What is the hardness of the City's new groundwater source?

Prior to making the transition to groundwater wells, the treated surface water from the Cowlitz River was historically “soft”, with a hardness level of approximately 27 milligrams per liter. Groundwater hardness from the Mint Farm aquifer varies slightly among each of the four production wells, ranging from 69 to 91 milligrams per liter. Although the difference in hardness is a change from what our customers are accustomed to, the City of Longview groundwater is similar in hardness to other local water systems.
