Well Water Log

The EPA recommends testing your well every year. Log your lab results, see what they mean in plain English, and never miss another test.

13 million U.S. households drink from a private well, and no agency tests that water for them. The EPA recommends testing every year, but lab reports come back as a wall of numbers and a filing cabinet is where they go to die.

WELL WATER LOG is the well owner's testing companion:

UNDERSTAND YOUR RESULTS Enter your lab results and every parameter is checked against EPA drinking water standards and explained in plain English, not chemistry jargon. Bacteria, nitrate, arsenic, lead, uranium, radon, iron, hardness, pH, and more: 18 parameters covering the standard analysis state health departments recommend.

NEVER MISS A TEST Annual reminders based on your actual last test date. Get nudged when it's time, order a mail-in kit, log the results when they arrive.

SEE THE TREND BEFORE IT'S A PROBLEM (Pro) Charts show every parameter over the years, with EPA limits drawn on the chart. Rising chloride or creeping nitrate is visible years before it becomes an emergency.

SCAN, DON'T TYPE (Pro) Photograph the lab report and the values fill themselves in.
