Region 10 AWOP Planning Meeting and Training Event: Tumwater, WA – March 20 – 22, 2012

A Region 10 planning meeting and training event was hosted by the Washington Department of Health AWOP team in March 2012 at the health department’s offices in Tumwater. Participants included AWOP partners from Oregon, Utah, Washington, EPA Region 10, TSC, ASDWA and PAI. The meeting included a training event on turbidity data integrity and turbidity monitoring instrumentation. Representatives from Hach Company attended the training session and presented a chronology on the development of water quality monitoring instruments with a focus on one of the newest online turbidity monitoring instruments that uses a laser as its light source. The training event provided an excellent exchange of information between the instrument vendor and field staff on a wide range of topics from support for out-of-date instruments to fully utilizing the capabilities of the newest instruments (e.g., use of the RSD function).

The planning meeting included updates by the states, region, and NOLT and discussion on priority topics such as planning for the next multi-state CPE in Ilwaco, WA in June, tools and resources for developing training on arsenic treatment and optimization, and approaches for sustaining AWOP in the current funding environment. The next meeting and training event for the group will be a remote conference call and Internet meeting on June 19 – 20, 2012. Technical topics under consideration for the meeting include feedback on the Ilwaco CPE, optimization approaches for arsenic treatment, and draft membrane optimization goals.

Bill Chamberlain (EPA Region 10) and Alvin Smith (Hach Co.) discuss features of a laser turbidimeter and steps to calibrate the instrument.

Ethan Moseng (WA) and Darrell Osterhoudt (ASDWA) discuss ideas on including turbidity data integrity activities into AWOP field events like Performance Based Training.
