Culligan of Santa Clara, CA

Much of the South Bay has hard water, although hardness levels vary depending on the water source. San Jose Water reports hardness levels of 11 to 26 grains per gallon for groundwater, 4 to 9 grains per gallon for imported surface water, and 5 to 12 grains per gallon for local mountain surface water. The utility classifies water as hard when it exceeds 7 grains per gallon. Because water utilities blend different sources, hardness can change between neighborhoods and throughout the year. San Francisco and parts of the Peninsula receive much softer water from the Hetch Hetchy system. A free in-home water test from Culligan of Santa Clara can measure the hardness of your tap water.

San Jose Water reports that its drinking water meets or exceeds all state and federal drinking water standards. Other utilities throughout the South Bay and Peninsula publish their own annual Consumer Confidence Reports outlining local water quality. However, many homeowners choose additional water treatment to address specific concerns. PFAS and total dissolved solids (TDS) are among the common water quality concerns reported to Culligan of Santa Clara, while older household plumbing may also contribute lead to drinking water. A free water test from Culligan of Santa Clara can help identify common water quality concerns at your tap.

Fluoride practices vary by water utility, so the answer depends on your water provider. Your utility's annual Water Quality Report, also known as a Consumer Confidence Report, identifies whether fluoride is added and at what concentration. Homes that rely on private wells may contain naturally occurring fluoride. Some drinking water filtration systems can reduce fluoride, but performance varies by model. Ask your Culligan of Santa Clara water expert for specific performance information about any system you're considering.

A Culligan water softener removes hardness minerals before water reaches your fixtures, helping reduce new water spots and scale buildup.
