What Makes Stallings's Water Unique?
Local geology and source profile
Union County Water supplies the town of Stallings, North Carolina, drawing primarily from the Catawba River watershed. This includes water from lakes and reservoirs within the Catawba system, which are then treated at Union County facilities before distribution. Groundwater sources also supplement the supply. Stallings is located in Union County, southeast of Charlotte, and is part of the Upper Pee Dee River Basin. Annual Consumer Confidence Reports are published by Union County Water, detailing the system's adherence to state and federal drinking water standards.
The region's water originates from the Carolina Piedmont physiographic province. The underlying geology features ancient metamorphic rocks, such as gneiss and schist from the Precambrian Grenville Province, alongside granitic intrusions dating back to the Paleozoic era. Groundwater is often sourced from shallow aquifers within this fractured bedrock. The presence of carbonate minerals and the weathering of mafic components within these rock formations contribute significantly to the water's hardness. Prolonged contact with mineral-rich soils and rock also increases dissolved solids.
As a consequence of its hardness, Stallings' water can lead to scale buildup in pipes, water heaters, dishwashers, and washing machines, which reduces their efficiency and shortens their lifespan. You'll likely notice reduced soap lathering, requiring more detergent for cleaning and potentially leaving laundry stiff. Homeowners might consider regular descaling of fixtures and flushing hot water tanks. Installing a water softener is often recommended to protect appliances, improve cleaning performance, and prevent issues like spotty dishes or dry skin and hair. The water meets all EPA health standards and is safe to drink.
Geology & Source: Piedmont metamorphic and igneous rocks; gneiss, schist, granite; carbonate minerals and weathering impart hardness

Data Sources & Methodology
Water quality data for Stallings 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.
