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,

The inner core remains at an estimated temperature of greater than 5,000ºC. Interesting Fact: Moving up a mountain results in a temperature decrease of about 0.7ºC per 100 m of

Dry Cleaning Fluids: A Brief History

Ancient Greeks and Romans used grease-absorbent earths and sands on clothing; the term “dry-cleaning” was likely coined as a result. Interestingly, this is where the term “fuller’s earth” originated. A fuller was a textile worker who, among other things, kneaded these materials into woollen cloth to absorb oils as part of the finishing process. Before

The Dirt on Dry Cleaners

Or…Removing a Stain on the Environment For decades tetrachloroethylene (a.k.a. perchloroethylene, PCE or perc) was favoured as a dry cleaning fluid due to its strong degreasing power, relatively gentle action on fabrics, and non-flammable nature. In time, scientists came to understand the health and environmental impacts of perc releases into soil and groundwater. Perc itself
