MARATHON – Environment – Marathon, Pic River and area residents may have noticed boats operating  in  Peninsula  Harbour  and  wondered  what  they  were  doing.  The increased vessel traffic results from an extensive suite of environmental monitoring  taking  place  this  summer  in  Marathon’s  main  harbour  on Lake Superior – Peninsula  Harbour.

The Ontario Ministry of the Environment and Climate Change and Environment and Climate Change Canada are cooperating to carry out monitoring related to the $7 million “thin-layer cap” remediation project for  harbour  mercury  and  PCB  contamination.  This  project  was completed  in 2012.

Monitoring is mean to  quantify:

-whether the cap is mixing with native lake-bottom sediments

-whether the cap is meeting remedial goals to decrease average mercury concentrations

-whether native aquatic life and plants are re-colonizing the area of clean fill deposited in Peninsula Harbour during the 2012 capping process.
