Spill conditions: This
oil spill on 7 April 2000 offers a case example where marsh restoration
was made as part of the response effort to successfully enhance
environmental recovery at a marsh heavily contaminated from a pipeline
break (126,000–139,000 gallons of Numbers 2 and 6 fuel oils,
>46,000 gallons eventually recovered). Marsh operations guided
by U.S. EPA included mechanical trenching, limited low-to-moderate
pressure flushing, hand recovery using sorbent pads and working
from placed boardwalks, and the aerial application of fertilizer
(bio-stimulation). Excellent
marsh recovery (indicated in photos below) has occurred 1 and 2
years later.
