How to submit a sample

  1. 1
    Call or check the website for the right bottles

    Bacteria samples need a sterile bottle from the lab. Chemistry samples usually take a clean container the lab supplies.

  2. 2
    Collect from a cold tap before treatment

    Skip softeners and filters. Remove the aerator, run the water 3 to 5 minutes, then fill without touching the inside of the cap.

  3. 3
    Keep it cold and deliver within 24 hours

    Bacteria samples are time-sensitive. Use a cooler with ice packs and hand it in or ship it the same day.

  4. 4
    Read the report against the standards

    Compare results with EPA drinking water limits. If anything is over, our problem pages explain what it means and how to treat it.
