Sediment/Biological Assessment of Lyons Creek East

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.

Lyons Creek East Sediment Transport Study

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.

Delisting Strategy: Niagara River (ON) Area of Concern

This document was developed to provide the most up-to-date summary of information about the Niagara River’s remaining BUIs, provide guidance for applying specific delisting criteria, and identify the remaining priority actions and appropriate lead organization(s) involved in the RAP who will implement the activities for each impairment.

Biomonitoring Study of Lyons Creek East (2002-2003)

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…
