New Jersey’s environmental regulatory environment is among the most stringent in the United States, and the state’s industrial and urban density creates a concentrated, technically complex geomembrane liner market. New Jersey has the highest per-capita density of PFAS-impacted sites of any state in the country, an industrial corridor in the northeastern part of the state that drives ongoing secondary containment demand, a legacy of Superfund and brownfield sites requiring engineered containment, and coastal infrastructure that must be designed for resilience and storm surge exposure. ICS brings the liner installation expertise, CQA documentation capability, and material range to serve New Jersey engineers, EPC contractors, environmental consultants, and facility managers operating under NJDEP’s Site Remediation Program and solid waste regulations.
PFAS Remediation and Containment Liner Systems
New Jersey has established some of the lowest PFAS maximum contaminant levels (MCLs) in the nation — 14 ppt for PFOA and 13 ppt for PFOS — creating remediation obligations at hundreds of sites statewide. PFAS-impacted sites include former manufacturing facilities, fire training areas, military installations, and landfills that accepted AFFF-contaminated waste. ICS installs geomembrane liner systems for PFAS containment applications, including low-permeability caps over contaminated soil and fill, liner-lined leachate collection ponds, and secondary containment upgrades at facilities handling PFAS-containing materials. HDPE is the primary liner material for PFAS applications due to its documented chemical resistance to PFOA and PFOS compounds at the concentrations found at most New Jersey sites.
NJDEP’s Site Remediation Program (SRP) governs cleanup and containment at most PFAS sites. Licensed Site Remediation Professionals (LSRPs) prepare Remedial Action Work Plans (RAWPs) that specify liner system requirements. ICS works with LSRPs, design engineers, and RAO contractors to deliver liner installation that meets RAWP specifications and supports NJDEP case closure.
Industrial Secondary Containment — Northeastern New Jersey Industrial Corridor
The northeastern New Jersey industrial corridor — stretching through Hudson, Essex, Bergen, and Union counties — hosts refineries, chemical processing plants, pharmaceutical manufacturers, and intermodal freight facilities with significant above-ground storage tank (AST) inventories. EPA SPCC regulations (40 CFR Part 112) and NJDEP requirements mandate secondary containment for petroleum and hazardous chemical storage. ICS installs secondary containment liner systems using HDPE, PVC, and XR-5 geomembranes selected for compatibility with the specific chemicals stored at each facility. XR-5 is frequently specified for applications involving aggressive solvents or aromatic hydrocarbons where standard HDPE does not provide adequate chemical resistance. ICS provides liner installation within existing bermed containment structures and in new containment pad construction, with close coordination with facility operations to minimize downtime.
Superfund Site Remediation Liner Systems
New Jersey has one of the largest Superfund site inventories of any state, including sites in the Raritan Bay area, the Meadowlands, and the industrial waterfront of Newark and Bayonne. Superfund remedial designs at New Jersey sites frequently incorporate engineered caps with HDPE or composite liner barrier layers, subsurface containment barriers, and liner-lined collection systems for contaminated groundwater or leachate. ICS provides specialty geomembrane installation services that fit within larger Superfund remediation contracts, delivering liner installation, field fabrication, and CQA-documented welding within the constraints of active remediation sites. NJDEP oversight during Superfund construction is rigorous, and ICS’s CQA documentation approach is designed to support NJDEP inspection requirements and EPA post-construction review.
Municipal Solid Waste Landfill Liner and Cap Systems
New Jersey solid waste regulations at N.J.A.C. 7:26 govern liner system requirements for municipal solid waste landfills and transfer stations. Landfill operators in New Jersey face a compressed permitting environment and strict post-closure care requirements that make CQA documentation quality critical to avoiding regulatory complications. ICS installs composite bottom liner systems and final cap systems for New Jersey MSW landfills, and provides CQA documentation packages structured to satisfy NJDEP’s technical requirements under N.J.A.C. 7:26. Landfill liner work in New Jersey often involves coordination with leachate recirculation systems and gas collection infrastructure — ICS’s liner installation sequencing accounts for these subsystem interfaces.
Coastal Resilience and Stormwater Infrastructure
New Jersey’s coastal geography and post-Sandy infrastructure investment have generated liner demand in stormwater detention basins, coastal retention ponds, and resilience infrastructure along the barrier islands and coastal plain. Stormwater management pond liners prevent infiltration of nutrient-laden or contaminated stormwater into shallow groundwater, and are required by NJDEP NPDES stormwater permits at many commercial and industrial sites. ICS installs HDPE and LLDPE pond liner systems for stormwater and coastal resilience applications, including sites with high water tables and difficult subgrade conditions common to New Jersey’s coastal plain geology.

Frequently Asked Questions — Geomembrane Liner Installation in New Jersey
What NJDEP regulations govern geomembrane liner systems at New Jersey remediation sites?
Most New Jersey remediation sites — including PFAS sites, brownfields, and Superfund operable units — are governed by NJDEP’s Site Remediation Program (SRP) under the Site Remediation Reform Act (SRRA). Liner systems are typically specified in a Remedial Action Work Plan (RAWP) prepared by a Licensed Site Remediation Professional (LSRP). Landfill liner systems are additionally governed by N.J.A.C. 7:26 (solid waste rules). ICS works directly with LSRPs and project design engineers to ensure liner installation meets the specific requirements of each regulatory framework.
What liner material does ICS recommend for PFAS containment in New Jersey?
HDPE (high-density polyethylene) is the standard liner material for PFAS containment applications, supported by chemical resistance data showing low permeation rates for PFOA and PFOS at typical environmental concentrations. For applications with very high PFAS concentrations or where PFAS precursors are present, some engineers specify a composite liner with a GCL to provide additional redundancy. ICS can assist the design engineer in evaluating liner options based on site-specific contaminant concentrations and regulatory requirements.
Can ICS install liner systems inside existing berm containment structures at operating industrial facilities?
Yes. ICS regularly installs secondary containment liner systems within existing bermed structures at operating industrial facilities, including tank farms, chemical storage areas, and loading areas. These installations require careful coordination with facility operations to work around active equipment, minimize downtime, and maintain secondary containment integrity during the installation window. ICS provides field fabrication of custom-sized liner panels to fit the specific geometry of each containment structure, including penetrations, sumps, and irregular corners.
Does NJDEP require CQA documentation for geomembrane liner installation at Superfund sites?
Yes. NJDEP oversight of Superfund remedial construction — including liner installation — requires CQA documentation that demonstrates the liner system was installed in accordance with the approved remedial design. This typically includes material conformance data, weld testing records, panel layout documentation, and a final CQA report. ICS provides complete CQA documentation packages structured to meet NJDEP and EPA Superfund construction completion requirements.
How does ICS handle high water table conditions common at New Jersey coastal sites?
High water table conditions present installation challenges including subgrade saturation, hydrostatic uplift on installed liner during construction, and difficulty achieving adequate soil compaction for liner support. ICS addresses these conditions through pre-installation dewatering planning, ballasting of installed liner panels during construction, and coordination with the earthwork contractor on subgrade preparation and drainage. Liner anchorage design accounts for hydrostatic uplift forces to prevent liner flotation during construction and prior to filling the impoundment.
