Well water test log template

A well water test log records the date, lab, each parameter, the measured value, the applicable limit, and notes. Keeping every result in one table makes changes easier to spot over time. CDC and EPA advise testing private well water at least once a year.

Why keep a log

A well water test log helps you spot trends, compare new results with earlier ones, and notice when a value changes from one test to the next. It also gives you one place to track when you last tested and what the lab reported.

Template fields

Use simple columns for the date, lab, parameter, value, limit, and notes. If you want a reminder for the next check, pair the log with the well water test schedule and keep your records together with the well water log.

Printable table

A printable table works well because each row can hold one test result and leave room for notes. Add the lab report number, if you have one, and write down anything unusual, such as changes in taste, color, or smell. For testing steps, see how to test well water.

Where limits come from

Use the limit shown by the lab, plus any guidance on EPA and state water quality pages. If you are unsure which limit applies to a parameter, save the source in your notes so you can compare future results against the same reference.

Keep it in the app

Septic & Well can help you keep a well log in one place, along with reminders and records you may want to revisit later. If you are getting started, you can join the waitlist through get the app.

This is not a lab result and not a safety clearance for drinking water. Use a certified laboratory and your state well program.
