Private Well Water System Inspection & Aquifer Flow Checklist

A safe private well system requires regular pump and pressure tank inspection, annual water quality testing including coliform bacteria, and ongoing flow rate monitoring.

Well owners sometimes skip annual water testing or ignore gradual changes in flow rate, missing early signs of contamination or aquifer issues that regular monitoring would catch.

Why This Happens

Well water can look, smell, and taste normal even when contaminated with bacteria or nitrates, making regular testing the only reliable way to confirm safety rather than relying on sensory observation alone.

What's Inside

This checklist is interactive, click to check off items in your browser, plus printable if you'd rather keep it for reference, and it covers submersible pump testing, pressure tank drawdown, and coliform testing specific to private well systems, distinct from septic or rainwater harvesting checklists.

Quick Tips

Test for coliform bacteria annually, at minimum.

Address pump short-cycling promptly.

Monitor flow rate over time, not just once.

Frequently Asked Questions

How often should well water be tested for bacteria?

At least annually, coliform bacteria contamination isn't always detectable by taste, smell, or appearance, making regular testing essential for safety.

What causes a well pump to short-cycle?

Often an issue with the pressure tank, like incorrect air pressure or a failing bladder, addressing this promptly protects pump lifespan.

Should nitrate testing be a priority?

Especially if your well is near agricultural areas, nitrate contamination is a specific concern in those regions and worth testing for regularly.

What does declining well flow rate over time indicate?

It can suggest an aquifer or well issue developing, monitoring flow over time rather than just once helps catch this trend early.
