Water Quality Testing Oklahoma City
What's really coming out of your tap?
You turned on the faucet and something seemed... off. Maybe the taste changed.
Maybe you noticed stains. Maybe you just bought a house with a well and realized nobody's tested it in
years.
City water or well water — you deserve to know what you're drinking. I collect samples. An
accredited lab analyzes them. You get answers.
I'm Derrick Fredendall. I test water.
I don't sell filtration systems. No conflict. Just data.

What You Need to Know About Your Water
Whether you have city water or a private well, contamination can happen. The difference is who's responsible for testing.
Well Water: You're on Your Own
Private wells are not regulated by the EPA or Oklahoma DEQ. No government agency monitors, tests, or ensures safe water for the 600,000+ Oklahomans on private wells. That responsibility falls entirely on you.
Wells can become contaminated from agricultural runoff, septic systems, old plumbing, flooding, or natural geological conditions. Contamination is often invisible — no taste, no smell, no warning.
City Water: Legal Doesn't Mean Optimal
Oklahoma City water meets EPA standards. But EPA limits are based on cost-benefit analysis, not health optimization. Many contaminants are allowed at levels that health advocates consider too high.
Plus, what comes out of YOUR tap isn't the same as what leaves the treatment plant. Your home's plumbing, age of pipes, and distance from treatment all affect what you actually drink.
What We Test For
Bacteria (Coliform/E.coli)
The #1 priority for well water. Coliform indicates contamination from surface sources. E.coli indicates fecal contamination. Both are health emergencies.
Nitrates/Nitrites
From fertilizers, septic systems, or animal waste. Dangerous for infants (blue baby syndrome). Often elevated in agricultural areas of Oklahoma.
Lead
Leaches from older pipes, fixtures, and solder. Common in homes built before 1986. No safe level for children. Testing at the tap catches what source testing misses.
Hardness (Calcium/Magnesium)
Oklahoma has notoriously hard water. Not a health risk, but damages appliances, leaves scale, and affects soap effectiveness. Testing quantifies the problem.
Iron & Manganese
Cause orange, red, or black staining on fixtures, laundry, and in toilets. Often present in Oklahoma well water. Testing identifies the specific mineral.
PFAS ("Forever Chemicals")
Synthetic chemicals that don't break down. Linked to health issues. Found near military bases, industrial sites, and some municipal water supplies.
EPA Recommendation: Test well water annually for bacteria and nitrates. Test every 3 years for hardness, iron, manganese, and other minerals. Test immediately after flooding, repairs, or if you notice changes.
What You Get With TrueSight Water Testing
Proper sample collection, certified lab analysis, and clear interpretation.
Proper Sample Collection
Samples collected according to lab protocols. Chain of custody maintained. No user error from DIY kits.
Accredited Lab Analysis
Samples analyzed by NELAP-certified laboratory. Results you can trust for real estate, health, or treatment decisions.
Comprehensive Report
Full breakdown of contaminants detected, concentrations, and how they compare to EPA limits and health guidelines.
Interpretation
I explain what the numbers mean in plain English. What's concerning. What's normal. What needs attention.
Treatment Guidance
If treatment is needed, I explain what types of systems address which contaminants. No sales pitch — just information.
Follow-Up Support
Questions after you get results? Call me. I'll walk you through the report and next steps.
How Water Testing Works
Simple process, certified results.
Tell me about your water source (city or well), what concerns you, and what you need the testing for (peace of mind, real estate, health).
I collect samples following strict lab protocols. Multiple points if needed (kitchen, bathroom, outdoor spigot). Proper containers, proper handling.
Samples go to a NELAP-certified laboratory. Results typically in 5-7 business days, faster for bacteria (24-48 hours).
You receive the full lab report plus my interpretation. I explain what each result means and whether action is needed.
If treatment is warranted, I explain your options. If your water is fine, you have documentation proving it. Either way, you know.
Why I Don't Sell Water Treatment Systems
Some companies offer "free" water testing — then sell you a $5,000 filtration system. That's not testing. That's a sales funnel.
When the person testing your water makes money by selling you treatment equipment, their objectivity is gone. Every high result becomes a sales opportunity. Every concern becomes a pitch.
I don't sell filters. I don't install treatment systems. My only job is to test your water and tell you what's in it.
If you need treatment, I'll explain what types of systems address which contaminants. But I don't sell them, so you can trust the recommendation.
- No "free testing" that leads to hard sales
- No incentive to find problems that need expensive solutions
- No commission on treatment equipment
- Just lab data and honest interpretation

Water Testing Situations We See in Oklahoma
The Rural Home Purchase
A Edmond buyer found their dream property — 5 acres with a well. Lender required water testing. Results showed elevated nitrates from the nearby cattle operation. They negotiated a treatment system into the deal.
The New Baby Concern
A Norman couple expecting their first child wanted peace of mind about their city water. Testing showed elevated hardness and chlorine — common, not dangerous, but armed them with data for filtration decisions.
The Rotten Egg Smell
A Moore homeowner's well suddenly developed a sulfur smell. Testing confirmed hydrogen sulfide but ruled out bacterial contamination. Simple aeration treatment solved it for under $300.
The Post-Flood Check
After spring flooding, a Midwest City well owner worried about contamination. Testing detected coliform bacteria. Chlorine shock treatment and re-test confirmed the well was safe again.
