Wellhead Protection Inspection Logger
Drinking-water well site inspection — sanitary seal, casing, vent, grading, setbacks and contamination sources nearby; offline + GPS.
New well site inspection
Sanitary surveys by regulators run every 3–5 years; operators should walk each wellhead monthly and after floods.
Field guide: Wellhead Protection Inspection Logger
Groundwater contamination almost never comes up the aquifer — it goes down the well: a cracked sanitary seal, an unscreened vent, a flooded wellhead, or that abandoned well fifty meters away nobody sealed, acting as a direct pipe from surface to aquifer. The classic sanitary-survey findings are all surface-visible, which is why a monthly operator walk with this checklist catches what a 5-year regulatory survey will otherwise write up.
The contamination-sources panel makes the walk a miniature wellhead-protection assessment: septic systems, fuel storage, livestock and pesticide handling inside setback distances are findings even when the wellhead itself is perfect. Pit and vault wells get flagged as legacy defects — a wellhead below grade in a floodable pit is a sanitary defect by construction, on every modern code.
Field tips
- After any flood event that reached the pad, treat the well as suspect: log it, sample it, and disinfect per procedure before relying on it.
- Check the vent screen with a fingertip, not a glance — wasps and mud daubers defeat visual inspection.
- Map every abandoned well you learn about within the protection zone; unsealed ones are the area's biggest aquifer threat and someone else's cost until documented.

Frequently asked questions
What does a sanitary seal actually do?+
It closes the top of the casing around every penetration (pump wiring, airlines) so nothing enters the well bore from the surface. Cracked rubber, missing bolts, or improvised cable holes defeat it. Same for the annular seal — the grout between casing and borehole — whose failure shows as settlement or gaps at the pad.
What setbacks apply around a drinking-water well?+
Jurisdiction-specific, but typical minimums run 15–30 m from septic tanks and leach fields, more from manure storage and chemical handling. Sanitary surveys check these; so should the operator's walk, because land use changes between surveys — a new fuel tank near the well is a finding the regulator hasn't seen yet.
Why are abandoned wells such a threat?+
An unsealed abandoned well bypasses every protective layer of soil and connects the surface (or a shallow contaminated zone) straight to the aquifer your well shares. Most states require licensed decommissioning (grouting full depth). Logging their locations with GPS is step one of getting them sealed.
How high should the casing stand above grade?+
Modern standards typically require 300 mm (12 in) minimum above finished grade — more in floodplains, often above the 100-year flood level. Casings cut low for mowing convenience, or buried by re-landscaping, are common and serious findings: surface water at the casing top is the textbook contamination event.
