The EPA has revised the use of scheduled WP studies meeting DMRQA 30 reporting requirements.  Beginning in 2010 all regularly scheduled WP studies between the dates of January 1, 2010 and July 2, 2010 may be used to meet DMRQA 30 testing requirements.

To use a WP study for your DMRQA 30 reporting requirements, RTC must have your NPDES permit# prior to the close of that WP study.  RTC offers 3 regularly scheduled WP studies, WP10-1, WP10-2, and WP10-3A, which may be used for DMRQA 30 reporting.  RTC’s WP10-1 study starts January 20th and is open for 45 days.  

Please contact an RTC Proficiency Testing Coordinator, PT@RT-Corp.com or 1-800-576-5690, if you have questions regarding using a WP study to meet your DMRQA 30 reporting requirements.
