EXPLORING OPTIONS FOR REAL-TIME WATER QUALITY MONITORING WITHIN GREAT LAKES PORTS

Abstract

This technical report presents findings from the exploration of available environmental monitoring sensors, the piloting experience of long-term field deployment of the Proteus multiparameter sonde developed by Proteus Instruments, and the development of an accessible platform for viewing real-time data in support of uptake avoidance best management practices as defined by the U.S. Environmental Protection Agency’s 2013 Vessel General Permit. Project staff conducted a literature review and investigation of commercially available sensors and selected an instrument that consists of a multiparameter sonde—able to measure turbidity, chlorophyll-a, phycocyanin, and total coliform bacteria—, telemetry system, and solar panel. Long-term deployment of the Proteus began in April 2022 and ended in October 2022 at the Montreal Pier Testing Facility located on the Duluth-Superior Harbor in Superior, Wisconsin, USA. Data collected from the multiparameter sonde was transmitted and stored on Outpost.com and real-time data was made publicly available using Web AppBuilder for ArcGIS. This piloting experience has shown promise to provide real-time data in support of uptake avoidance practices.
