North Texas water is safe, well‑regulated, and uniquely… North Texan. Our lakes, long pipelines, big municipal plants, and seasonal taste/odor events give DFW water its own fingerprint. If you've wondered why your tap sometimes smells earthy in winter, why your dishwasher gets spotted, or what "PFAS" means for your family, this guide is for you.
Where DFW's Drinking Water Comes From
Surface Water (Lakes)
- Lake Lewisville, Grapevine, Ray Hubbard
- Seasonal algae and organic matter
- Requires extensive treatment
Groundwater (Wells)
- Trinity and Woodbine aquifers
- Higher mineral content (hardness)
- More consistent year‑round
Seasonal Changes You Might Notice
🍂 Fall/Winter: Earthy Taste & Odor
Lake turnover and algae decomposition can create geosmin and MIB compounds—harmless but noticeable "musty" taste.
🌸 Spring: Higher Chlorine
Treatment plants may increase disinfection to handle runoff and organic matter from spring rains.
☀️ Summer: Hardness Variations
Lower lake levels can concentrate minerals; some utilities blend more groundwater (typically harder).
Common DFW Water Concerns
Hardness (Minerals)
Most DFW water is moderately to very hard (7–15+ grains per gallon). You'll see:
- Scale on fixtures and appliances
- Soap scum and spotting
- Reduced appliance efficiency
Chlorine/Chloramine
Used for disinfection; safe but affects taste:
- Chlorine: easier to remove with carbon
- Chloramine: requires catalytic carbon
- Both can dry skin and hair
PFAS: What DFW Residents Should Know
PFAS ("forever chemicals") are synthetic compounds used in non‑stick cookware, firefighting foam, and industrial processes. EPA is setting new limits starting 2026.
Current status: Most DFW utilities are monitoring and will comply with new federal limits.
Home solutions: Reverse osmosis and activated carbon can reduce many PFAS compounds.
Stay informed: Check your city's annual water quality report for the latest PFAS data.
How to Read Your City's Water Report (Fast)
- Find your CCR (Consumer Confidence Report) on your city's website or EPA's CCR database.
- Scan regulated tables for: DBPs (TTHM/HAA5), nitrate, fluoride, lead/copper, chlorine residual, turbidity.
- Check hardness (often listed as "calcium" or "total hardness")—this affects your appliances and soap performance.
- Look for PFAS data (newer reports may include monitoring results).
Pro tip: Numbers within EPA limits are safe, but you might still want treatment for taste, hardness, or specific concerns like fluoride or TDS.
