Potomac Continuity
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Number of studies present cross sections that include geophysical logs (gamma ray, spontaneous potential, resistivity) that can be used to evaluate sand-body continuity within the lower Potomac aquifer (Hansen, 1968; Brown and others, 1972; Cushing and others, 1973; Trapp and others, 1984). These cross sections indicate that a number of thicker sands are continuous. Cushing and others (1973, their plate 2) generated a map showing the thickness distribution of a major sand unit in the Potomac aquifer. This map, which is digitized, demonstrates that the major sand bodies are continuous, and for this particular interval, are more than 50 ft thick across the entire Delmarva Peninsula. </SPAN></P><P><SPAN /></P></DIV></DIV></DIV>
