What Should I Test My Water For in Houston?

When Houston homeowners call us for a free water test, one of the first questions they ask is: “What exactly should I be testing my water for anyway?”

Not every contaminant is obvious. Some you can taste or smell, but many are invisible. Here’s a breakdown of the most important things to test for in Houston’s tap or well water.

Common Contaminants in Houston Water

1. Hardness (Calcium & Magnesium)

• Houston has some of the hardest water in Texas.

• Causes scale buildup in pipes and appliances, dry skin and hair, and soap inefficiency.

2. Chlorine & Chloramines

• Added by the city to disinfect water.

• Leave an unpleasant taste and smell, and causes skin irritation.

3. Iron & Manganese

• More common in well water.

• Cause orange staining, metallic taste, and laundry discoloration.

4. pH Balance

• Low or high pH can corrode plumbing and fixtures.

5. Heavy Metals (Lead, Copper)

• Usually from old pipes or plumbing, not the water source itself.

• Harmful even in trace amounts, especially for children.

6. Nitrates & Nitrites

• Often from agricultural runoff.

• Dangerous to infants and pregnant women.

7. PFAS (“Forever Chemicals”)

• Found in industrial runoff and firefighting foam.

• Linked to hormone disruption, immune issues, and cancer risks.

8. Bacteria

• Some wells are vulnerable to bacterial contamination.

• Causes health risks if not addressed.

Why These Tests Matter

Without testing, you’re left guessing—and the wrong water treatment system can be a costly mistake. Testing ensures you get:

• Accurate results about what’s in your water

• Customized solutions instead of one-size-fits-all equipment

• Long-term protection for your home, appliances, and health
