Hardness
Median hardness 47 mg/L as CaCO₃, measured at 4 stations serving this system across 24 results, 2018-05-03 to 2019-07-11. Measured in the water source and distribution area, not at a tap, and not in your home.
What this report cannot tell you
Every figure describes water at a sampling point: a treatment plant, an entry point to the distribution system, or a monitoring station. None of it describes water arriving at your tap. Plumbing between the two can add lead and copper, and if your home was built before 1986 a test kit tells you something no federal dataset can.
