LIRR Long Island City Freight Yard - In Situ Chemical Oxidation Remediation Project

Site Investigation and Characterization

D&B has performed site characterization and remediation services at a wide range of contaminated facilities and sites with projects ranging from relatively simplistic preliminary site assessments to complex site characterization studies and remedial investigation/feasibility studies (RI/FS). These projects have included:

  • Electrical substations
  • Electrical generation facilities
  • Petroleum storage and transfer facilities
  • Municipal, industrial and Construction & Demolition (C&D) landfills
  • Former Manufactured Gas Plants (MGPs)
  • Commercial and industrial dry cleaners
  • Aircraft manufacturing plants
  • Die and tool manufacturers
  • Railroad maintenance and fabrication facilities
  • Electro-plating facilities
  • Oil, solvent, metal and drum recycling facilities
  • Chemical storage and transfer facilities
  • Vehicle repair and printing shops
  • Outdoor shooting ranges
  • Steel mills and foundries
  • Heat treating and furniture manufacturing facilities
  • Dredge spoil disposal sites
  • Electronic components and computer chip manufacturing facilities

Extensive Experience

D&B’s experience in site characterization studies and remedial investigation includes numerous sites throughout New York State. Our highly trained, experienced staff includes geologists, hydrogeologists and environmental engineers. Our team has characterized a wide range of contaminants in complex geologic settings, including fractured bedrock aquifers in upstate New York, and Long Island’s sole source aquifer system.

D&B has also characterized the nature and extent of contaminants in a wide range of environmental media, including surface water, surface water sediment, soil vapor and indoor air. In addition to standard technologies such as groundwater monitoring wells, we have utilized a number of innovative site characterization technologies:

  • Rotosonic drilling
  • Cone penetrometer technology (CPT)
  • Environmental forensic analysis
  • Pre-packed/direct push well screens
  • Direct push membrane interface probes (MIP)
  • Videocone and fuel fluorescence detections (FFD)

Figure 3-2Field Investigations

D&B has extensive experience in conducting field investigations and remedial programs in highly urbanized areas such as New York City, as well as smaller cities located throughout New York, New Jersey and Connecticut. Through this experience, D&B has developed protocols and procedures specifically designed to address the unique aspects of investigating and remediating sites located in urban environments.


Our staff is highly experienced in defining contaminant source areas and tracking and mapping the associated groundwater plumes and their potential impacts to surface water, soil vapor and to the surrounding community. In addition to the collection of a wide range of environmental data, D&B develops conceptual models for each project based on the collected field and chemical data and our understanding of the site-specific hydrogeology to identify the likely fate and transport of the contaminants of concern and potential receptors. We also use sophisticated geochemical modeling and three dimensional (3D) computer models to help predict contaminant migration and to develop cost-effective remedial alternatives.

Data Management, Interpretation and Reporting

D&B manages all environmental data, including chemical and geologic, using the state-of-the-art EQuIS Environmental Data Management System (EQuIS), the standard database management system adopted for all projects overseen by the NYSDEC. Our staff is fully trained and experienced in the use of the EQuIS system, enabling us to prepare report graphics and tables in a standardized and cost-efficient manner.

In addition to conducting detailed remedial technology evaluation/pre-design studies necessary to select the most appropriate remedial strategy, we have substantial experience in the actual design of numerous remedial systems.
