<p class=MsoNormal><em><i><font size=3 face="Times New Roman"><span
style='font-size:12.0pt'>Abstract:</span></font></i></em> The cleanup of ground
water at the Massachusetts Military Reservation on <st1:place w:st="on">Cape
Cod</st1:place> is one of the most visible and expensive of the Department of
Defense's environmental restoration projects. More than two dozen plumes of
industrial solvents, explosive compounds, fuel compounds, and perchlorate
extend up to several miles from the reservation toward coastal streams, ponds,
and wetlands. In 2007, more than 20 years after the cleanup effort began, about
20 million gallons per day are pumped from 68 wells to contain and remediate
the plumes. <br>
The cleanup is the product of many years of complex
interactions among scientists, engineers, water managers, regulators, and the
public. Everyone agreed that sound science was necessary to support the
cleanup, but they also wanted quick action to protect “<st1:place w:st="on">Cape
Cod</st1:place>'s Quabbin.” The speaker, a hydrologist who has served
for more than thirty years with the USGS, will examine how studies to
understand the <st1:place w:st="on">Cape</st1:place>'s hydrology were
interwoven with the cleanup's engineering and policy decisions, and how cleanup
actions sometimes outpaced that understanding. When the aquifer will be
“clean enough” remains an unanswered, potentially controversial
question. <font color=black><span style='color:black'><o:p></o:p></span></font></p>
