PCB Sampling and Analysis

CORE Environmental Consultants provides certified PCB (Polychlorinated Biphenyl) sampling and analysis for buildings and sites where hazardous building materials may be disturbed or require disposal. We identify and quantify materials containing PCBs in accordance with U.S. Environmental Protection Agency (EPA) and New York State guidance, helping clients plan safe removals, avoid regulatory violations, and meet project milestones.

PCBs, once widely used in building sealants, paints, caulks, and electrical components, are now classified as toxic substances. Improper handling or disposal of PCB-containing materials can result in costly delays, environmental liability, or regulatory enforcement.

CORE’s investigations are structured to deliver clear, defensible results and support downstream abatement, remediation, or disposal planning.

Where Are PCBs Found?

Although banned from most U.S. manufacturing after 1979, PCBs are still present in many commercial, institutional, and multi-family buildings constructed between the 1950s and 1970s. Common materials that may contain PCBs include:

• Caulks and sealants used in window glazing, expansion joints, masonry gaps, and curtain wall systems
• Paints and floor finishes
• Fluorescent light ballasts and transformers
• Roofing materials and mastics
• Concrete and porous substrates adjacent to contaminated materials

PCB-containing materials are typically uncovered during renovation, demolition, window replacement, façade upgrades, or hazardous materials surveys.

When Is PCB Sampling Required?

PCB sampling may be required or recommended under the following scenarios:

• Pre-renovation or demolition of buildings constructed before 1980
• Environmental due diligence or hazardous materials inventories
• Waste classification and disposal planning (TSCA vs non-TSCA)
• Planning for regulatory filings or remediation activities
• To fulfill the requirements of EPA, NYSDEC, or local environmental agencies
• In support of Brownfield Cleanup Program or site redevelopment

Failing to identify and properly classify PCB-containing materials can lead to improper disposal, unpermitted releases, or work stoppages.

Our PCB Sampling & Analysis Process

1. Project Review & Sampling Plan

Every project begins with a review of the building age, renovation history, and construction materials. We assess architectural drawings and conduct a site walkthrough to identify potential PCB-bearing materials based on use, location, and vintage.

A tailored sampling plan is created that defines:

• Sample types (bulk solids, wipes, liquids, etc.)
• Quantity and distribution based on homogeneous material groupings
• Sampling methods and safety protocols
• Applicable thresholds for regulatory classification

We prioritize areas where PCB use was historically common—such as exterior caulking, below-grade sealants, and indoor coatings.

2. Bulk Sample Collection

CORE’s field staff collects representative bulk samples using non-destructive or destructive techniques, depending on accessibility and client constraints. Common bulk sample materials include:

• Window and expansion joint caulks
• Concrete and brick in contact with PCB-containing sealants
• Interior and exterior paint layers
• Roofing membranes and adhesives
• Contaminated substrate materials

Each sample is documented with photos, location notes, and chain-of-custody procedures to ensure defensibility.

All samples are handled in accordance with EPA PCB Spill Cleanup Policy and OSHA HAZCOM protocols, minimizing risks to workers and occupants.

3. Laboratory Analysis

Samples are submitted to an EPA SW-846 certified laboratory for analysis using EPA Method 8082A (Gas Chromatography). The analysis determines:

• Total PCB concentration (expressed in mg/kg for solids or mg/L for liquids)
• Whether the material meets or exceeds the 50 ppm TSCA threshold
• Classification as TSCA-regulated or non-TSCA regulated waste
• Suitability for specific disposal facilities or remedial actions

Where needed, additional sample preparation methods (e.g., Soxhlet extraction or acid digestion) are used for complex matrices.

4. Documentation & Reporting

After analysis, CORE prepares a detailed report that includes:

• Sample locations and descriptions
• Annotated site plans or building elevations
• Laboratory certificates and detection summaries
• Regulatory interpretation (TSCA classification, spill or cleanup applicability)
• Recommendations for:
  • Abatement or encapsulation
  • Disposal (hazardous vs solid waste)
  • Further delineation if necessary

Our reporting is structured for submission to design teams, environmental managers, permitting authorities, and regulatory agencies.
