Well water calculator

Check your private well water test results.

Enter the numbers from your lab report. After you calculate, we send you to the iOS app so you can save your result, keep testing history, and set reminders.

What you need

  • Your certified lab report or home screening result.
  • Units exactly as shown on the report.
  • Whether bacteria were reported as present or absent.

For safety and retention, the detailed interpretation opens in the iOS app after you calculate.
