Water provided to most of the San Francisco residents (San Francisco Regional Water System), comes from spring snowmelt flowing down river which ends up in the Hatch Hetchy Reservoir. The main chemicals found in the water are Chlorate, which can cause harm to the Thyroid, Radiological Contaminants and Total Trihalomethane's, both of which can cause cancer. There are other naturally occurring contaminates in the water as well. I was not expecting to see radiological contaminants in the water. The overall water quality is actually very good and well within governmental standards. At home, we do use a water filter in the refrigerator. I would say that in using the water filter, we would hope to filter out any bad contaminates in the water that could accidentally be there. It just feels safer to use the filter. I do use water bottles, but mainly for convenience. I know that it is bad for the environment, and I have recently purchased a refillable bottle that I carry around me to reduce plastic usage. There are certain circumstances in which I use bottled water and it stems from a distrust of the tap water. I do not feel comfortable drinking tap water from certain locations that I am not familiar with. This could be in a hotel, rural areas, or areas outside of the country.
In San Francisco, there are 3 sewage treatment facilities. There is the North Point Wet Weather Facility located at Bay Street and the Embarcadero. It was built in 1951 and it is important to note that this facility is only active during wet weather, which I find is very interesting since it barley rains in SF. There is also the Oceanside Treatment Plant which was built in 1993. it receives about 20% of the cities flows. The last one is the Southeast Treatment Plant. It was built in 1952 and treats the other 80% of the cities flows. Needless to say, the Southeast Treatment Plant is much larger than the others and does the bulk of the cities wage work for SF residents.
Hi Jordan,
ReplyDeleteI feel safer using a filter too, even though the tap water in San Francisco tastes great, you just can never be too sure! I am mostly scared about the pipes because the house I lived in was so old.
Hi Jordan,
ReplyDeleteI also use a filter at home and take my reusable water bottle places, but it is a bit uncertain using water from the tap especially in new places. Maybe if they had some sort of rating or city labeling of the safety of the tap, more people would be comfortable drinking it.
