Description: <DIV STYLE="text-align:Left;"><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>Several authors presented descriptions of the mineral composition of the lower Potomac interval (Anderson, 1948; Kasabach and Scudder, 1961; Maher and Applin, 1971; Trapp and others, 1984; Benson and others, 1985). These studies indicate that the sands of the lower Potomac aquifer contain low proportions of reactive minerals such as calcium plagioclase and calcite; however, glauconite is present. In addition, studies indicate that because the formation waters have been in place for &gt;15,000 yr, they have most likely approached equilibrium with the surrounding formations. We therefore conclude that the potential for significant rock/water reactions with high CO</SPAN></SPAN><SPAN><SPAN>2</SPAN></SPAN><SPAN><SPAN> fluids for eastern New Jersey, Delaware, and Maryland are low to moderate.</SPAN></SPAN></P><DIV><P><SPAN /></P></DIV></DIV>
