Frey Engineering personnel have provided engineering management, design, ground water investigation, and construction management services for a wastewater treatment plant, ground water recovery system, and residential treatment systems to control the migration of a chlorinated solvent ground water plume in the overburden and fractured bedrock at this landfill.  Frey has prepared a remedy evaluation report, ground water remedy redesign drawings and construction specifications, revisions to the long term monitoring program, a Soil Erosion and Sediment Control Plan, and an Interim Remedial Action Report.  Frey Engineering currently provides ground water monitoring reports for evaluating hydraulic capture of the chlorinated solvent plume and long-term trends analysis. 

Frey Engineering performed a geotechnical investigation and preliminary site planning to a frozen foods distributor for development of a 19-acre undeveloped area of the Ventron/Velsicol Superfund site following the completion of remedial actions involving removal of principal threat soils and capping. The property is impacted with elemental mercury from past operations of a former mercury recycling facility.  Frey Engineering performed a due diligence site investigation that focused on the geotechnical parameters of the subsurface for evaluating the type of foundation system that would be required given the completed remedial action and the poor bearing capacity of the soils.  Following the geotechnical investigation, Frey Engineering was retained to work with the site developer to prepare a Site Plan that would integrate the site remedy with the proposed site development plan.  Frey developed an approach to the building foundations that included dynamic compaction, preloading, and the installation of wick drains. Frey Engineering also was retained to review and determine the federal, state, and municipal permits that would be required to construct the distribution center.  Frey prepared a summary document of the permits that would be needed and their impact on the site construction. The permit review included: 1) wetlands, 2) riparian zone, 3) floodplain, 4) Hackensack-Meadowlands District, 5) stream encroachment, and 6) construction in an airport flight landing/take off zone.

Frey Engineering provided design and construction management services for the construction of an innovative wastewater treatment plant in western New Jersey.   Frey designed the treatment plant to have an 80% recycle rate, which was permitted to have multiple reuse pathways for the effluent including flush water, landscape irrigation and disposal trench.  This was the first time in New Jersey that such a use was allowed.  Frey personnel tasks included a ground water investigation (including aquifer tests), preparation of NJPDES Discharge to Groundwater permit, amendment to the existing regional Water Quality Management Plan (i.e. Delaware Basin Commission), soil erosion control plans (multiple), preparation of 30%, 60%, and 100% designs along with construction specifications.  Frey worked with multiple department sections within the NJDEP in obtaining the NJPDES permit and Treatment Works Approval.  Frey Engineering has also provided construction management for the entire complex, which includes buildings with a square footage of 450,000 square feet, a fire protection system (300,000 gallon fire water tank and diesel fire pump system), the WWTP, and all site improvements.

Frey Engineering was retained to evaluate and repair a series of malfunctioning septic disposal beds at a seventy-bed nursing home, with plans to expand their central New Jersey facility.  Frey personnel investigated and performed field repairs to eliminate the source of the malfunctions and provided guidance and oversight to bring the pump tank systems back to a state of good repair. Frey performed a soil investigation to identify suitable new disposal areas.  Due to site geologic limitations, the facility will require an on-site private wastewater treatment plant (WWTP) possibly using advanced recycling technology to achieve their expansion goals.  Ongoing Frey personnel tasks include a ground water investigation (including aquifer tests), preparation of NJPDES Discharge to Groundwater permit application, amendment to the existing regional Water Quality Management Plan, soil erosion control plans, and preparation of 30%, 60%, and 100% designs along with construction specifications.
