Spatial-determinants of deteriorating water quality in the Vermilion River, by Carrie Strangway, UOIT

Spatial-determinants of deteriorating water quality in the Vermilion River, by Carrie Strangway, UOIT

As part of the Lower Vermilion Source Water Quality Monitoring Project, funded through a 3-year Ontario Trillium Foundation grant, Carrie Strangway completed her Master’s Thesis in partial fulfillment of the requirements for a degree of Master of Science in the Faculty of Science, Applied Bioscience, University of Ontario Institute of Technology.  What follows is a poster of her more detailed manuscript, which will be published shortly:

Abstract 

The Vermilion River and major tributaries (VRMT) receive various point and non-point inputs, in addition to several flow regulation features, along their continuum. Further development in the Vermilion watershed has been proposed, raising concerns about cumulative impacts to the ecological health of the VRMT. To assess the current state of riverine health, water quality metrics were monitored monthly at twenty-eight sites during the ice-free period of 2013 and 2014. Generation of landscape-scale data revealed a broad range of land-cover and road density in the watershed at differing landscape-scales. Sites on the main-stem of the Junction tributary had above average concentrations for the majority of water quality parameters measured, specifically, sites within Copper Cliff Creek and Junction Creek (i.e. CC- 12 and JUN-13) were the most impacted. The river network pathway (i.e. asymmetric eigenvector map (AEM) eigenfunctions) and topographical features (i.e. catchment land-use) explained most of the variation in water quality (62.2%), thus both proved to be useful spatial determinates of deteriorating water quality.

THANK YOU ONTARIO TRILLIUM FOUNDATION, KGHM INTERNATIONAL & CONSERVATION SUDBURY FOR YOUR SUPPORT!!!

The Lower Vermilion Source Water Quality Program is a 3 year study to characterize the lower Vermilion River to identify all negative inputs and outputs affecting water quality, and to ultimately recommend a course of action to protect and restore water quality on the Vermilion River system.
