Public Water System
Pleasanton’s established city water system uses groundwater from the Carrizo and Queen City aquifers. EWG reports 23 detected contaminants, with 10 above its health guidelines, and notes lead levels exceed California EPA public-health targets by 20 times while EPA-based compliance data indicates the system meets current federal standards. A local estimate places hardness around 10.7 grains per gallon, but conditions can vary by site, so a home water-quality study or free water test is the best way to discover the hardness and contaminants present at your specific property. The City of Pleasanton discourages traditional salt-regenerated water softeners, so treatment choice should be matched to local conditions and household goals.

In Pleasanton, hard water can contribute to scale buildup, spotting, and problems with plumbing and water-using appliances. A traditional water softener is designed to remove calcium and magnesium through ion exchange, helping protect household equipment while improving cleaning performance.
Both water softeners and conditioners address hardness, but they work differently. A salt-based water softener physically removes hardness minerals and exchanges them with sodium ions, while a salt-free conditioner changes how those minerals behave to help control scale without actually removing the minerals from the water.
Jason’s Water Systems combines water softening and advanced filtration in a single whole-house system, giving Pleasanton homeowners one treatment solution for hardness and other water-quality concerns.






Catalytic carbon helps remove chlorine taste and odor along with various other chemicals before water reaches the softening media, giving Pleasanton homes a filtration step before hardness removal.Tested by NSF ANSI 42 up to 400,000 gallons of chlorine removal.

Fine mesh resin removes minerals such as calcium and magnesium through ion exchange, helping reduce the hard-water deposits that can affect dishes, fixtures, plumbing, appliances, hair, and skin.Tested by NSF ANSI 44 up to 25 GPM service flow rat

Crushed garnet media provides the final treatment stage, helping reduce turbidity, cloudiness, and discoloration before water continues throughout the home..It’s never been easier or more affordable to have soft, pure water at home!
