Nobody's tracking your well. Your lab already sent you the numbers.
23M U.S. households drink from a private well. EPA's public database and EWG's Tap Water Database only cover water utilities, by law. Upload the PDF your lab sent you and get every reading checked against the same EPA levels a utility has to meet.
No account, no AI model reading your file. Extraction runs in your browser, and only the matched numbers reach our server.
Private well pump
Tap Score reads its own kit. We read yours.
Most well owners already have results, from a county health program, a mortgage closing, or a lab they picked themselves. They just have a PDF full of codes nobody explained.
Not in SDWIS
EPA's Safe Drinking Water Information System covers public utilities. A private well has no federal record. The lab report in your inbox is the only one that exists.
The same table a utility answers to
Your numbers get checked against EPA Maximum Contaminant Levels, Lead and Copper Rule action levels, and EPA Secondary Standards. Published thresholds, not a guess about what's normal.
Use what you have
Already tested through a county program or your own lab? Upload that PDF. You don't need a second kit to find out what the first one means.
Nitrate follows land use, not state lines
No AI reads your results
Your file never leaves your device, and every number gets checked against EPA's own published levels, not a model's best guess.
Nothing uploaded
Your report is read in your browser. Only the matched readings, the numbers themselves, ever reach our server.
No AI involved
No model reads or interprets your results. Each line is matched to a known contaminant and compared to a fixed number, the same way every time.
EPA's own levels
Each match is checked against a published EPA threshold: under, close, or over. Free and complete on screen. A downloadable copy is $12.
Risk follows bedrock, not borders
Arsenic and radon come from local rock. Nitrate follows farmland. See what USGS research flags for your state.
19 parameters, published limits
The tests that actually show up on a private-well lab report: health limits and the taste/odor standards next to them.
