DMR-QA 35 Successfully Completed

Hydrosphere Research recently completed the Discharge Monitoring Report – Quality Assurance (DMR-QA) Study 35 with an acceptable result for all test species and all test endpoints. The DMR-QA 35 is to ensure the integrity of data submitted by the permittee for DMR reporting requirements and evaluate performance of the laboratories to analyze wastewater samples. DMR-QA Study 35 covers major and select minor NPDES permit holders. Participation in the DMR-QA plays a key role in monitoring the quality of data used to assure the integrity of the Clean Water Act’s National Pollutant Discharge Elimination System (NPDES) program. 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 client put it “Having all acceptable results, makes my life easier. We can submit our data and wrap up the study without having to wait on the lab to perform corrective actions and repeat the DMR–QA studies. Knowing that Hydrosphere Research has all acceptable results just confirms that they are the right lab for our toxicity testing.”
