Why it exists
Finding the right figure for your water is harder than it should be. San Jose Water’s own 2025 report gives hardness separately for each source, from about 5.8 to 16.8 grains per gallon on average, while a sales page can quote a single number for the whole city. This site puts the published figures, the standards and the questions worth asking in one place, so you can read a quote with confidence, and then makes it easy to ask for one.
Where the facts come from
Every figure on this site comes from a public source named on the page: San Jose Water’s 2025 annual water quality report and its softener guidance, the U.S. Geological Survey, the Environmental Protection Agency (including its WaterSense program and its private well pages), the Centers for Disease Control and Prevention, and the NSF/ANSI standards for home water treatment. Where a source has not been read, the site gives no figure and says where to look instead. Rules and reports change; check the source for the latest.
