At the beginning of each year, the U.S. EPA notifies NPDES permit holders of their requirement to participate in the annual Discharge Monitoring Report – Quality Assurance (DMR-QA) study under Clean Water Act (CWA) Section 308. If you received a notification letter and have contracted Brooks Rand Labs to perform analyses in support of your permit, please contact us with your verification form information. The deadline to register for the DMR-QA 35 study is March 20, 2015. The study ends July 10, 2015, and results will be available no sooner than August 28, 2015.
