In May 2012, EPA's National Homeland Security Research Center (NHSRC) released Need to Know: Anticipating the Public's Questions during a Water Emergency. The report provides the results of interviews with utility managers, communications staff and focus groups of members of the public. Utility staff interviewed for this project were from the City of Chicago, San Diego Public Utilities, Charlotte-Mecklenburg Utility Department and the Massachusetts Water Resources Authority. The conclusions can help utilities develop a public engagement strategy in advance of a water emergency. WaterISAC and AMWA assisted NHSRC with the study and the published report.
