About this database
Water hardness and mineral data comes from laboratory analysis of real water samples. Coverage includes 1,200+ US cities with verified PPM values sourced from utility Consumer Confidence Reports and EPA water quality databases.
Results reflect municipal tap water delivered to residential addresses. Private wells, whole-house water softeners, and reverse osmosis systems will modify your actual tap water hardness levels.
