M5.4 Blog about your Consumer Confidence Reports (CCR) and water quality

  • What is the source of your drinking water?   Where does your water ORIGINATE?  (It is treated at a water treatment plant, but what watershed or aquifer is the sources of the water?)
    • Cal Water System 
  • What chemicals were found in your water that were higher than expected?
    • Fluoride- I understand it is necessary to add fluoride, i guess i never realized how much was really added to drinking water 
  • What chemicals did you NOT expect to find in your water?
    • Microbial contaminants: viruses and bacteria (can come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife) - super shocked about this- had no idea this could be a thing!
  • Where does your water come from? The source! Track it from the source to your tap.
    • South San Francisco system includes 144 miles of pipeline, 12 storage tanks, one collect - ing tank, and 21 booster pumps
  • What did you discover about your water quality?
    • The city of South San Francisco tested over 61,000 samples of water annually! I did not realize they test water so many times a day, but I do appreciate the fact that they are attempting to get rid of contaminants and making sure our water is safe multiple times a day. 
  • Do you use a filter for your water?
    • If a fridge counts, then yes. we consume the water we obtain from a fridge dispenser. 
  • What are you trying to filter out?
    • We know very little about filtering water in my household- i think we obtain our water from the fridge out of habit. 
  • Do you drink bottled water?   How does this square with what you learned when you watched the Story of Bottled Water (see next exercise)?
    • I drink bottled water when i do not have my water canteen with me, however i prefer not to because bottled water creates more waste, and the plastic used to bottle water contains harmful toxins.

    I don't think fridge water is filtered at all.. it may contain different exposures from the plumbing system inside the fridge as well. and OF COURSE there are bacterial and viral contaminants in water THEY ARE EVERYWHERE.

M10.5 Blog about an occupational safety and health organization

OSHA has an alliance with AIHA, in which they developed a training/educational programs for both employers and workers.  What I thought was really cool is that these two organizations joined forces and created "1 page cheat sheets" that both employers and employees can use to identify hazards, methods of control, and other useful resources that are related to occupational safety.  When looking at one of the cheat sheets (Quick tips for job health and safety on safe patient handling and mobility), it appears to be a comprehensive list that prompts the reader to ask themselves questions related to their daily tasks/machinery in which they are using to ensure that not only are they safe, but the people in which they are working with are safe as well. Although cheat sheets may seem a bit juvenile, they could be extremely beneficial for those whose job requires them to be "always on the go."

M11.5 Blog about a Zero Waste Life

When i first started watching the video and saw her little jar of waste I thought to myself "well that is just impossible." As the video went on and she explained the various ways in which people can live a Zero Waste Life it actually seemed pretty doable, it just takes a bit more effort. She made a great point when she talked about how people do not take the time to look at their own waste and what it consists of- I sure do not do it. With that being said, i think i will take a closer look at my trash and figure out what i can eliminate/substitute. For instance, using reusable bags/containers/jars. I use way too many plastic baggies for my snacks when i could and should be using jars and reusable containers. I also need to take composting anf recycling more seriously as i tend to forget that things that are recyclable and reusable can be repurposed. Whether or not I can live a totally Zero Waste Life is questionable, but I can definitely try harder.

M12.9 Blog: Climate Change

What do you personally find most troubling about climate change? I think all things associated with climate change are of huge concern, but after reading the fact sheet I find " Climate change will have the largest health impact on vulnerable populations" to be the most troubling. Low-income and people of color are already at a huge disadvantage in terms of access to healthcare, health education, etc. , so that the fact that vulnerable populations will be even more impacted is very concerning to me, personally.  As a public health professional, what do you think needs the greatest attention right now? What I believe needs the greatest attention is education pertaining to climate change. Majority of the population/world knows very little about climate change and the impact it has on overall health. I think if more educational opportunities were provided to the greater population, more individuals would understand the dangers associated with climate change ...
