Services
Site Investigation and Environmental Remediation
HK Engineering & Geology provides site investigation and environmental remediation services for a wide range of commercial, industrial, and redevelopment projects. Our experienced team partners closely with clients to deliver cost-effective environmental engineering solutions for complex soil and groundwater remediation challenges.
Soil remediation services may include excavation, transportation, and disposal of contaminated soils; in-situ soil remediation; and the implementation of engineering and administrative controls, or a customized combination of these approaches. Groundwater remediation solutions may include in-situ treatment technologies such as air sparging, chemical reduction, and other proven remediation methods tailored to address site-specific conditions and regulatory requirements.
Brownfield Redevelopment and NYC E-Designation
HK Engineering & Geology provides comprehensive environmental consulting services for brownfield redevelopment and NYC E-Designation sites, supporting property owners, developers, and project teams through every phase of the redevelopment process. Our experienced professionals deliver practical, solutions-driven guidance beginning with environmental site assessment and detailed site characterization to evaluate existing conditions and regulatory requirements.
We continue to support projects through remediation planning, agency coordination, and construction-phase oversight, guiding projects toward successful site closure and regulatory approval while helping clients manage risk, control costs, and maintain project schedules.
Soil and Groundwater Vapor Intrusion
Vapor intrusion occurs when volatile chemicals from contaminated soil or groundwater migrate upward as vapors through subsurface soils and enter the indoor air of overlying buildings, potentially creating indoor air quality (IAQ) concerns and health risks for occupants.
To evaluate vapor intrusion conditions, soil gas sampling and indoor air monitoring are performed to identify the presence and concentration of volatile organic compounds (VOCs) and determine whether mitigation or remedial measures are required. HK Engineering & Geology provides vapor intrusion assessment, monitoring, and regulatory support to help property owners, developers, and stakeholders achieve environmental compliance.
UST Decommissioning and Compliance
HK Engineering & Geology provides experienced and reliable Underground Storage Tank (UST) decommissioning services for commercial and industrial sites. UST decommissioning involves the proper location, excavation, removal, and disposal of underground storage tanks in accordance with applicable regulatory requirements.
Our approach prioritizes safe handling, environmental protection, and thorough documentation, including required notifications, sampling, and recordkeeping. When performed incorrectly, UST decommissioning can pose significant safety, environmental, and regulatory risks. Our experienced team of professionals manage the process from start to finish, helping clients reduce liability, control costs, and achieve regulatory compliance.
