This is needed to determine whether new potential sources of contamination may be introduced in the future and to identify future actions for addressing these anticipated sources. Land- and water- use changes may introduce new contamination sources or result in changes to groundwater use and quality. The anticipated changes may occur within the jurisdictional authority of the ERMU although some may not. The following table describes the anticipated changes to the physical environment, land use, and surface water or groundwater in relationship to their 1) the influence that existing governmental land and water programs and regulations may have on the anticipated change, and 2) the administrative, technical, and financial considerations of the public water supplier and property owners within the DWSMA. 6
