Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Wellhead Water Resource Protection Areas are surface and sub-surface areas surrounding public water supply wells or wellfields where the quantity or quality of groundwater moving toward such wells or wellfields may be adversely affected by land use activity. Such activity may result in a reduction of recharge or may lead to the introduction of contaminants to groundwater used for public supply.</SPAN></P><P><SPAN>Three classes of Wellhead Water Resource Protection Areas are shown on the maps.</SPAN></P><P><SPAN>Class A - The area within a 300-foot radius circle around all public water supply wells which are classified as water systems, as defined by Section 22.146 (Public Water Systems) in the State of Delaware Regulations Governing Public Drinking Water Systems. Class A wells are community, transient non-community, and non-transient non-community.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Class B - The Glendale and Eastern States Wellfields. These Wellhead Protection Areas have been delineated through the use of hydrogeologic mapping, analytical methods, and application of U.S. EPA modular semi-analytical models using a five-year time-of-travel by the Delaware Geological Survey as discussed in a report prepared by the Delaware Geological Survey entitled "Application of the EPA WHPA Models for Delineation of Wellhead Protection Areas in the Glendale and Eastern States Wellfields, New Castle County, Delaware" dated January 1993.</SPAN></P><P><SPAN>Class C - Wellhead Protection Areas delineated by the Delaware Geological Survey and the Delaware Department of Natural Resources and Environmental Control through the interpretation of geologic and hydrologic reports and maps, water-table maps, and professional judgment. Such areas are considered preliminary designations.</SPAN></P></DIV></DIV></DIV>
