Former Titan 1A Missile Site Permanganate

Former Titan 1A Missile Site Permanganate Pilot Test
Lincoln, California

Burleson conducted a study of in situ chemical oxidation and enhanced bioremediation for the Titan 1A Missile Site in Lincoln, California, as a subcontractor to Brown & Caldwell. Tasks included evaluating the existing groundwater extraction system at the site and determining whether in situ treatment would accelerate trichloroethene (TCE) remediation.

Burleson prepared a work plan to conduct field activities and bench scale tests. Site soil and groundwater were well characterized through previous investigations; however, to effectively evaluate site conditions that could be impacted by in situ technologies, additional site soil and groundwater were collected. Sufficient samples were collected for analysis of metals and secondary water quality parameters that could be affected by in situ technologies, and to conduct bench scale tests. Bench scale tests were completed for permanganate oxidation and hydrogen releasing compound (HRC) reductive bioremediation treatment. Burleson reviewed test results and completed a summary report with recommendations. Results from the bench scale tests indicated that both chemical oxidation (using potassium permanganate) and enhanced bioremediation (using HRC) could effectively treat TCE in site groundwater. Byproduct formation and changes in water quality were observed in both bench scale tests that would need to be addressed in a pilot test design.

Chromium was mobilized from soil into groundwater during permanganate oxidation, but slowly attenuated when in contact with untreated soil.

Vinyl chloride was produced as a byproduct of reductive bioremediation. Complete dechlorination of vinyl chloride, a TCE breakdown product, would be expected in a pilot study but could occur at a relatively slow rate.

Burleson recommended that pilot studies for either in situ technology include sampling points to evaluate byproduct formation that could also act as extraction wells for hydraulic control if required. Burleson also abandoned five monitoring wells at the site under contract with the USACE, Sacramento District.

Client Satisfaction

"Burleson Consulting was excellent to work with and very professional. They assembled a top-notch team of experts to study and propose solutions to the water supply challenges at Sutter National Wildlife Refuge. The communication was excellent throughout the project. This included project staff, contracting personnel, and interested stakeholders. As a result, the project was completed on time and on budget. I would not hesitate to use or recommend Burleson Consulting in the future."Kevin Clancy, Project Manager – United States Bureau of Reclamation

"Burleson provided exceptional services under this contract. Because of their successful work, they were awarded a $7M follow-on IDIQ contract in 2014, that also encompasses biological monitoring at former Fort Ord. They have consistently improved their plant material collection and propagation techniques and pass the savings onto the federal government. Burleson is a valuable team member on Fort Ord and I feel that they are true stewards of the environment." William K. Collins, BRAC Environmental Coordinator, US Army Corps of Engineers

"Burleson has been able to work with several government agencies (to include tribal groups and natural resource trustees) and several responsible parties to assist in progressing this site to a stage where technical and agency concerns can be identified and resolved. Strengths – overall and in depth understanding of mine site and CERCLA dynamics. Deficiencies – none. I would not hesitate to use Burleson." Daniel McMindes, USACE Liaison to EPA, US Army Corps of Engineers

"Burleson helped to manage the Sacramento Area Voltage Support Environmental Impact Statement. They came through and were always available during an ‘energy crisis’ in California. I will continue to work with them."Loreen McMahon, Project Manager - California Public Utilities Commission

"We appreciated Burleson’s great work, re: completing the draft EIR on the scheduled date (it was a tremendous task, but they completed it). All of them put a lot of work into it (it was a true team effort). They should all be proud of this accomplishment given the changes and obstacles encountered along the way, and I cannot thank them enough."Glenn M. Shuder, AIA, CFM, Chief Architect - Project Director, SMUD

"We chose Burleson Consulting because of their experience with the specific project matter in technical and regulatory issues and for their record of excellent communication skills in complex, multiparty projects. They were responsive to the matter and were sensitive to all relationships between the parties involved."Kevin Mayer, PE, Project Manager - USEPA
