Oct. 19 – Peninsula Harbour Monitoring Presentation
Posted on: September 16, 2016
Peninsula Harbour Capping Project
Sand and aggregate are lowered from a barge into Peninsula Harbour within the confines of a “silt curtain.” This work was part of a 2012 project to cap contaminated harbour sediment.

A summary of environmental monitoring data collected in Peninsula Harbour, the main harbour at Marathon, Ontario, will be presented between 12 noon and 1:30 p.m. on October 19th at Marathon Town Hall. The presentation is being made to provide information about the health of the Peninsula Harbour ecosystem.

In 1987 Peninsula Harbour was designated as one of several locations around the Great Lakes where cleanup actions were required to address environmental issues. This designation was part of the Remedial Action Plan (RAP), a program put in place by Canada and USA to clean up the Great Lakes. Concerns centered on mercury and PCB contamination, degraded fish and benthic communities (bottom dwelling organisms living in harbour sediment) and aesthetic issues like large quantities of foam, sometimes over a meter thick, on the harbour surface. A community liaison committee, based in Marathon and nearby Pic River and chaired by Dr. Sarah Newberry, provided local perspective and assistance as cleanup proceeded.

In 2012, Environment and Climate Change Canada and the Ontario Ministry of the Environment and Climate Change completed a $6 million project to cap contaminated harbour sediment with clean sand and aggregate. Monitoring data to be presented will include information related to environmental recovery in the area of this cap, which covers the area of highest contamination within the harbour.

Data will be presented by representatives of government agencies supporting the Remedial Action Plan, namely Environment and Climate Change Canada, the Ontario Ministry of the Environment and Climate Change and the Ontario Ministry of Natural Resources and Forestry.

The event is being hosted by the Peninsula Harbour Remedial Action Plan, coordinated by Lakehead University through its Department of Geography and Environmental Science.
