REMEDIAL DESIGN/ REMEDIAL ACTION

 

Summit completes remediation system designs (RD) and remedial actions (RA) for surface and subsurface contamination with a phased approach. Using data gathered during a remedial investigation and remedy selection from a feasibility study, Summit typically proceeds with the following phases:

• Preliminary design and pilot testing;
• Completion of the final RD;
• Implementation of the RA; and
• Site closure.

Summit’s design engineers and experienced field staff utilize previously gathered data in clarifying and defining the RA requirements. We prepare the final design and engineering information needed to apply for regulatory permits and funding sources. Summit completes construction specifications showing the character and extent of the project and obtains competitive bids for implementation of the RA.

We follow the RA to site closure using Summit technicians, or Summit will train your staff to complete the implementation. Summit prepares and submits status and closure reports which include results of data collected during the implementation and site monitoring.

Product Recovery Systems

This free-phase product recovery system utilizes a 100 gallon per minute groundwater treatment system. The system incorporates an aeration tank, packed tower air strippers, and granular activated carbon filters to maintain effluent concentrations below discharge limits. The effluent from this system was discharged on site to an infiltration trench eliminating the need for more costly effluent disposal.

Experience

Summit has successfully completed and implemented RD/RAS at over 1,000 sites throughout the United States. We have experience with remediation of chlorinated and non-chlorinated volatile organic compounds (VOCs); petroleum products, including recovery of non-aqueous phase liquids (NAPL); and inorganic contaminants such as metals, nitrates, and corrosives. Remediation technologies utilized by Summit include:

• Phytoremediation
• Oxygen Release Compound Injection (Geoprobe®)
• Air Sparging
• Slurry Wall/ Barrier
• Soil Vapor Extraction
• Low and High Temperature Desorption
• Groundwater Pump and Treat
• Soil Bioremediation
• NAPL Recovery
• Soil Spreading and Landfarming

Our ability to successfully combine innovative technologies with standard engineering practices enables us to produce cost effective RD/RAs for our clients. Additional cost savings and improved efficiency may be realized during operation of a remediation system by utilizing remote monitoring and Supervisory Control and Data Acquisition (SCADA). This technology enables instrumentation and control units at your site to be accessed via modem or radio. Current conditions are observed remotely from your office in real-time. Operation of process equipment can be adjusted remotely while the results of modifications are directly observed, and historical information is downloaded into a database or Geographical Information System (GIS).

We believe in thorough characterization of the subsurface and providing flexibility in RA design and operation. This allows us to adjust to changing site conditions and reduce the time to closure, therefore reducing overall costs and improving client service.
