Well Water Testing: What to Test For, How Often, and What the Results Mean
The EPA does not regulate private wells. The annual baseline to test for, what to add every three to five years, and what the results point to.
How to choose
Quick answer
The EPA does not regulate private wells — testing is the owner's responsibility, and most of what matters gives no warning by taste, smell or appearance. The annual baseline is total coliform, nitrates, pH and total dissolved solids, with a broader panel every three to five years. Everything downstream follows from that result: the test selects the treatment category, not the other way around. Pump and pressure-tank symptoms are a separate diagnosis from water chemistry, though sediment and mineral buildup can connect the two.
What to compare
- Certified lab versus home kit. Kits are fine for a spot check on pH and hardness; bacteria, lead, arsenic and trace metals need a lab.
- Local geology. Shale wells commonly show iron and sulfur, limestone raises hardness and arsenic, agricultural areas see nitrates and seasonal coliform.
- Multiple problems at once. Bacteria plus iron plus sulfur is a common combination, which is why a system designed around one test result outperforms single-issue gadgets bought one at a time.
