If you're on a private well in North Alabama, you're solely responsible for your water quality. The EPA and ADEM recommend annual testing at minimum — but most well owners test far less frequently, often only when something tastes or smells off. That approach misses the contaminants you can't taste or smell at all.
What to Test For in North Alabama
A basic coliform/nitrate test isn't enough here. Based on regional geology and documented contamination patterns, a complete North Alabama well water panel should include:
- Coliform bacteria & E. coli — annual baseline, required
- Hardness (GPG) — to size a softener correctly
- Iron & manganese — critical in Jackson, DeKalb, Morgan counties
- pH — affects corrosivity and filter performance
- Nitrates — agricultural runoff risk in Limestone, Lawrence, Morgan counties
- PFAS panel — especially within 10 miles of Redstone Arsenal or Decatur industrial corridor
- Arsenic — naturally occurring in North Alabama geology
- Turbidity & TDS — overall water clarity and dissolved solids
Where to Test — Local & Mail-In Options
Auburn University Soil Testing Lab — Basic water panels available at low cost. Contact their analytical lab for current offerings. Good starting point for hardness, pH, and basic chemistry.
Tap Score (simplelabswater.com) — Mail-in, comprehensive panels. Their "Essential Well Water Test" (~$149) covers bacteria, hardness, metals, and nitrates. Add their PFAS panel (~$50 extra) for complete coverage. Results in 5–7 business days with clear plain-English explanation.
National Testing Laboratories (ntllabs.com) — Full PFAS panel available, ~$180. Accredited lab, detailed report. Good for comprehensive testing before major system purchases.
Alabama Department of Public Health (ADPH) — The ADPH Laboratories Division offers certified water testing for a modest fee. Best for official documentation or legal purposes.
Pro tip from 19 years in wastewater: Test in spring (after rains) AND in late summer (during drought). North Alabama wells can shift significantly between seasons — bacteria counts rise after heavy rains when surface water infiltrates, and some contaminants concentrate during drought. One test per year isn't always enough.
How to Take a Well Water Sample Correctly
- Use the sterile bottle provided by the lab — don't substitute
- Sample from a cold water tap closest to the pressure tank — not a filtered tap
- Run the water for 2 minutes before collecting to flush standing water
- Do NOT run the water through a filter, softener, or aerator before sampling
- Keep the sample cold and ship/deliver within 24 hours
