Added to this is our six year working history with USACE, including the Sacramento, Albuquerque, and San Francisco Districts. Projects with the EPA, NPS, and other Federal agencies add to our portfolio. Descriptions of Adanta’s representative Federal projects are provided below to illustrate our broad and relevant technical experience in meeting our clients’ most challenging requirements.

Feasibility Study and Erosion Control, NAS Jacksonville, Jacksonville, FL, NAVFAC Southeast

Adanta is conducting a feasibility study at the Building 200 Wash Rack Former Disposal Pit (PSC 45) located in the northern industrialized portion of NAS Jacksonville. An interim remedial action of a soil excavation was conducted in 2014. The feasibility study will consider all feasible remedial alternatives and compare them to the 9 National contingency plan (NCP) criteria to determine a selected remedy, including the following: long and short term effectiveness, reduction of toxicity, mobility or volume, implementability, compliance with (applicable or relevant and appropriate requirements (ARARs), overall protection of human health and the environment, and cost. Additionally, soils have been eroding at two other sites on the base. Adanta will prepare an Erosion Control Work Plan, which will be reviewed by the Partnering Team. Following approval, Adanta will install selected controls to address erosion issues at the sites.

Basewide Background Study, NAS Jacksonville, Jacksonville, FL, NAVFAC Southeast

Adanta is conducting a Basewide soils background study at NAS Jacksonville to address target analytes whose background levels were not established in an earlier RI/FS. During the study, Adanta is (1) evaluating existing facility data to identify background target analytes of interest and estimating associated concentration ranges of both natural and/or anthropogenic sources not related to activities conducted at the site; (2) analyzing exploratory data to identify the number of unique soil and sediment populations that are represented in the project database and to determine if there are sufficient existing data points for each target analyte of interest within each unique soil and sediment population to utilize statistical analyses designed to ensure a 95 percent confidence level for decision making; and (3) developing a revised background database that will enable the calculation of the BTVs for target analytes of interest and can be used to conduct a comparative statistical evaluation of site data against background data.

Data Gaps Site Investigation, Lorentz Barrel and Drum Superfund Site, San Jose, CA, USACE Albuquerque

Five-Year Reviews have revealed that soil and groundwater cleanup remedies for the site have not been fully successful in achieving their respective performance goals. The USACE technical team had questions about whether an additional source area is present at the site. EPA indicated that remediation strategies must be re-visited through another focused feasibility study (FFS). In order to identify remaining data gaps and complete the FFS successfully, Adanta is conducting an additional soil and groundwater investigation at the site to address primary contaminants of concern including 1,1 dichloroethylene and 1,4 dioxane. Additionally, Adanta will conduct sampling under the sidewalk at the site to assess the presence of PCB’s. Adanta will collect three discrete soil samples and one groundwater at each of 80 boring locations. The work will be completed in four separate mobilizations, the first two using rapid turnaround laboratory analyses, utilizing the “Triad” approach, whereby data will be quickly delivered to the numerous stakeholders, and consensus will be reached to locate the next set of borings.

Injection Well Installation and Oversight, RAAP, Riverbank, CA, USACE Sacramento

As part of the RCRA closure plan at RAAP, a former munitions manufacturing site contaminated with hexavalent chromium, Adanta installed 47 groundwater injection wells using a combination of Geoprobes, hollow-stem augers, and sonic rigs at depths of 50-100 feet for the in situ treatment of the contaminated groundwater using organic carbon and ferrous iron sulfate. Adanta’s Professional Geologist oversaw the well installation and associated soil logging. Adanta’s technical oversight and adaptability in using a variety of drilling methods ensured that well installation and contaminant treatment were conducted efficiently and effectively, helping to guarantee this complex project was completed on schedule and within budget.

Adanta prepared an Accident Prevention Plan and a Tier II Uniform Federal Policy Sampling and Analysis Plan, and is collecting groundwater samples, taking free product level measurements, and preparing monitoring reports for each site. Additionally, Adanta is supporting installation-wide restoration efforts by leading partnering meetings, and Land Use Control (LUC) Tracker and NIRIS development. As a testament to his satisfaction with Adanta’s work, the Navy RPM will extend the current contract for an additional year, including emerging contaminant (PFOS/PFOA) sampling.

Health and Safety Program Oversight for Industrial Water Treatment Plant (IWTP) Decommissioning, RAAP, Riverbank, CA, USACE Sacramento:

As part of the RAAP RCRA closure plan, Adanta provided a CIH to serve as a full time site safety and health officer for the demolition of the IWTP and associated equipment, as mandated by the USACE for projects of this magnitude. Specific duties included a daily site inspection to assess conformance with the site-specific H&S Plan, USACE 385-1-1 Safety and Health Requirements, Occupational Safety and Health Administration (OSHA), and Cal/OSHA requirements. Adanta also developed corrective actions for any deficiencies noted. The entire ten-week project was completed without any injuries or significant safety incidents, helping to guarantee tasks were completed on schedule and within budget.

Blue Angel FA-18 Plane Crash Remediation, Smyrna, TN, NAVFAC Southeast

The Adanta team is performing initial environmental response actions at a Blue Angel FA-18 plane crash site located near Smyrna, Tennessee. The aircraft contained approximately 1,500 gallons of Jet Fuel A, 355 ounces of oil, and 11.5 gallons of hydraulic fluid at the time of the crash. The crash site is predominantly on the Historic Sam Davis Home and Plantation. The scope includes (1) delineating and remediating petroleum-impacted soil, trees, and debris resulting from the aircraft crash to State of Tennessee regulatory requirements to obtain a “No Further Action” letter from the respective State agency, Tennessee Department of Conservation, Division of Remediation; and (2) restoring the crash site, stockpile area, laydown area, fencing, and other areas disturbed by the crash, resulting fire, and the Navy’s reclamation efforts. A professionally qualified archaeologist is monitoring the project and assessing potential impacts on cultural resources, and is maintaining contact with the NAVFAC SE Historic Preservation Officer (HPO) during the course of archaeological monitoring, providing weekly reports and an executive summary report at the conclusion of the project for submission to the HPO.

RCRA Reviews of Treatment, Storage, and Disposal Facilities (TSDFs), Multiple Locations, CA, USACE San Francisco and EPA Region 9

As the seed project for its $2.5M Environmental Services IDIQ for USACE South Pacific Division (W912P7-15-D-0002), Adanta evaluated TSDF’s to achieve EPA’s four environmental indicators (EI’s): human health, ground water, remedy construction complete, and cleanup complete. EI’s are measures that have been developed by the RCRA Corrective Action Program to track progress towards environmental cleanup of RCRA hazardous waste facilities. Adanta conducted RCRA reviews of TSDFs throughout California, including U.S. Navy Alameda Point Annex and Fort Hunter Liggett. Adanta worked with the California Department of Toxic Substances Control, Regional Water Control Boards, and EPA Region 9 to obtain background information and the most recent reports of activities at each facility in order to understand the history of the site, the current status, and plans for the facility to achieve their EIs.

Innovative Technologies and Methods for Improved Risk Reduction at Legacy Sites, 38 Sites Throughout the United States, NAVFAC EXWC (Port Hueneme)

Adanta is assisting NAVFAC EXWC and NAVFAC Headquarters in reviewing 38 legacy sites that have significant soil and groundwater impacts to identify opportunities to optimize the portfolio of sites from a response-complete-date, cost-to-complete, exit-strategy, and/or risk-reduction perspective. Among the sites covered are NS Newport (Rhode Island), ABL (West Virginia), NAB Base Little Creek (Virginia), MCAS Cherry Point (North Carolina), MCLB Albany (Georgia), NWIRP McGregor (Texas), NAS Jacksonville (Florida), MCB Camp Lejeune (North Carolina), NUWC Keyport (Washington), JBPHH (Hawaii), NSF Indian Head (Maryland), NS Bremerton (Washington), NAS Fallon (Nevada), FISC Norfolk (Virginia), NS Norfolk (Virginia), NWIRP Bedford (Massachusetts), NWIRP Calverton (New York), and MCLB Barstow (California). Many of these sites have ex-situ treatment (e.g. pump and treat systems) that have been operational for many years, but may no longer be effective. Other sites may have implemented in-situ treatment (e.g., bioremediation or monitored natural attenuation) to mitigate soil and groundwater impacts.


Adanta is critically reviewing site history, geologic setting, human health and ecological risk profiles, and the regulatory framework of the sites, and assisting Navy reviewers in identifying innovative ways of reducing risk, accelerating site cleanup, and reducing long-term remediation costs. Navy staff members have also provided preliminary recommendations for improvement. Adanta will review the site summaries and work with Navy staff to identify potential points of improvements in the Navy’s cleanup approach at the individual sites. As part of the process, Adanta’s staff will meet with Navy program managers in Washington D.C, conduct the reviews, collaborate with other subject matter experts, and provide a report with findings and recommendations.

Strengths, Weaknesses, Opportunities and Threats (SWOT) Analysis, North Carolina Military Installations, Multiple Locations, NC, North Carolina Military Affairs Commission (NCMAC)

Adanta was part of a team tasked to evaluate seven (8) military installations and surrounding communities in the state of North Carolina ahead of further BRAC downsizing. Evaluation factors considered included cost, capacity, training value, ability to mobilize and deploy from installation, value that the local community provides to the installation (e.g., schools, public works and services, childcare, housing, etc.). Installations evaluated included Fort Bragg, MCB Camp Lejeune, Seymour-Johnson AFB, MCAS Cherry Point, MCAS New River, CGS Elizabeth City, MOTSU, and the ARO. Adanta conducted installation visits, and community meetings and outreach events to gather information on the operations and involvement of the installation and surrounding communities. This information was analyzed and streamlined into reports illustrating strengths, weaknesses, opportunities, and threats to the surrounding communities during proposed military downsizing. The reports were provided to State of North Carolina officials to use in preparing a Strategic Plan to ensure that North Carolina was adequately prepared for future BRAC rounds and was the undisputed best state for military installations, missions, and the Defense industry.

Leaking Underground Storage Tank (UST) Compliance, sites throughout California, USACE San Francisco

As part of Cooperative Agreement LS99T10301 between EPA Region 9 and the California State Water Resources Control Board, more than 300 properties with abandoned USTs have been identified throughout California. EPA has further identified a subset of nine such sites in the Southern Central Valley for this project. Two of the sites are located in Kern County, and the other seven sites are located in Fresno County. In order to reduce the potential impacts that the USTs at these facilities might have on the local environment, EPA requested that the liquids from the USTs be pumped from the tanks and removed from the sites for proper reuse or recycling. Adanta is arranging for the removal and recycling of materials from the identified USTs, and the sealing of the UST fill ports. In support of the Abandoned UST Initiative, Adanta is (1) developing the project health and safety plan and work plan; (2) obtaining temporary EPA Hazardous Waste Generator ID numbers for each site on behalf of EPA; (3) providing technical oversight for the pumping of liquids; (4) performing in-situ UST abandonment (lugging and grouting of tank fill ports); (5) transporting removed liquids in accordance with US DOT requirements; (6) recycling removed liquids in accordance with EPA requirements; and (7) preparing a final project report detailing activities completed at each site

Groundwater Monitoring, Soil Sampling, and Site-Wide Restoration Support, Saufley Field, Pensacola, FL, NAVFAC SE:

Adanta is supporting on-going restoration efforts by conducting long-term groundwater monitoring at two sites at the former Saufley Field, along with soil sampling at a former skeet range for polycyclic aromatic hydrocarbons (PAH’s). Thus far, Adanta has installed two groundwater monitoring wells to prepare for planned emerging contaminant (PFOS/PFOA) sampling. Additionally, Adanta will provide other restoration support activities, such as addressing regulatory comments on previous reports, NIRIS, and LUC Tracker updates; and participating in the NAS Pensacola-Saufley Field Partnering Team.

Critical Review of Conceptual Site Models, Buckley AFB, Aurora, Colorado, and Edwards AFB, Rosamond, CA, AFCEC

Adanta provided critical reviews of draft Natural Infrastructure Conceptual Site Models (CSMs) prepared by Tetra Tech under contract to the AFCEC for Buckley and Edwards AFB’s. The CSMs describe lithological and hydrological conditions at each base as well as delineate potential sensitive receptors and possible communication between aquifers and/or surface water bodies. Adanta recommended a number solutions to clarify the intent and provide clarity for the CSMs, and validate the presented CSM, including the following: (1) identify primary risk drivers depending on potential pathways to sensitive receptors, which then might lead to other considerations siting and defining potential further assessment as well as lessen the effects of risk parameters; (2) consider potential modes of tracing impacts from anthropogenic infiltration using fluoride analysis;  (3) use major anion and cation chemistry to delineate waters, which would provide a reasonable means of classifying the different waters; and (4) utilize solid phase controls on water chemistry in assessing the likely flow paths for different groups of water.

Federal Facility Agreement Program Requirement Support, Former Naval Air Station Alameda, Alameda, CA, NAVFAC Southwest

The Adanta team will support the BRAC Program Management Office West, NAVFAC SW by executing the following tasks: (1) prepare monthly status reports and invoices and coordinate with the Navy RPM; (2) conduct required internal financial tracking, management of subcontracts and subcontractors, and assure that the project team meets all NAVFAC and Adanta Health and Safety requirements; (3) conduct regularly scheduled technical performance reviews; (4) maintain an electronic and hard copy mailing list to ensure communications are reaching the correct and interested parties; (5) update and maintain onsite and offsite information repositories; (6) produce and distribute the annual Site Management Plan (SMP); (7) assist the Navy in fulfilling its obligations and recommendations for community outreach as outlined in the Community Involvement Plan; (8) coordinate the logistics for the annual RAB/Community and RAB-only Tours; (9) support monthly BCT and bi-monthly RAB meetings; and (10) provide a GIS specialist with Alameda Point transfer database experience to provide maintenance and support. Additionally, there are options to continue supporting the above tasks using the same technical approach.


Contamination Investigation, Installation Restoration Program (IRP) Site 22, Naval Base San Diego, San Diego, CA, NAVFAC Southwest

Initially, Adanta focused on identifying sources of soil and groundwater contamination at the facility. Previous phases of work had not included an area-wide systematic project approach to determine soil and groundwater sampling locations and relate the results of those samplings to the overall contamination plume(s). Adanta reviewed historical base maps from the 1940’s, photogrammetrically reviewed historical aerial photographs using stereoscopes, and identified and reviewed other historical sources and documents. Numerous existing soil and groundwater contamination reports were also reviewed and analyzed, and key details that had not been previously identified were documented, allowing our scientists to draw detailed and accurate conclusions regarding the sources of the contamination to further support future activities on the project. Due to very positive results and feedback from the client, Adanta’s role was expanded dramatically to include writing, reviewing, analyzing, and formulating conclusions and recommendations, allowing our scientists to play a key role in determining the overall project direction, as well in its full execution, and an opportunity to interface with consultants that had done previous assessments, local oversight authority professionals, and NAVFAC staff. Adanta’s performance was met with high levels of approval, especially with regards to our deliverables, and level of responsiveness and flexibility in meeting requirements as they materialized.


Biological Monitoring during PCB hotspot removal, Hunter’s Point Naval Shipyard, San Francisco, CA, NAVFAC Southwest

Adanta has provided natural resource protection expertise for this project since January 2014. Gilbane is conducting PCB-containing soil hotspot removal at this site. Initially, Adanta completed a biological assessment, which included a survey of past biological reports and diversity databases and maps, and field surveys to observe the presence of endangered species at the site which could be impacted by site restoration activities. The USFWS was concerned that the restoration of a nearby wetland may have attracted a variety of endangered species to the area. Species of concern include the Clapper Rail, Burrowing Owl, and Salt Marsh Harvest Mouse. Based on observations and in-depth habitat surveys, it was determined that it is unlikely that endangered species will be found at the site or affected by the project. Protocol-level Clapper Rail surveys did not reveal evidence of Clapper Rails at the site. Adanta is conducting ongoing daily biological monitoring to ensure compliance with the project’s resource protection requirements.

Burrowing Owl and Nesting Bird Monitoring, Moffett Airfield, Mountain View, CA, NAVFAC Southwest

Adanta, Inc. is providing biological expertise during the renovation of historic Hangar 1 at Moffett Field, California. Renovation activities, including removal of PCBs, lead, and asbestos-containing hangar skin material, is occurring at the site. Burrowing owls are nesting around the hangar. The U.S. Department of Fish and Game lists the Burrowing Owl as a Species of Special Concern, which is threatened due to major habitat loss. The San Francisco Bay Area is one of four primary Burrowing Owl nesting areas in California. Monitoring will reduce the impact of construction activities on existing owl populations at the Site. In addition, the U.S. Department of Fish and Game has also requested that Adanta conduct nesting bird surveys to monitor nests and limit additional nest building inside the hangar. To this end, Adanta’s biologist is conducting additional weekly elevated surveys to inspect and evaluate suspected nest locations inside the hangar for Barn Swallows, Cliff Swallows, Common Ravens, Barn Owls, American Kestrels, Phoebes, and House Finches. Adanta has been able to identify additional animal species which have been active in and around the hangar so that the project team can develop the proper mitigation approaches. Both AMEC and NAVFAC have expressed their satisfaction with the personnel and level of expertise Adanta is providing on this project, including the weekly avian monitoring reports and biological recommendations. Overall, the project won the SAME San Diego Post Award of Excellence.

The newsletter is the ANG’s premiere medium for communicating and disseminating important information regarding environmental compliance, stewardship, and sustainability to ANG military personnel and their families, civilians, and contractors. They are electronically disseminated by the EPO during the first weeks of October, January, April and July. In addition to designing, editing, and producing draft and final newsletters, the EPO director occasionally requests that Adanta prepare articles on specific topics. Final versions of the newsletter are produced in PDF format.

Endangered and Invasive Plant Survey, Lake Mendocino, CA, USACE San Francisco

Adanta conducted a one-year survey of endangered and invasive plants at Lake Mendocino, near Ukiah, California. This floristic survey included vascular plants, aquatic plants, bryophytes, and lichens in the area surrounding Lake Mendocino of approximately 1600 acres, which is administered by the USACE. The purpose of the survey was to document occurrences of rare, threatened or endangered species, other special-status plants and vegetation communities, and invasive plants that could potentially threaten native plant populations. The project included a pre-field background search and literature review of all existing data pertaining to botanical resources within the area. This determined which special-status plant species had the potential to occur within the survey area, and where survey efforts should be focused. The field portion of the project included five sets of botanical surveys to capture the peak bloom season of the plants in the area. The location of each species was documented using a GPS system, and all species were photographed. In some cases, samples were collected. At the end of the project, a comprehensive report was compiled. One highlight of the project was that Adanta’s botanist discovered a Burke’s Goldfield, which had not been recorded in the area since the 1880’s.

Stormwater Best Management Practices Inspections, Common Mission Control Center, Beale AFB, Marysville, CA, Beale AFB Common Mission Control Center

Adanta performed environmental QC oversight services for the Mission Control Center project at Beale AFB located near Sacramento, California. The scope of work included 4 to 5 site visits focused on inspections of stormwater BMP’s. Adanta provided a CQC inspector, who was present onsite during environmental activities as required, and reported to the CQC System Manager. During each inspection, the inspector walked the project sites and evaluated environmental conditions as well as previously installed stormwater BMP’s, noted needs for corrective actions, and made recommendations as needed. The inspector also prepared daily reports including a written account of personnel onsite, features of work observed, photographs, and any noted deviations/corrective actions taken.
