Free Printable Well Water Test Log — Bacteria, Nitrates, pH PDF

Private wells need a paper trail

Municipal water sends reports; private wells depend on you. A well water test log keeps bacteria, nitrate, pH, and hardness readings in one place across seasons.

Lab / kit matters because screening strips, certified labs, and county health tests do not carry the same weight. Record the source before you compare numbers year to year.

Use Action / notes for filter changes, shock chlorination, plumbing work, flooding, or nearby construction that could explain a result.

Practical setup tips

Before printing the Well Water Test Log, decide what one row represents and how often the page will be reviewed. That keeps the sheet from becoming a catch-all notes page and makes the finished record easier to compare with similar pages in the same binder or workflow.

• Date should be filled in consistently so the sheet remains useful after the first day of use.
• Bacteria should be filled in consistently so the sheet remains useful after the first day of use.
• Nitrates should be filled in consistently so the sheet remains useful after the first day of use.
• pH should be filled in consistently so the sheet remains useful after the first day of use.
• Hardness should be filled in consistently so the sheet remains useful after the first day of use.
• Lab / kit should be filled in consistently so the sheet remains useful after the first day of use.

If the printable is part of a formal, financial, medical, legal, or compliance workflow, use it as a planning and note-taking aid alongside the official system or professional guidance that applies to your situation.
