West Virginia American Water delivers water to Charleston from surface (lake/reservoir) at 185 mg/L (CaCO₃). That is very hard for a US municipal supply. On Charleston glass that residency means visible spotting on dark glazing within a single dry-down cycle and accelerated lower-sash mineral residue over the working year. The local operating practice is a citric pre-treatment followed by a citric finish-rinse on long-residence glass, and a deionized rinse on heritage and high-value stock where chemistry matters most.
