Phase I Environmental Site Assessment in Mount Laurel, NJ
Mount Laurel anchors one of South Jersey's most active office, warehouse, and retail redevelopment markets, sitting where I-295, New Jersey Turnpike Exit 4, Route 38, and Route 73 converge in western Burlington County. Property owners, developers, contractors, municipalities, and counsel working across the South Jersey and Delaware Valley region rely on focused, locally informed environmental due diligence. Resource Renewal supports these projects through RCC's ASTM E1527-21 Phase I Environmental Site Assessment scope, layered with NJDEP-compliant Preliminary Assessments to deliver both federal and New Jersey innocent purchaser protections.
Resource Renewal connects three service tracks under one platform: ASTM E1527-21 Phase I ESAs and NJDEP Preliminary Assessments delivered by RCC; Phase II Site Investigations and Remedial Investigations when Recognized Environmental Conditions are identified; and full remediation and brownfield redevelopment delivered with our affiliated platform DSR. Project teams coordinate with the NJDEP Site Remediation Program and pursue site closure under LSRP oversight toward a Response Action Outcome (RAO).

Environmental Context in Mount Laurel and Burlington County
Industrial and Commercial Heritage
Mount Laurel Township was set off from Evesham Township in 1872 and stayed farmland, orchards, and greensand marl pits for most of its history. Centerton, on the Rancocas Creek, carried a wharf for steamboats running to Philadelphia from 1823 until roughly 1910, a bridge dating to 1834, and the nation's first phosphorus factory; Hartford and Masonville grew up along the railroad that arrived in 1867, and Masonville's Rancocas Woods drew trolley crowds to an amusement park on a lake dammed off Mason's Creek. Suburbanization began with Ramblewood in 1962 and never stopped, converting farm tracts into the Route 73 and Fellowship Road office corridor, the East Gate Corporate Center, and the warehouse belt around New Jersey Turnpike Exit 4. That sequence of farm and marl pit, small chemical works, then dense corridor commercial development is what Phase I ESA scoping in Mount Laurel has to reconstruct, alongside the service stations, strip-center dry cleaners, and fuel-dispensing sites that arrived with the highways.
Current Environmental Profile
NJDEP Site Remediation Program records list 38 active known contaminated sites inside Mount Laurel Township, 18 of them carrying an ongoing Classification Exception Area for groundwater. The profile is overwhelmingly corridor-commercial: petroleum hydrocarbons (TPH, BTEX) from underground storage tanks and service stations along Route 73, Route 38, and Church Road; chlorinated solvents (PCE, TCE) from strip-center dry cleaners at Ramblewood, Larchmont Plaza, and Larchmont Boulevard; and refined-product releases associated with the Colonial Pipeline right-of-way near Elbo Lane and the New Jersey Turnpike. Soil vapor intrusion screening is standard where office and residential use now sits over former commercial parcels, and PFAS is routinely added to Phase II scope near fire-training, plating, and fuel-handling areas. Historic pesticide and arsenic residues in orchard soils remain a live question on the township's remaining farm tracts.
Real Estate and Development Market
Mount Laurel is Burlington County's second-largest municipality by population and the anchor of the East Gate Corporate Center, the largest business park in southern New Jersey, sitting at the junction of I-295, the New Jersey Turnpike, Route 73, and Route 38. TD Bank's US headquarters at 4140 Church Road, the NFL Films campus on Sabol Way, and continuing office consolidation across Atrium Way and Horizon Way keep large-format office and flex assets trading. Retail redevelopment at East Gate Square, Centerton Square, Ramblewood, and Larchmont Plaza, together with last-mile warehouse demand off Turnpike Exit 4, drives steady Phase I ESA volume that spills into Moorestown, Maple Shade, Evesham, Hainesport, and Cherry Hill.
Local Regulators, Authorities, and Stakeholders
The NJDEP Southern Regional Office provides Site Remediation Program oversight for Burlington County. Routine touchpoints during Phase II and remedial action work include Burlington County planning and economic development offices, the Burlington County Soil Conservation District, the Mount Laurel Township Municipal Utilities Authority, and the township engineer. Sites draining to Parkers Creek, the South Branch Pennsauken Creek, or the Rancocas Creek often require coordination with the NJDEP Division of Water Quality, with added attention to Rancocas State Park frontage and floodplain constraints. Redevelopment of corridor parcels typically runs through the Mount Laurel Township planning board and zoning board of adjustment.
Why This Local Context Matters for Your Project
Local industrial history, the current contaminant profile, regulator office assignments, and real estate transaction velocity all feed directly into Phase I scoping decisions and downstream remediation planning. Mount Laurel sits in the same county as Resource Renewal's Mount Holly headquarters, so RCC crews already know the Southern Regional Office reviewers, the tank and dry-cleaner AOC profiles that dominate the Route 73 and Route 38 corridor, and how Burlington County review cycles actually run.

How Resource Renewal Serves Mount Laurel, NJ
Investigation & Compliance (RCC Track)
The ASTM E1527-21 Phase I ESA scope covers site reconnaissance, historical land use review, regulatory database searches, agency file reviews, and key personnel interviews. RCC layers the federal ASTM scope with an NJDEP-compliant Preliminary Assessment so projects carry both federal CERCLA and NJ ISRA innocent purchaser protections. When Recognized Environmental Conditions or Areas of Concern are identified, RCC moves directly into Phase II Site Investigation and, where warranted, Remedial Investigation — coordinating sampling plans, certified laboratory analysis, and data evaluation under NJDEP Site Remediation Program Tech Rules. Documentation is built for NJDEP review and LSRP certification.
Remediation & Redevelopment (DSR-Affiliated Track)
Remediation capabilities include in-situ chemical oxidation, bioremediation, soil vapor extraction, ex-situ excavation and disposal, groundwater pump-and-treat systems, permeable reactive barriers, sub-slab depressurization, and long-term operations, maintenance, and monitoring (OM&M). For owners exiting impaired property, the DSR platform provides brownfield acquisition, environmental liability transfer, and full redevelopment, applied across more than 100 brownfield sites in NJ, NY, PA, MA, and OH. The Mount Holly HQ at the Resource Renewal Business Park is itself a representative example of a former brownfield converted into productive operating real estate.
Frequently Asked Questions
-
Yes. Mount Laurel Township is served directly from Resource Renewal's headquarters at 10 Lippincott Lane in Mount Holly, a completed brownfield redevelopment project and the home base for RCC and DSR field crews working across Burlington County. Neighboring municipalities served from the same HQ include Moorestown, Maple Shade, Hainesport, Lumberton, Evesham, Medford, Willingboro, Westampton, Cinnaminson, and Cherry Hill.
-
A Phase I Environmental Site Assessment is a documented review of a property's current and historical use, performed under ASTM E1527-21, that identifies Recognized Environmental Conditions and Areas of Concern. Typical triggers include commercial real estate transactions, lender requirements, attorney due diligence, pre-redevelopment review, and refinancing. RCC pairs the ASTM Phase I ESA with an NJDEP-compliant Preliminary Assessment to provide combined federal CERCLA and NJ ISRA innocent purchaser protections. In Mount Laurel and Burlington County, the property types most likely to trigger Phase I work are office and flex buildings, warehouse and distribution facilities, automotive and fuel-dispensing sites, retail dry cleaners, and remaining agricultural parcels.
-
A typical Phase I ESA runs two to three weeks from authorization to draft delivery, depending on environmental database turnaround, depth of historical research, agency file review timing, and site access. RCC can accelerate timelines for time-sensitive transactions when scope and access permit. Layered NJDEP Preliminary Assessment work is coordinated within the same engagement. Under ASTM E1527-21, a Phase I ESA is valid for 180 days, with extensions of up to one year possible if specific components are refreshed.
-
When Recognized Environmental Conditions are identified, the natural next step is a Phase II Site Investigation: a defined sampling plan, certified laboratory analysis, and data evaluation against NJDEP standards. If contamination is confirmed, RCC develops a Remedial Investigation and a Remedial Action Workplan, pursuing a Response Action Outcome under LSRP oversight. For owners who prefer to exit the property rather than carry it through closure, DSR brownfield acquisition and environmental liability transfer are available as an alternative path.
-
DSR is Resource Renewal's brownfield redevelopment company, with experience across more than 100 brownfield sites in NJ, NY, PA, MA, and OH. DSR services include site evaluation, environmental liability transfer, and full redevelopment. DSR is a member of the EPA Landfill Methane Outreach Program and the Brownfield Coalition of the Northeast, and applies its Turn Brown to Green™ (TB2G™) model for landfill closure and beneficial reuse. EPA Brownfields Program grants and incentives may apply to qualifying Mount Holly and Burlington County sites.
-
Under the NJ Site Remediation Reform Act of 2009, contaminated sites are remediated under Licensed Site Remediation Professional oversight rather than direct NJDEP case management. The LSRP defines the technical approach, files key submissions, and issues a Response Action Outcome when site conditions meet applicable remediation standards. Typical sequencing is Preliminary Assessment, Site Investigation, Remedial Investigation, Remedial Action, and final RAO issuance. The RAO confirms regulatory closure and supports transactions, financing, and redevelopment.
-
Burlington County is New Jersey's largest county by land area and one of the most active warehouse and distribution development markets in the Northeast. The I-295 / NJ Turnpike Exit 4 / Route 38 corridor and proximity to the Port of Philadelphia have driven sustained conversion of agricultural and former industrial parcels into large-format warehouse, fulfillment, and last-mile distribution facilities. Each of those transactions typically triggers a Phase I ESA from lenders or institutional buyers. Volume has been particularly visible in Mount Laurel, Moorestown, Maple Shade, Evesham, and Cherry Hill.
-
The Resource Renewal Business Park at 10 Lippincott Lane is itself a brownfield redevelopment project that moved through the same investigation, remediation, regulatory closure, and reuse process RCC and DSR deliver for clients. It is a working demonstration that contaminated parcels can move from environmental liability to productive operating real estate when investigation, remediation, regulatory strategy, and redevelopment are executed by an integrated team. Prospective clients are welcome to walk the site as part of project scoping.
