a Beginning with CY 2008, annual microbiological sample results will be posted according to the date the sample was collected. Prior to CY 2008, yearly posting of microbiological data results was based upon the sample analysis completion date. For this reason, data from CY 2008 can not be directly compared to CY 2007 and prior years. In addition to the change in date criterion, target sampling that incorporates production volume and results history was introduced as well as incorporating a change in the laboratory testing method.
