EPA DMR-QA 39 Study Results: “All Acceptable”

Hydrosphere Research has completed the DMR-QA 39 study with “Acceptable Results” for all test species and all test endpoints. As a lab, we are required to test unknown samples once a year and compare those results to the acceptable analyte ranges for that study. The acceptable range is based on the actual level of analyte in the unknown sample, and on the combined concentration and statistical results from the other participating labs around the country.

As one Hydrosphere Research client put it, “having all acceptable results boosts our confidence in Hydrosphere and cuts down on the time, paperwork, and hassle of having to deal with unacceptable results.”
