This report provides insight on PCB contamination trends in Lyons Creek East using common snapping turtles (Chelydra serpentina) as a bio-indicator. Prepared by: K.D. Hughes & S.R. de Solla, Ecotoxicology & Wildlife Health Division, Environment & Climate Change Canada, May 15 2024.
This report is a compilation of Ministry of the Environment (MOE) studies on the
Polychlorinated Biphenyl (PCB) and metal contamination of Lyons Creek sediments east of the
Welland Canal.
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…

Concern) from 2002-2003. Prepared by Danielle Milani and Lee Grapentine, Environment Canada, Aquatic Ecosystem Impacts Research Branch, NWRI Contribution No. 06-414
Report on the results of sediment chemistry, benthic community structure, bioaccumulation in native invertebrates, and sediment toxicity from fall 2015 sampling at Lyons Creek East and three nearby reference sites. Analysis also includes trends from 2002-2015. Prepared by Danielle Milani and Lee Grapentine, Environment and Climate Change Canada, Water Science and Technology Directorate, March 2017
Report on the results from Environment Canada’s sampling efforts at Lyons Creek East as part of the monitored natural recovery which was selected as the option for the management of the contaminated sediments. Prepared by D. Milani and L. Grapentine, Environment Canada, Watershed Hydrology and Ecology Division, March 2014.
