Since 1983, the Ontario Ministry of Environment, Conservation, and Parks monitored contaminants in the Niagara River using caged mussels and (more recently) semi-permeable membrane devices. This report summarizes data collected in 2015 which was aimed at identifying sources of contaminants specific to the Niagara River.
Niagara River Biomonitoring Study 2012: Caged Mussels and Semi Permeable Membrane Devices (SPMDs). Prepared by Lisa Richman, Ontario Ministry of Environment, Water Monitoring Section, Environmental Monitoring and Reporting Branch, Nov. 2015
Results from the Niagara River Upstream/Downstream program to measure the concentrations/loads and trends of contaminants in the river, 2001-02 & 2004-05. Data are compared to the most stringent water quality criteria available from the four agencies, to provide an indication of potential impairment of beneficial uses. Use of these data for any other purpose is at the discretion of the user.
