Purpose: to (1) quantify the sediment input to LCE, to assess the rate of accumulation, and to predict the period of time required to accumulate given a depth of sediment; and (2) determine the max. flow velocity in the system that could be sustained without re-suspending bottom sediments and potentially exposing PCB contaminated sediment to erosion.

A joint study was undertaken by Environment and Climate Change Canada, and the Ministry of the Environment, Conservation and Parks to address and document the sediment and water quality in Lyons Creek East.
The study was undertaken in 2 parks; 1. a screening survey to identify areas with elevated PCBs, and 2. a survey that included sediment cores, caged mussels, and fish collections to understand…
