Independent measurement

Test my tap

A utility report describes the water system. A home test describes water at the actual sample location. Both are useful; they answer different questions.

Choose a test for the question you have.

Sampling method, analyte list, laboratory certification and reporting limits matter. H2Optic will show these details before recommending a test.

Find a certified laboratory

You never need to purchase through an H2Optic partner. Use your state’s certified laboratory directory or contact the state drinking-water program.

How to evaluate a lab

Affiliate disclosure: H2Optic may earn a commission when you purchase testing through certain links. This does not change the price you pay or how H2Optic interprets water-quality information. Testing providers do not determine H2Optic’s conclusions. How H2Optic is funded.

Before you sample

Protocol is part of the result.

First-draw and flushed samples can answer different questions. Record the fixture, date, time, filtration status, stagnation period and any instructions supplied by the lab.

Do not change a laboratory’s protocol unless the lab or relevant authority instructs you to do so.
