CORE Environmental Consultants, Inc. led all phases of investigation and remediation at a private redevelopment site under the New York State Department of Environmental Conservation (NYSDEC) Brownfield Cleanup Program (BCP). The site, formerly occupied by an industrial warehouse, was impacted by tetrachloroethylene (PCE) and trichloroethylene (TCE) in soil, groundwater, and sub-slab vapor.
CORE supported the project from BCP entry through regulatory closure, providing complete environmental services including investigation, vapor mitigation system design, remedial execution, and long-term monitoring and compliance reporting.
Remedial Investigation & Planning
CORE developed a Remedial Investigation Work Plan (RIWP) supported by a Health and Safety Plan (HASP), Community Air Monitoring Plan (CAMP), and Quality Assurance Project Plan (QAPP). Subsurface sampling confirmed significant VOC contamination beneath the former warehouse footprint.
Vapor Intrusion Mitigation
As an Interim Remedial Measure (IRM), CORE designed and oversaw the installation of a full-building Sub-Slab Depressurization System (SSDS). Design and performance details were submitted through a Design Analysis Report (DAR) reviewed by NYSDEC.
“CORE’s technical leadership, regulatory fluency, and long-term consistency made a complex brownfield site manageable—from initial investigation through system design and post-remedial care.”
Full-Site Remedial Action
The Remedial Work Plan (RWP) specified a combined remedy of Air Sparge and Soil Vapor Extraction (AS/SVE) paired with targeted in-situ groundwater treatment. The system prevents off-site migration of PCE/TCE and reduces residual source material.
CORE completed construction oversight and submitted the Final Engineering Report (FER) and Site Management Plan (SMP), leading to a Certificate of Completion (CoC) from NYSDEC.
Post-Remedial Monitoring
CORE continues to perform operation and maintenance (O&M) and groundwater sampling in compliance with the SMP to ensure long-term environmental control and regulatory adherence.
