Series 8: Fracturing for Site Cleanup
See our Newsletter, Environmental Enlightenment #200, for introduction to one highly valuable, plainly written series of Citizen’s Guides published by the EPA at http://www.clu-in.org/products/citguide
With this issue we introduce the EPA’s Citizen’s Guide to Fracturing for Site Cleanup. You can reach it through the hyperlink under the blue header below.
Environmentally, fracturing has become a loaded word.
One should differentiate between fracturing for exploration of oil and gas and fracturing for remediation of contaminated soil or groundwater.
It’s the same word, but with applications wide apart.
Formations that contain oil and gas are deep, on the order of hundreds to thousands of feet.

And they involve complex operations injecting fraccing fluids and treatment or decontamination of millions of gallons of wastewaters generated in the process.

Formations contaminated from man-made spills are shallow.
Fracturing to clean up contaminated sites operates in depths on the order of tens of feet and rarely exceeds 100 feet .
