Alyson joined Vertex Environmental in September 2020 as a Field Technician, working on various in-situ chemical oxidation (ISCO), chemical reduction (ISCR) and Trap & Treat® projects across Ontario and in BC. Before joining the Vertex team, Alyson completed a PhD
Sewer Discharge Agreements: Choppy Waters or Smooth Sailing?
The municipal permitting process for Sewer Discharge Agreements (SDAs) can be complex and frustrating at times. Ontario operates under a patchwork of different regulations where every municipality has its own unique permitting process. Some two-tier municipalities have separate application processes
Residential Condominium SDA Case Study
Background: A new residential condominium development in Toronto with three levels of underground parking levels. The developer retained Vertex to prepare dewatering and groundwater treatment plans, and to process two sewer discharge agreement (SDA) permits to cover both the short-term
Demonstration Day 2022
Thanks to everyone who came out to the joint Vertex Environmental and Strata Drilling Group Demonstration Day held on October 21, 2022! We held the inaugural one last year in Kitchener, but not everyone who wanted was able to attend,
Permeable Reactive Barriers: Quality Data Gathering creates Robust Designs
In the environmental industry the Permeable Reactive Barrier, or PRB, is a well known technology/strategy when dealing property boundary management and off-Site liability risk for mobile groundwater impacts. In fact, Vertex has already written about these technologies a few times
Using LLMiHpt to Optimize the Design of a Permeable Reactive Barrier
Over 300 years ago Alexander Pope said “a little knowledge is a dangerous thing”. In the case of many subsurface characterization programs being completed today, too little data is also a dangerous thing. It can result in wasted time, energy
Pump & Treat Systems: A Resurgence
When it comes to fashion, vintage trends always seem to come around again and again. When it comes to remediation, different technologies are popular for a time and then settle into more of a niche application, as they are supplanted
Case Study: P&T Enhanced ISCO – A Multi-Technology Approach for a Challenging Site
The following case study is a good example of how a Pump & Treat system was used to enhance the natural hydraulic gradients at a site to effectively pull chemical oxidants across an otherwise inaccessible area and facilitate the destruction
Delivering Success: Remediating Bedrock and Other Complex Geologies!
Have you ever encountered a site where difficult subsurface conditions left you wondering whether remediation was even possible? Maybe the site had impacts in bedrock or other tough stratigraphy such as flowing sands, cobbles and boulders, and/or tight tills. These
Bedrock Remediation Cast Study – Where There’s a Will There’s a Way
Overview The site was formerly operated as a steel manufacturing facility that included historic degreasing operations and chemical storage. Environmental investigations identified the presence of chlorinated solvents, including trichloroethylene (TCE), dichloroethylene (DCE) isomers, and vinyl chloride (VC), in groundwater
