Since 2009, EPA's Office of Ground Water and Drinking Water (OGWDW) has been trying to replace its aging and technologically obsolete SDWIS State system. Originally designed in the mid-1990s and based on a data model going back to the 1980s, the majority of the States, Territories, and EPA Regions use SDWIS State to help manage their drinking water programs. To avoid a fifth incarnation, OGWDW needs to ensure the new system meets today's needs.
