What Makes Sherrelwood's Water Unique?
Local geology and source profile
Sherrelwood, an unincorporated community in Adams County, Colorado, receives its drinking water from the Jefferson County Pleasant View Water & Sanitation District (PWSD 8) or nearby metro district utilities serving the Northglenn-Westminster area. The supply is mixed, sourcing from South Platte River diversions via reservoirs including Standley Lake and Ralston Reservoir, supplemented by wells tapping the Denver Basin aquifer system. Treatment occurs at regional plants such as the Robert W. Hite Treatment Facility, employing filtration, disinfection, and fluoridation to meet state and federal standards.
The watershed encompasses the upper South Platte River basin draining the Front Range foothills, with contributions from Ralston Creek and Clear Creek. Water percolates through Denver Basin formations — the Arapahoe Aquifer (Cretaceous gravel and sand) and the overlying Laramie-Fox Hills sandstone — imprinting a moderately mineralised signature from dissolved limestone, dolomite, and evaporite minerals. Paleozoic to Mesozoic limestone and gypsum deposits further leach calcium and magnesium ions, producing the characteristic moderate hardness typical of Colorado's Front Range supplies.
At moderately hard levels, expect soap scum in showers, scale buildup in kettles and dishwashers, and spots on glassware after drying. Hot water heaters and washing machines suffer reduced efficiency from mineral deposits, shortening lifespan by 20–30%. Clean fixtures monthly with vinegar, install low-flow aerators, and consider a water softener for optimal appliance performance and reduced detergent use. Water quality complies with EPA standards per recent Consumer Confidence Reports; pH typically 7.2–8.0, with lead and copper rule met via corrosion control. Notable contaminants include disinfection byproducts and trace arsenic from natural geology, addressed via advanced filtration and chloramination.

Data Sources & Methodology
Water quality data for Sherrelwood is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.
Water Hardness
Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.
pH
Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.
TDS — Total Dissolved Solids
Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.
PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.
Lead
Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.
Appliance Lifespan
Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
