The Toxins You’re Probably Ignoring

1. It’s not perfectly clean

Austin Water (the city utility) reports that the drinking water is treated to meet federal and state standards and that their source water (from the Highland Lakes) is well-protected. Austin Texas+2Austin Texas+2
However — meeting the legal minimum does not mean the water is free of risks or contaminants. As the Environmental Working Group (EWG) cautions: “Legal does not necessarily equal safe.” EWG

2. Disinfection by-products & trihalomethanes

When water is treated with chlorine or chloramine, and organic matter is present, chemical by-products form. Some of these — like trihalomethanes (TTHMs) and haloacetic acids (HAAs) — are on EWG’s list of concern. For example:

• The EWG found that in Austin the total trihalomethanes (TTHMs) measured ~31.4 ppb — that’s over 200 times the EWG “health guideline” of 0.15 ppb. EWG

• Haloacetic acids (HAA9) were found at ~28.3 ppb — over 470 times the EWG health guideline of 0.06 ppb. EWG
  These chemicals are associated with increased risk of cancer and developmental issues in studies. EWG+1

3. Chromium-6 & other heavy metals

Though regulated metals get more attention, there are still unregulated or poorly regulated contaminants. For example:

• Reports show that Austin’s tap water has had chromium-6 (an unregulated carcinogenic form of chromium) averaging around 175 ppt in past data — ~8.75× higher than a level suggested for negligible cancer risk. Hydroviv

• Lead still remains a possibility — while the utility says the system no longer has lead service lines, lead contamination often comes from older home plumbing and fixtures, which the utility can’t always control. Austin Texas+1

4. “Forever chemicals” – PFAS

Per- and polyfluoroalkyl substances (PFAS), aka “forever chemicals”, are a major concern nationwide. These substances accumulate in the body, are linked to cancers, immune dysfunction, hormone disruption, and more.

• The good news: Austin Water’s recent UCMR-5 testing found “little to no detectable traces” of the six most worrisome PFAS in treated water. KUT+1

• The caveat: “Little to no” does not mean zero, and many PFAS chemicals aren’t yet regulated strictly. Also, future assessments and stricter rules are coming. Austin Texas+1
  So yes, this is a place where Austin is doing better than many systems — but “doing better” is not the same as “perfect”.

5. Why this matters for you

• If you’re running a gym, coaching clients, or building a high-performance framework (which I know you are) — water quality matters.

• Dehydration, impaired recovery, subtle inflammatory stresses: these aren’t always about diet alone. If the water you’re drinking is carrying by-products or low-grade contaminants, you’re gaining the hydration, losing part of the benefit.

• For athletes, aging adults, and health-conscious clients, “good enough” water isn’t taking you forward — you want “optimized”.

6. What you can do

• Drink bottled or filtered water that you trust. If you choose bottled, pick one with natural mineral content and no added sugars or extra processing.

• Consider a high-quality home filtration system: look for ones certified to reduce TTHMs, HAAs, heavy metals, and PFAS.

• Stay on top of annual water quality reports: Austin’s 2023 report is public. Austin Texas+1

• When you’re training clients, stress hydration and water quality. Make it part of your coaching narrative: it’s not just how much water, but what kind.

7. The bottom line

Austin’s tap water is not awful, but it’s also not perfect. There are measurable concerns. For a health- and performance-focused person (like you and your clients), letting that slide is leaving gains on the table.

If you truly value peak performance, muscle recovery, clarity, longevity — you don’t want to settle for the minimum. You want the best you can reasonably get. That means upgrading your drink-systems, your gym’s emphasis on quality water, and your personal hydration strategy.
