Track 2 Day 2: Latter Prahl


Navigating Environmental Monitoring on the Trent-Severn Waterway

Thursday March 26, 2020
2:00 to 2:30 p.m. (Hall F)


Myles Latter and Jeremy Prahl, Cambium Inc.


In 2017, the Government of Canada announced $330 million in construction contracts for Trent-Severn Waterway (TSW) infrastructure. This presentation outlines the struggles, successes, and lessons learned while working on over 30 TSW projects, keeping erosion and sediment control as the focus.

Challenges included very strict and short timelines for project deliverables; environmental sampling requirements typically performed in a laboratory that need to be sampled real-time in the field; implementing provincial environmental legislation or best management practices on Parks Canada lands; and managing erosion and sediment controls in an ever-changing work environment under high flow water conditions.

Cambium Inc. successfully faced these challenges by utilizing knowledge sharing, creativity, collaborating, and being adaptable.

Case studies will be presented on the following topics:

  • Producing Environmental Management Plans in as little as 24 hours
  • Creating correlation relationships for turbidity and total suspended solids (TSS) to meet environmental sampling requirements
  • Implementing environmental legislation and best management practices on Parks Canada lands, specifically in regards to Osprey nests
  • Creating comprehensive and adaptive erosion and sediment control plans to monitor in-water work like dredging and cofferdam installations


Learning Objectives

1. Learn how to respond to short timelines and last-minute contractor requests.

2. Understand how creativity and knowledge sharing were used to monitor TSS in the field.

3. Learn about the implementation of Provincial environmental policy on Parks Canada lands.
