This is the link to San Francisco's annual water quality report 2017 https://sfwater.org/index.aspx?page=634
The city's major water come from the Tuolumne River, which flows through Central California, from the Sierra Nevada to San Joaquin River. Additionally, the city's water source is supplemented with surface water from the Alameda Watershed and Peninsula Watershed. The report states that the Sierra water is well protected, therefore they are exempt from filtration requirements by the United States Environmental Protection Agency and State Water Resources Control Board Division of Drinking Water. The city's water receives the following treatment to meet all appropriate drinking water standards for consumption: ultraviolet light and chlorine disinfection, pH adjustment for optimum corrosion control, fluoridation for dental health protection, and chloramination for maintaining disinfectant residual and minimizing the formation of disinfection byproducts. These were no detected contaminants high enough for required action. It is said that SF's water is really clean, so my family do not filter our water. However, we always boil our water before we drink it. I do not drink bottled water because the packaging from it produces waste, it does not taste too great, and it is more expensive than the tap water I can get from home. My reasons for not drinking bottled water are the same reasons presented from the Story of Bottled Water video.
Hi,
ReplyDeleteHow does that make you feel? That part of the water you use, the Sierra Nevada water, is not subject to the regulations of the industry? Do you still think it is safe? Dan
Hey Sandy,
ReplyDeleteI was actually thinking the same thing Dan asked you. Part of the water that San Franciscans use is not subject to regulations, so how can one be sure that it meets all the requirements to be safe to drink and use.
