What Makes Magna's Water Unique?
Local geology and source profile
Magna Water District, located at 8885 West 3500 South in Magna, Utah (Salt Lake County), serves the Magna metro township and surrounding areas. The utility operates under the Safe Drinking Water Act and publishes annual Consumer Confidence Reports. Water supply is drawn from both groundwater and surface sources within the Jordan Valley aquifer system and local surface water resources in the Wasatch Front region. Residents can contact the district at (801) 250-2118 or visit magnawaterut.gov.
The Magna service area lies within the Jordan Valley watershed, underlain by Quaternary alluvial deposits and deeper Tertiary-age sedimentary formations containing limestone and dolomite. These mineral-rich rock layers naturally contribute dissolved calcium and magnesium to the groundwater. Utah's arid climate increases reliance on groundwater sources, which typically contain higher mineral concentrations than surface water; the presence of limestone formations shapes the moderately hard character of the supply.
At moderately hard levels, Magna's water causes some scale buildup in kettles, coffee makers, and water heaters over time, though the impact is less severe than in very hard water areas. Residents may notice soap residue on dishes and skin, and appliance efficiency may gradually decline. A water softener is recommended for those concerned about scale accumulation and appliance longevity, though treatment is not essential for health or safety. The Magna Water District's 2024 Consumer Confidence Report confirms the supply meets all Safe Drinking Water Act standards, with monitoring for lead, copper, and other regulated contaminants.
Geology & Source: Wasatch Front Jordan Valley aquifer; Quaternary alluvial deposits over Tertiary limestone and dolomite — mineral-rich formations dissolve calcium and magnesium, yielding moderately hard supply

Data Sources & Methodology
Water quality data for Magna 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.
