2026-03-06 · 6 min read · Guide
Why Well Inspection Matters
A well is a significant investment and liability. Unlike municipal water, the homeowner is fully responsible for water quality, well maintenance, and any contamination issues. A thorough inspection can prevent thousands in unexpected costs.
Physical Well Inspection
Check: well casing condition (no cracks or corrosion), proper sanitary seal at the wellhead, casing extends at least 12 inches above grade, proper grading to divert surface water, no obvious contamination sources within 50 feet.
Water Quality Testing
Request lab testing for: coliform bacteria and E. coli, nitrate, arsenic, lead, radon, pH, hardness, iron, manganese, and PFAS. Some lenders require specific tests. Budget $300-$500 for comprehensive testing.
Well Performance Test
A flow rate test measures gallons per minute (GPM). Minimum recommended: 3-5 GPM for a typical home. Ask about well depth, static water level, and recovery rate. Request the well driller's log if available.
Questions to Ask
When was the well drilled? What is the well depth? Is there a well record on file? When was it last tested? Has any treatment been needed? Is there a water treatment system installed?
