Your definitive guide to DFW water quality. Real research, honest testing, and professional installs — written by licensed Texas water specialists.

Key Takeaways:

  • Annual Safety Test: Test for Total Coliform & E. coli bacteria every year. This is non-negotiable for health.
  • The "Big Three" Nuisances: Test for Iron, Manganese, and Hydrogen Sulfide (Sulfur). These cause stains and smells.
  • The Invisible Risks: In rural areas, test for Nitrates (from fertilizer/livestock) and Arsenic (natural deposits).
  • Basic Chemistry: Know your pH and Hardness to protect your plumbing from corrosion or scale.

If you rely on a private well in North Texas, you are the utilities manager for your home. There is no city worker checking your water safety; it is entirely up to you.

The "Must-Haves" (Health & Safety)

  • Total Coliform & E. Coli: This is the most critical test. It indicates if surface water (and potential sewage or animal waste) is entering your well. If this is positive, your water is not safe to drink until treated (shock chlorination or UV disinfection).
  • Nitrates: Common in agricultural areas like Celina, Prosper, and rural counties. High nitrates are dangerous for infants ("blue baby syndrome").

The "Aesthetics" (Stains & Smell)

  • Iron: Causes red/orange stains.
  • Manganese: Causes black stains.
  • Hydrogen Sulfide: The "rotten egg" smell.
  • Total Dissolved Solids (TDS): A general measure of overall water quality.
