What Makes Berkley's Water Unique?
Local geology and source profile
Berkley, Colorado, in Adams County — an Adams County neighborhood in the Denver suburb adjacent to Westminster and Arvada in the north Denver metro area — receives its water from Denver Water or North Table Mountain Water District, drawing from Dillon Reservoir and South Platte watershed through the north-central Colorado distribution.
The soft 81.5 mg/L hardness and TDS of 147.7 mg/L reflect the Adams County Denver Water supply's soft Front Range character — the Precambrian Front Range Granite is highly insoluble, while Cretaceous Pierre Shale contributes modest calcareous mineral content from its slightly calcareous mudstone and shale (compare Westminster CO: 79/142 in Adams County comparable; Arvada CO: 83/153 in Jefferson County comparable; Berkley consistent soft from the same Adams County Dillon Reservoir South Platte Front Range granitic supply). The South Platte watershed at Adams County — Precambrian Front Range Granite (insoluble — primary dilutant), Cretaceous Pierre Shale (slightly calcareous — primary hardness contributor), and Quaternary South Platte alluvium (slightly calcareous — minor TDS).
At 81.5 mg/L with TDS 148, Berkley's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 3.0 ppt is low — a clean result for the north Denver area. Review Denver Water's annual water quality report.
Geology & Source: Berkley in Adams County draws from the Denver Water on Dillon Reservoir blend (Adams County, north-central Colorado) — the South Platte watershed at Adams County drains Precambrian Front Range Granite (insoluble) and Cretaceous Pierre Shale (slightly calcareous) — Colorado Adams County Dillon Reservoir South Platte Front Range granitic supply produces soft water at 81.5 mg/L with TDS 147.7 mg/L.
