Lakehurst Basewide Five-Year Review

Statutory Requirement for Five-Year Reviews

Under CERCLA § 121(c), if a remedial action results in hazardous substances or contaminants remaining at the site above levels that allow for unlimited use and unrestricted exposure, the remedial action must be reviewed every five years to assure that human health and the environment are being protected

21“WIN AS ONE”

Lakehurst BasewideFive-Year Review

The purpose of a five-year review is to determine whether the remedy implemented at a site is protective of human health and the environment

Three core questions:A. Is the remedy functioning as intended?B. Are the assumptions used when the remedy was selected still valid?C. Has any other information come to light that could call into question the

protectiveness of the remedy?

All Lakehurst active CERCLA sites with remedies in place included in this review

IMPACTS OF COVID ON PBR

Overall impacts of COVID on PBR progress have been minimal

• Contractor and government teams have continued to work effectively through telework and virtual meetings (like this one)

• JB MDL was closed for non-essential work between 18 March and 8 July Mission Essential letters were issued to Arcadis to ensure on-going remedial systems were

maintained and continued during that period New activities were restricted which stopped several sites moving forward as planned (soil

mixing at NW042, completion of buildout at TU003, new sampling activities etc.) BOMARC and MAG1 sites outside the fence were not impacted and significant progress was

made on those sites during this time period On-site work is now proceeding again

BOMARC Site Plan

• Two volatile organic compound (VOC) plumes impacted by TCE and DCE, originate from BOMARC.

• The OT016 plume extends onto Colliers Mill Refuge.

• The WP005 plume is largely contained within the site.

Treatment System

Air Sparge wells aligned to create treatment zones across plumes perpendicular to groundwater flow

Conveyance lines for compressed air

BOMARC – AS System Layout

BOMARC REMEDY Selected remedy

is Air Sparge (AS) of both plumes

Duration is expected to be greater than 50 years on-site (AF property), but off-site impacts are expected to be addressed within 10 years

DGR System Operation

• Groundwater extracted via four new extraction wells

• Treated using granular activated carbon

• Treated water is reinjected upgradient into existing wells to enhance contaminant flushing

Remedial Implementation

Exaction Well Installation: Four new wells installed in January 2020

Redevelopment of New/Existing Wells: Completed in May 2020

System Construction: July/August 2020

System Startup/Shakedown: Awaiting approval of the Remedial Design

System will operate seasonally (9 months a year: April through November)

Remedial goals anticipated to be met in 2035

completed but did not support this approach

• Third: Larger excavation in 2017 Residual LNAPL and groundwater

impacts remain and additional action is required
