What Makes Cabot's Water Unique?

Local geology and source profile

Cabot Waterworks is the primary water utility serving Cabot, Arkansas, and surrounding areas in Lonoke County, providing drinking water to approximately 26,770 people. The utility is reachable at 501-843-4654 with a 24/7 emergency line, and maintains a mailing address at PO Box 1287, Cabot, AR 72023. Annual Consumer Confidence Reports (CCRs) detailing water quality are available at cabotwaterworks.com. Treatment involves disinfectants including chlorine, chlorine dioxide, and hypochlorite; no specific treatment plant names were identified in available reports.

Cabot's water supply draws from the Arkansas River and supplementary wells tapping the Quaternary alluvial aquifer of the Arkansas River floodplain. The river drains Permian evaporite terrain and Cretaceous carbonate formations across central Arkansas, while alluvial sediments with calcareous horizons add further mineral load. Dissolution of carbonate-bearing rock and evaporite minerals along the river's course produces a hard water character with elevated calcium, magnesium, and total dissolved solids typical of the region.

Hard water from Cabot's supply leads to scale buildup in water heaters, dishwashers, and washing machines, reducing efficiency and lifespan over time. Regular vinegar descaling and periodic appliance flushing are recommended maintenance steps; a water softener can help mitigate these effects and extend equipment life. Cabot Waterworks has reported 3 contaminants above EPA health-based MCLGs in at least one served area — review the latest CCR at cabotwaterworks.com/ccr1 for specifics. Treatment includes disinfection with chlorine, chlorine dioxide, and hypochlorite; annual CCRs confirm compliance reporting.

Frequently Asked Questions

Is Cabot's water safe to drink?
Yes. Cabot's water meets all federal safety standards. The hardness is ≈ 0–59 mg/L (Soft), which is safe to drink. High hardness affects appliances and taste, but poses no health risk.
Do I need a water softener in Cabot?
Cabot's water is soft at ≈ 0–59 mg/L. A water softener is generally not necessary, though a carbon filter can improve taste and remove any remaining chlorine.
How does Cabot compare to the USA average?
The USA national average is 151 mg/L. Cabot (≈ 0–59 mg/L) is 121 mg/L below the national average. The softest major city is Scarsdale at just 0.02 mg/L.

Data Sources & Methodology

Water quality data for Cabot is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.

Estimated

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.

Estimated

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.

Estimated

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.

Measured

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.

Modelled

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.

Calculated

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.
