On August 10th, EPA held a nationwide webinar on the lead and copper rule revisions (LCRR). Included was the data schema that should be followed. ESRI's solution looks close but is not the same. While the EPA does NOT require the exact schema be used, I think it would be a very good idea to. Please consider matching the EPA data schema in the solution. The schema presented is attached to this idea, or can be found on EPA's Lead and Copper page including a recording of the August 10th presentation. In the spreadsheet, the schema is on tab "Detailed Inventory". Since this is mandatory for every water provider with reporting deadlines, time is of the essence. Thanks.
