from mountains and hills and ocean water came in from the ocean. The fresh and salt water mixed, forming an estuary that teemed with wildlife. The tide came in and out. Fish swam in the bay, mud creatures burrowed in the mud, plankton floated through the water, thousands of birds flew overhead, grizzly bear and tule elk waded through the wetlands.

A river flowed into the Bay, carrying sediment that settled to the bottom, forming homes for plants and animals.

  • Wetlands surrounded the bay. Decomposing plants from the wetlands were carried into the bay with the tide, providing food for fish and mud creatures.
  • In the mud below the shallow water, shellfish such as clams, mussels, and oysters grew.
  • Ohlone and Miwok people lived around the Bay, feeding on the shellfish in the Bay.
  • Settlers arrived from Spain and built missions around the Bay. Some of their organic garbage ended up in the Bay, which they named San Francisco Bay.
  • In 1849 gold was discovered and thousands of people rushed to California. Gold mining in the mountains caused massive amounts of sediment to be washed down rivers to the Bay. Much of the sediment contained mercury, which was used to separate the gold from the sediment.
  • The towns around the Bay grew and farmers planted crops to feed the growing population. Soil from the fields ran into the Bay with the rains.
  • More and more houses were built. Towns grew into cities. Pipelines were constructed to remove sewage from homes and pour it into the Bay.
  • The Bay grew into a major port, where large oil tankers and cargo ships came to unload their cargo. Tankers spilled oil into the Bay.
  • Factories built along the water's edge dumped their wastes and chemicals into the Bay.
  • Everyone's garbage ended up in landfills built on top of wetlands. Garbage from the landfills was blown into the Bay.
  • People cleaning their houses used toxic cleaners and drain openers. Thankfully, sewage treatment plants now cleaned the wastewater from homes, but heavy metals from cleaners flowed on into the Bay, unable to be removed by the treatment plants.
  • Agriculture became a huge business in California. Much of the state's water was used on fields. Some of the water flowed back into the Bay, but contained fertilizers and pesticides used on the fields.
  • Freeways were built around the Bay, and millions of cars dripped motor oil onto the roads and parking lots. With the rains, the oil flowed into the Bay.
  • Car owners washed their cars with soaps in their driveway. As they hosed off the soap, it flowed down the storm drain into the Bay.

Questions for thought:

  • Would you eat fish from this Bay?
  • Who dirtied the Bay?
  • Who is responsible for cleaning it up?
  • Who is Fishing for Food?

The second step is to find out what fish are being caught in the San Francisco Bay, what the health warnings are, and who is eating fish. Use the following web sites. Also, use the Save The Bay materials that you: Fish Consumption brochures, Save the Bay's report, Fishing for Food in San Francisco Bay: Part II, and a poster and video that demonstrate safer fish consumption.

www.sfei.org/rmp/posters/fishcontam/index.htm http://www.oehha.ca.gov/scientific/fish_doc.htm
at this site, click on Interim Health Advisory for San Francisco Bay (English) or on one of the advisories in another language (it is available in Spanish, Cambodian, Chinese, Korean, and Vietnamese).
www.oehha.ca.gov/scientific/fish/99fish.htm http://www.oehha.ca.gov/scientific/fishup99.htm

Find answers to these questions:

  • What is the current health advisory for eating fish from the Bay (number of fish per month)?
  • What are some ways that people who eat fish from the Bay can reduce the health risks?
  • What people eat the most fish from the Bay (ethnic background, sex, age, etc.)?
  • Why does pollution most affect animals at the top of food chains (such as people)?


How can we Save the Bay?

Now that you have learned about the health hazards of fishing for food from the San Francisco Bay, it's time to take action to protect the water of the Bay and the people who depend on the Bay as a source of food. There are many things you can do to save the bay. Look through the book Estuarywise for some initial thoughts. Brainstorm about ways to improve the Bay's water quality. Below are two action projects you can undertake to improve water quality and to educate people who eat fish from the Bay about health warnings.

1) Label storm drains in your neighborhoods with warnings—"Do Not Dump, Flows to Bay". Contact your county's Public Works department or Stormwater Program to get stencils and further information about stenciling (such as what storm drains need stenciling, how to stencil, and how to be safe).

After labeling the storm drains, let your neighbors know by distributing brochures, either brochures from the Public Works department or brochures that you create and photocopy. These brochures could let people know what you have done and that only rain should flow down storm drains.

2) Visit a fishing pier near you and set up a table on a weekend with brochures and signs describing the health warnings and how to more safely eat fish from the Bay. Get extra brochures and posters from Save The Bay. Be sure that you have a number of people working with you at the table for safety.

While you are working at the table, conduct a survey of fisherpeople. Find out their age and race/ethnicity, how many fish they eat each week or month, and what types of fish they eat. Also ask whether or not they know about health warnings and whether they know of ways to minimize their health risk. You can send your information to Save The Bay.
