M5.7: Your Sewage Facilities

-
San Francisco has three sewage facilities:

  • North Point Wet-Weather Facility: built in 1951, active only during wet weather, provides pretreatment and primary treatment with disinfection of wastewater from the northeast part of the City. Capacity is up to 150 MGD (million gallons per day). This system is outdated, with new improvements to infrastructure to come soon.
  • Oceanside Treatment Plant: built in 1993, receives up to 20% of the City's flow, treats water from the westside of the City. Capacity is up to 15 MGD, but during a rain stop, it can be up to 175 MGD. 
  • Southeast Treatment Plant: built in 1953, receives up to 80% of the City's flow, our largest wastewater facility. Responsible for the Bayside, Daly City, and Brisbane. Capacity is 60 MGD and up to 250 MGD during a rainstorm.  
These facilities combined serve over 800,000 customers and is operated by the San Francisco Public Utilities Commission (SFPUC). The facilities collect and treat both sewage and stormwater and discharge that water into the San Francisco Bay or Pacific Ocean.

    Its crazy to see that two of the three water facilities were built in the 50's. It makes you wonder what improvements have been made to the facilities since then and how water in the facilities has been treated throughout its existence.

    I think that if they were built that long ago then they probably have failing infrastructures, which I believe is one of CA's main problems with water. They also have PVC pipes, which were banned in Europe due to their adverse health effects and chemicals leeching into the drinking water.

Answer the following questions: What is the source of your drinking water?  According to SF Water, San Francisco gets 85% of our water from the Hetch Hetchy watershed. The rest of our water comes from the Alameda and Peninsula watersheds. In April 2017, SF also started using groundwater from the Westside Groundwater Basin aquifer. Where does your water ORIGINATE? (It is treated at a water treatment plant, but what watershed or aquifer is the sources of the water?)  The Hetch Hetchy watershed. What chemicals were found in your water that were higher than expected?  Most of the chemicals listed were well under the maximum contaminant level goal or the maximum contaminant level. However, I was surprised to know that byproducts of disinfection were still found in the water, like haloacetic acids. I also saw that even though the range for Giardia lamblia was <0-0.11, I thought it was a bit scary because it was still detected. What chemicals did you NOT expect to ...

Environmental Health News, Week 13: Diesel Ban in Europe

-
There is a small environmental organization, called Deutsche Umwelt Hilfe (DUH) or Environmental Action Germany, that is advocating for reducing air pollution in the European Union. In February, the German Federal Administrative Court banned older diesel fueled cars in certain cities and areas in Germany. This is a big step for the EU as diesel powered cars are used more than gasoline cars. According to the article, diesel cars are a major contributor to air pollution: 60% of nitrogen dioxide in Germany comes from motor vehicles, with three-quarters of that from diesel. Nitrogen dioxide levels and particulate matter levels are almost double the EU limits in cities like Munich. This pollution creates carcinogens and is associated with premature deaths, cardio-pulmonary diseases. Some say that this is the beginning of the end of diesel in the EU. "Paris, Copenhagen, London, and Madrid had already announced they are considering bans on some diesel cars beginning in 2020. " Whi...

M6.4: Industrial Farming

The Vanishing of the Bees and Dirt!: The Movie Before watching "The Vanishing of the Bees", I had only heard about this issue. I never thought to look deeper into it, but after watching this film, I see that it is an extreme issue that is directly related to our actions. "Dirt!: The Movie" further reveals that as a species, we are causing extensive harm to the planet and the environment. One thing that stood out to me was the use of pesticides. Pesticides harm our bees, and other pollinators, but they also harm the earth. As we continue to use these harmful chemicals, we kill our pollinators, destroy our soil, and ruin our environment. Big agriculture seeks to create monoculture and sustain human demand, but in reality, none of this is sustainable at all. From the dirt, to the bees, to the water, to us, we need to think of ways to preserve the environment and work with it to improve for the future. Factory Farms  According to the map, there are no factory farm...
