REMEDIATION OF CONTAMINATED SEDIMENT AT THE PORT OF GASPE-SANDY
BEACH (QUEBEC)

SUMMARY:
Over the last 15 years, the sea floor in the area adjacent to
the wharf at the Port of Gaspé- Sandy Beach has undergone
characterization studies and a toxicological and
ecotoxicological risk assessment. Characterization studies of
the sea floor have brought to light a contaminant plume of
copper (Cu), with the highest concentrations found immediately
south of the wharf and a decreasing concentration gradient to
the east, extending as far as the point on the Sandy Beach
sandbar to the northeast. These same studies have also brought
to light the presence of an area around the wharf that is highly
contaminated with polycyclic aromatic hydrocarbon (PAH), within
a radius of approximately 300m

Ecotoxicological studies have helped to establish the Integrated
Effect Levels, or IEL, for sediment in the area of the wharf at
the Port of Gaspé - Sandy Beach. The IEL are defined as the
criteria for restoration of the seafloor; specifically, this
means 2,400mg/kg for copper and 5mg/kg for total PAH. 

In order to remove the contaminated sediment that exceeds this
criterion, Transport Canada proposes to dredge the contaminated
sediment and conduct the final onshore management of dredged
material offsite. The volume of contaminated sediment to be
dredged, including both required and optional work, totals
approximately 27,330m3 in place, to which additional dredging
may be added (approximately 2,500m3). Based on available
characterization studies, Transport Canada has established
eleven (11) dredging polygons. These polygons are defined by a
dredging thickness and horizontal limits.

Transport Canada's objective is to remediate the seafloor in the
sector adjacent to the wharf in the Port of Gaspé-Sandy Beach
while minimizing the environmental impact of the work. The
achievement of dredging is planned from July 2015 and if
required, may be completed during 2016. All project work,
including dredging and final materials management, must be
completed before the end of 2016.
