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


Our area focused is: Daly City, California

Our water comes from the Hetch Hetchy Watershed, responsible for providing over 80% of the Bay Area's water supply. As a reservoir, the primary source of the system is filled by snow melting, runoff water and the Tuolumne River. Water in the Hetch Hetchy Reservoir is treated but not filtered because of the large quantity. 

I discovered a lot about our water quality, particularly focusing on what was in our water - Arsenic was low, Chromium was low, and traces of Cryptosporidium and Giardia were never found in the wells of Daly City. That was comforting because my friend just came back from camping and he has an idea that he may have caught Giardia from drinking not filtered water.

At home, my husband and I do not filter our water, but we boil it or drink pre-bottled filtered water at our leisure. We do have a Brita filter for our dog to drink water from because it refrains from mixing with her saliva and causing red tear ducts to mix in her eyes. This has drastically changed the physical appearance of our dog, which we get lots of questions why our dog doesn't have red teared- eye gaps and a 'brassy/ copper' mouth. We are trying to filter out the natural minerals that mix with our dogs saliva that causes their fur to turn colors due to oxidation. 

We do drink bottled water, but I prefer drinking boiled or even tap water, over my husband who grew up on always boiling his water, no matter how 'pure' the water had come from. 

Prior to watching the video on bottled water, my husband (as previously mentioned) noted he rarely drinks tap water - he is adamant about drinking water at a 'clean' source. Now knowing not all bottled water is cleaner or healthier for you, we can make a clear point that there is no difference the two.

  1. That is so crazy about the changes you saw in your dog after giving her only filtered water. If there are visible changes in her appearance it makes you wonder what might change if we were all to drink only filtered water.

  2. Wow, I had no idea filtered water was so drastically different. I would somehow like to test the variability of taste, and content in both my tap water and filtered water.
    Some cultures like hot water. I love hot water honey and lemon. But now that I think about it, the honey and the lemon could have potential pesticides or chemicals from their own manufacturing.
