What Makes Bridgeton's Water Unique?
Local geology and source profile
Bridgeton, Missouri, in Saint Louis County — a Saint Louis County city adjacent to Maryland Heights and Hazelwood near Lambert-St. Louis International Airport in east-central Missouri — receives its water from Missouri American Water, drawing from the Missouri River through the east-central Missouri metropolitan distribution.
The soft 99.5 mg/L hardness and low TDS of 160.4 mg/L are notably soft for Saint Louis County — the Missouri River at St. Louis draws heavily from upstream Rocky Mountain and Great Plains runoff that is diluted by the Precambrian insoluble gneiss of the Missouri headwaters, producing softer water than the Meramec River draws (compare Maryland Heights MO: 97/156 in Saint Louis County comparable; Hazelwood MO: 102/164 in Saint Louis County comparable; Bridgeton consistent soft from the same Saint Louis County Missouri River Rocky Mountain supply). The Missouri River at Saint Louis County — Precambrian Rocky Mountain gneiss (insoluble — primary dilutant), Cretaceous Great Plains shale (slightly calcareous — primary hardness contributor), and Quaternary Missouri alluvium (calcareous — TDS contributor).
At 99.5 mg/L with TDS 160, Bridgeton's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 3.7 ppt is moderate and well-managed. Review Missouri American Water's annual water quality report for the latest contaminant data.
