Buying a house with a private well: what to test first

WellWise Finder gives buyers and move-in households a state-aware checklist, clearer lab-path guidance, and plain-English next steps before anyone has to guess what counts as documentation-grade.

PA, NJ, NC, MI, and WI buyers today. Other U.S. ZIPs still get a national fallback with official-source handoff.

What this page optimizes for

Deal-safe first step

Official lab paths are kept visibly separate from retail orientation kits when documentation might affect inspections, lenders, or negotiations.

Calm handoff

The plan comes before installers, affiliates, or any treatment conversation.

Shareable output

You can print, copy, or forward a checklist that keeps the source links and disclaimers attached.

Step 1

Set the property context

Enter the ZIP, pick home purchase or move-in, and note anything unusual such as staining, odor, flooding, or an old test year.

Step 2

Get the initial analyte list

The move-in flow keeps bacteria, nitrate, lead, and arsenic highly visible, then layers state-specific notes where the pilot states support it.

Step 3

Choose the right testing path

Move from the checklist into official directories or vetted mail-in options only after you know which path fits the transaction risk.

Why this converts better

It matches the exact moment of urgency

High intent
  • For buyers: know what to test before the inspection window narrows.
  • For sellers: avoid paying for the wrong kit when official lab documentation matters.
  • For agents and inspectors: share a neutral next-step guide instead of improvising water advice.

Proof of seriousness

Visible boundaries before anyone acts on the result

Use documentation-grade testing rather than a retail screen when the result could affect a transaction or lender review.
