While Pneumatic Fracturing, Inc. (PFI) is no longer in business as many of you knew it, I have taken the experience and expertise that I have gained since 1995 and moved on to an innovative, cutting edge company, GeoSierra Environmental, Inc. My wealth of pneumatic fracturing knowledge will be coupled with GeoSierra’s extensive capabilities in the hydraulic fracturing arena. Merging our collective knowledge creates a one-stop shop for our national clients where the options that can be provided are not limited to any one approach. My new team offers outside the box thinking where the remedial solutions that can be implemented are endless so keep checking our website for new updates and learn about our extensive capabilities at

And for those of you who are new to the technology or did not know PFI, my experience includes a wide range of environmental remediation services, including the subsurface delivery of remedial amendments using innovative techniques such as:
· pneumatic fracturing,
· pneumatic dry and liquid injection of amendments,
· directional injection, and
· performance verification of our projects, demonstrating radius of influence and subsurface distribution.

PFI provided services to consulting, government and private organizations nationwide, focusing on the application of the patented Pneumatic Fracturing and Pneumatic Injection technologies. Our mission was dedicated in providing complete and satisfactory remediation of sites that presented an unusual challenge. We were not just another fracturing company – we prided ourselves on being Responsive, Adaptable, Skilled and Innovative.

So while PFI as a company is no longer and the links on the left of this website are merely for informative purposes, I wanted to thank each and every one of my clients and contacts that I have fostered since the inception of PFI and let you know that I look forward to continuing my working relationship with each one of you for many years to come. Without you, my personal success and the inherent knowledge I gained would not have happened so easily.

Sincerely - Deborah L. Schnell, P.E.
