Activated Carbon: New to In-Situ Remediation

In the past couple of years in Canada, specially formulated activated carbon (AC) based remedial amendments have effectively contained and treated petroleum hydrocarbon and chlorinated solvent plumes. Three brief case studies are presented in this article showcasing the power of activated carbon during in-situ remediation applications. From the Vertex Vault: Activated Carbon – What It

Activated Carbon – What It Is and How It Works

  Charcoal is produced by heating wood or other organic materials in the absence of oxygen at temperatures above 300⁰C. Early methods consisted of constructing earthen kilns over stacked wood. The wood is partially burned to generate heat. Heating continues until only residual carbon and inorganic ash remain. The original vascular structure of the plant

Treating a Plume with One Injection

A single injection has been used to effectively contain and treat petroleum hydrocarbon and chlorinated solvent plumes using a specially formulated activated carbon (AC) based technology. This result has been documented at hundreds of sites. It’s a welcome result over some in-situ chemical oxidation methods (which can still be very applicable!) where multiple injections are

Just Back From B.C.

We just returned from our 3rd Annual trip out to B.C. to host the SMART Remediation Conference in Vancouver. We love to take in the benefits of the B.C. lifestyle while there, including the fresh seafood and the amazing skiing at Whistler! We were jumping for joy. Highlights of conference included Alan McCammon of the

Wait, Don’t Throw That Out! The Beneficial Reuse of Soils Just May Be A Better Way To Go

When contaminated soils are an obstacle to a property transaction or redevelopment, the fastest approach is usually to dig out the soil and then haul it away. But that last step might be rash – and costly. And it unnecessarily uses up valuable landfill space! There are many scenarios where on-site treatment will be preferred.

Finally, We Have Permeable Reactive Barriers for Petroleum Hydrocarbons!

When environmental practitioners hear the term Permeable Reactive Barrier (PRB), likely an “iron wall” most often comes to mind. This is not surprising since iron PRBs have a long history – they were installed as early as 1995 to treat dry-cleaning solvents. PRBs intercept and treat contaminated groundwater plumes. They are passive and sustainable systems,

Canadian Know-How Helps Move Remediation Projects Ahead All Winter Long

As Canadians, we love to talk about the weather. It changes dramatically across the seasons and directly impacts our work and play time. Three feet of blowing snow may tend to force us indoors for Netflix marathons. But work still calls. It has been estimated that 50% of all construction activities are sensitive to weather
