Become a Certified Well & Water Sampling Inspector

This comprehensive online program teaches you how to perform professional well system evaluations from the source to the tap. You'll learn how to analyze functional flow rates, evaluate pressure delivery systems, identify structural and sanitary defects, and safely navigate complex local water sampling and laboratory transport protocols with accuracy and confidence.

Why Inspectors Add Well Evaluation Services

  • High-Margin Ancillary Income - A typical well evaluation and water draw takes minimal additional time on-site but routinely generates an additional $150 to $300+ per inspection, plus laboratory margins.
  • Critical Liability Protection - Subterranean equipment failures and contaminated aquifers are incredibly expensive to remediate. This course teaches you to inspect within the framework of the AHI WellSOP, protecting your clients, safeguarding your business from liability, and keeping you indispensable to agents.
  • Advanced Defect Identification - Build expert-level knowledge in recognizing short-cycling pumps, water-logged pressure tanks, damaged well caps, surface runoff intrusion, and compromised sanitary seals.
  • Clear, Visual Deliverables - Learn to produce institutional-grade documentation and analytical reports that leave no room for interpretation during real estate negotiations.
  • Equipment Mastery - Gain the confidence to select, maintain, and deploy the right flow meters, pressure gauges, water testing kits, and sterile sample collection hardware.

Real Results From Inspectors
"Adding well testing was a no-brainer. Now, two out of every three clients buying a rural property ask me to check their well water while I'm already out there. It doesn't take much extra time, but it really pads the paycheck on those jobs. Plus, the buyers appreciate knowing their drinking water is safe before they sign on the dotted line." — Jim B., Certified Well Water Inspector
