Historical activities at a former lock manufacturing plant in New Jersey resulted in the contamination of soils with volatile organic compounds (VOCs) and groundwater affected by a dissolved phase VOC plume originating from an area containing Dense Non-Aqueous Phase Liquid (DNAPL).  Contamination extends to the fractured bedrock aquifer.  

Advanced GeoServices successfully completed the delineation of the 177-acre contamination plume in both the unconsolidated and the bedrock aquifers and designed an in-situ injection remedy for the treatment of the plume.  We designed and oversaw the installation of the vapor intrusion mitigation system on the Site building and surrounding properties.  We utilized Modeling and Risk Assessments to limit the investigation and remediation to the area and media in which there were impacted receptors.

Advanced GeoServices is experienced in providing multi-disciplinary engineering services in support of brownfield redevelopment.  Advanced GeoServices is providing geotechnical and environmental services on a waterfront property in Hudson County, NJ to deliver a pad-ready industrial project on highly compressible organic material with historic fill,  impacted groundwater, and a pre-existing cap (consisting of amended dredge material) at the site of a former chemical manufacturing facility.  Advanced GeoServices is designing a surcharging program with provisions for management of impacted groundwater  to assist the property owner with meeting an aggressive construction schedule for a project that will allow the end use developer to build out the project with a shallow foundation system.   Advanced GeoServices' engineering capabilities will allow the ground improvement program to reduce the overall building costs significantly by eliminating the need for deep foundations.  The project is being led by our Neptune, NJ office.  

Created a preliminary engineering design for permitting of the a waterfront redevelopment area located along the Delaware River, which included former petroleum industry sites that needed to be remediated, a marina, and an endangered species habitat which needed to be protected.

Advanced GeoServices managed the site design for this 605-unit mixed-use residential project on a 40-acre Brownfield site along the Delaware River.  This project involved complicated coordination with the permitting agencies due to the complexity of the proposed development and the pre-existing environmental constraints at the site.  Advanced GeoServices worked with PADEP, the US Corps of Engineers, Brownfield Action Committee, PennDOT, and the Bucks County Conservation District in order to obtain the required permits for construction.  The project was developed as a traditional neighborhood design with a 9-acre neighborhood park that runs along the entire river frontage, incorporating protected, restored, and created wetlands, preservation of significant trees, new pathway system, timber bridge, seating, and landscaping with native trees, shrubs, grasses, and groundcover.  Vapor intrusion mitigation systems were designed for the residential buildings.

Advanced GeoServices provided environmental services to the developer of a former agricultural lime quarry and processing facility.  This included providing construction oversight during the PA Act 2 closure of the site by the owner.  Advanced GeoServices assisted with the brownfields development by performing Phase I & II environmental investigations, hydrogeologic modeling of the impacts of groundwater filling the quarry and its effect on the adjacent exceptional quality stream and associated PADEP permitting for the quarry closure and the residual waste landfill grading modifications.  Advanced GeoServices also gained regulatory approval for the beneficial reuse of lime waste in the on-site residual waste landfill.  The beneficial reuse created significant cost savings for the client.

Client and municipality seek to remediate contaminated site and develop a 50-acre public park. The plan envisions protecting riparian areas and developing a park that is a gateway to the waterfront, offers environmental education and recreational opportunities. Potential improvements include a Nature Center Building, pathway system, boardwalk with observation platforms, fishing piers, bird blinds and interpretive signage highlighting the parks unique ecosystem. A large open lawn area is proposed on a hilltop to recreate an historic promontory offering dramatic panoramic  views and an area for informal activities and special events.

In order to consolidate its operations and expand its office space, the decision was made to relocate to the Philadelphia Navy Yard with all employees.  Since the site is being redeveloped, historic, man-made features such as existing utilities were encountered during construction that needed to be dealt with on a continual basis.  Advanced GeoServices provided construction phase services to act as a liaison between the client and the contractors and to keep the project running smoothly, including attending project meetings on site, observing field conditions, providing documents and information to facilitate the construction process, and responding to requests for information from the contractors.

Advanced GeoServices provided environmental investigation and design services for a 5-acre industrial tract being developed for mixed-use.  The project included the testing of the site building and over 30 residential properties surrounding the Site. Advanced GeoServices provided the vapor mitigation system design drawings and installation recommendations, and post installation testing and compliance reporting.  

A city block was redeveloped into a health and housing center as well as affordable housing units.  Our demolition approach included a Green Building strategy in consideration of the local economy.  Thanks to this approach, the project qualified for a Pennsylvania Housing Finance Agency Grant $720,000 and $3.3 to $3.5 million tax credit.  The city's Redevelopment Authority also allocated $400,000 in state funds for the project.  By combining our land planning/site design expertise with our environmental and geotechnical engineering skills, we were able to reduce the development costs and allow this affordable housing project to move forward.  The project developer won a 2006 Chester County Economic Development Council award for this project.

Advanced GeoServices is providing vapor intrusion and indoor air quality testing for a new residential development on a fast-track basis at a former industrial facility.  Passive mitigation systems are being installed as contingency measures.  On-demand testing is being performed as each new building unit is completed to demonstrate acceptable air quality using the passive systems or if the passive systems need to be converted to active systems.  

Advanced GeoServices was retained by a global diversified manufacturing and service company to understand the potential environmental issues at this recently closed facility, to refine the environmental reserve estimates, and to facilitate the property sale and re-use.  A strategic investigation approach was used to quickly remove the uncertainty associated with potential environmental impacts and risks.  This allowed the property to be sold within 2 years of its listing date for the original asking price.  A No Further Action approval was achieved within four years.
