Free Well Water Tools and Calculators
Practical, test-first tools for people on a private well. Each one runs entirely in your browser: no sign-up, no uploads, and nothing to sell you. Use them alongside a certified lab test, not instead of one.
Any results and directions from these calculators are estimates for planning. Confirm them with a licensed testing facility before you act on them.
Well Water Test Results Checker
Enter your lab results and see which are above EPA health or cosmetic reference levels, sorted by urgency, with unit conversion and plain-English next steps.
Check my results → Bacteria, flooding or well work?Well Shock Chlorination Calculator
How much bleach your well needs, based on casing size, water depth and bleach strength, plus a step checklist, 12-hour hold timer and retest dates.
Calculate bleach → Hard water or scale?Water Softener Size Calculator
Size a softener from hardness, iron and manganese. Compare resin sizes, salt settings, yearly salt use and the sodium softening adds to your water.
Size a softener → No test results yet?Well Water Symptom Finder
Start from what you see, smell or taste. The Finder checks urgent warning signs first, then points you to the right test.
Open the Finder →How these tools work together
Well water problems usually follow the same path: you notice something, you test, you read the results, and then you decide whether and how to treat. The tools follow that path too.
- Notice: the Symptom Finder turns an odor, stain or change into a testing plan.
- Test: the water testing guide helps you choose a certified lab and collect a valid sample.
- Read: the test results checker compares your report with EPA reference levels.
- Act: the shock chlorination calculator handles bacteria, and the softener calculator sizes equipment from your actual hardness and iron.
Our approach
These tools follow the same editorial standards as the rest of the site: reference values come from U.S. EPA and CDC sources, every page lists its sources and review date, and nothing recommends a specific product. The tools are educational and do not replace your certified laboratory, local health department or a licensed well professional. Read our editorial policy and water safety disclaimer.
Privacy
Every tool runs in your browser. What you type is not sent to our server, and there are no accounts. The shock chlorination checklist and timer remember your progress only in your own browser so you can come back to it.
