Disinfection Data Integrity Workshop Conducted in Association with the Region 3 AWOP meeting in August

A disinfection data integrity workshop was piloted as part of the August Region 3 Regional planning meeting in Petersburg, West Virginia at their surface water treatment plant.  The workshop was similar to workshops that have been piloted in the State of Iowa for State Regional field staff, and most recently for some plant operators.  A recent sanitary survey report, including a current treatment schematic and a plan view of the baffling in the clearwell storage tank were provided to the workshop participants prior to the site visit.  After introductions, the site visit proceeded with a  plant tour that emphasized the disinfection process and then the group was broken into 4 smaller groups to conduct special studies on the integrity of the disinfection data.  One group conducted studies to verify the online instrumentation used for disinfection monitoring, one group verified the disinfection segments as identified in the CT analysis performed by the state of West Virginia, one group independently performed a CT analysis to compare with the historical state analysis and one group studied the handling of the disinfection data and reporting.  The feedback from the State participants was positive, most said they would try to find a way to integrate aspects of this workshop into their optimization and drinking water oversight programs.
