Sediment Management Options Report (Final)
Final Sediment Management Options Report for the recommended approach to manage the PCB contaminated sediment at Lyons Creek East, Welland.
Final Sediment Management Options Report for the recommended approach to manage the PCB contaminated sediment at Lyons Creek East, Welland.
Report produced by Terrastory outlining the ecological study conducted to characterize baseline ecological conditions and natural heritage features within sections of Lyons Creek East (LCE) affected by legacy sediment contamination.
This summary outlines the sediment management options that were considered and the recommended sediment management plan for remediation of PCB contaminated sediments in areas of Lyons Creek East. A full presentation of the information will be presented on June 18, 2025 in Welland, ON.
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 detailed inventory of wetland and aquatic features of the Lyons Creek East wetlands. This study incorporated existing background data, remote sensing and field inventories of vascular plants, vegetation communities, breeding amphibians, and breeding birds to catalogue the terrestrial and aquatic resources present, establish baseline conditions, and identify sensitive features and functions.
