Five thousand gallons of gasoline spilled
on Maine’s Route 11 in 2011. As of the end of July 2012, the remediation effort
has been scaled back, according to this report.
The accident happened when a tanker truck carrying more than
8,000 gallons of gasoline rolled over near Wallagrass and spilled about 5,000
gallons. As of mid-July 2012, 2,300 gallons of gasoline had been removed and
because of diminishing returns from the southern vapor extraction system, the
Maine Department of Environmental Protection shut it down July 12. The northern
extraction system had previously been turned off, but weather conditions
prompted the department to turn it back on.
The DEP is leaving monitoring wells in place for at least
another year. One local well owner had elevated levels of contaminants
associated with gasoline and the well has been fitted with a carbon filtration
system. Still, the DEP may require new drinking water wells to be drilled.
