DFW water quality is... complicated. Here's what you need to know.
The short answer: DFW tap water meets all EPA standards but has higher mineral content (hard water) and noticeable chlorine taste/smell in many areas.
By city/area:
- Dallas Water Utilities — sources from multiple reservoirs. Meets all standards. Hard water (moderately hard to hard). Annual report: dallascityhall.com/departments/waterutilities
- Fort Worth Water — Lake Worth and other sources. Similar to Dallas. Report: fortworthtexas.gov/water
- Frisco/McKinney/Allen — North Texas Municipal Water District. Generally good quality. Source: ntmwd.com
- Arlington — Tarrant Regional Water District. Meets standards. Source: trwd.com
Common DFW water issues:
- Hard water (calcium/magnesium) — not harmful but leaves mineral deposits, affects appliances
- Chlorine/chloramine — used for disinfection. Safe but noticeable taste. A carbon filter removes it.
- Lead — most DFW homes built after 1986 are fine. Older homes should test. Free lead test kits from most water utilities.
Should you filter?
- Brita/PUR pitcher: Removes chlorine taste, some contaminants. $20-30 for pitcher + filters. Good enough for most people.
- Reverse osmosis under-sink: Removes everything including minerals. $150-300 installed. Source: Home Depot, Costco.
- Whole-house water softener: If you have hard water issues (dry skin, scale on fixtures). $500-2,000 installed.
Don't buy:
- Bottled water long-term. At $5/case it adds up to $200+/year. A Brita does the same thing.
