| How to Use Hydraulic Fractures as Remediation Tools |
 |
| Hydraulic fractures can be filled with massive amounts of treatment materials of various types. |

A variety of processes have been developed to address subsurface contaminants. Certainly, sites can be (and have been) excavated, and the recovered dirty soil treated or hauled to a safe place. In situ methods avoid the cost and disruption of excavation. Our services support in situ technologies by placing (injecting) large volumes of treatment materials into contaminated soil or bedrock at specific, targeted locations and elevations. Inasmuch as we offer delivery techniques, we can support a variety of remediation methods (e.g. ISCO, bioremediation, or SVE) in any geology to attack diverse contaminants.
The details of how treatment materials and processes interact with the contaminants are, in the end, matters of hydrology. In general, three kinds of hydrological processes are enabled or enhanced.

- Hydraulic fractures can offer ten-fold improvement in the performance of wells used either to recover contaminants or to deliver treatment fluids into targeted formations. Click here for more information.
- Hydraulic fracturing can be used to construct passive reactive barriers (PRB's) at greater depths and with less disruption than trenching methods. Click here for more information.
- Massive amounts of treatment materials can be placed at targeted locations within contaminated media, and these structures can serve as cost-effective, persistent yet passive sources of in situ reagents. Click here for more information.
