Groundwater Collection Systems and One-Pass Trenching

In Canada’s western provinces, large potash mining operations are generating massive tailings piles containing high concentrations of salt. These tailings are stored within holding areas surrounded by dykes, but over time, the salt gradually leaches into the ground, posing a significant contamination risk. If left unchecked, the leachate could migrate offsite, threatening surrounding farmland and

Reactive Barrier ZVI Wall and One Pass Technology

A passive reactive barrier wall was installed to remediate groundwater contaminated with tetrachloroethylene (TCE) at a site in a busy commercial center. This project posed unique challenges due to its location, where tight site parameters and ongoing business operations required a careful approach to minimize disruption. The site’s geology consisted of sand and clay layers
