This is <br /> needed to determine whether new potential sources of contamination may be introduced in the future <br /> and to identify future actions for addressing these anticipated sources. Land and water use changes <br /> may introduce new contamination sources or result in changes to groundwater use and quality. The <br /> anticipated changes may occur within the jurisdictional authority of the city, although some may not. <br /> Table 4 describes the anticipated changes to the physical environment, land use, and surface water or <br /> groundwater in relationship to the 1)influence that existing governmental land and water programs and <br /> regulations may have on the anticipated change, and 2) administrative,technical, and financial <br /> considerations of the City of Pequot Lakes and property owners within the DWSMA. <br /> Table 4-Expected Land and Water Use Changes <br /> Expected Change Impact of the Expected Influence of Existing Administrative,Technical, <br /> (Physical Environment, Change On the Source Government Programs and Financial <br /> Land use,Surface and Regulations on the Considerations Due to the <br /> Water,Groundwater) Water Aquifer Expected Change Expected.Change <br /> Physical Environment: <br /> No major changes in <br /> the Pequot Lakes Does not apply Does not apply Does not apply <br /> DWSMA are <br /> anticipated at this time. <br /> Land Use: <br /> 1.
