Site Investigation and Remediation

Site Investigations are a staple of our geoscience practice, and our comprehensive understanding of state and federal regulations serve our multi-sector client base well.  In a broader context, our expertise lies in multiple phases of investigative work, including hydrogeological investigations, soil and groundwater quality assessments, conceptual site model development, sensitive receptor surveys, vapor intrusion, aquifer testing and analysis, and the collection of environmental samples to support the cleanup and closure of contaminated properties.  With an extensive range of technical skills, our team includes specialists in geology, hydrology, hydrogeology, fate and transport of contaminants, chemistry, risk assessment, wetlands science, site/civil and geotechnical engineering, geographic information systems (GIS), and the compilation of data for reporting and data upload purposes.

Our experience doesn’t end with the investigative phase of the project.  The Wilcox & Barton, Inc. team of Professional Engineers and Professional Geologists can also prepare remedial action plans to evaluate in situ and ex situ remedial technologies at a variety of cleanup sites, including home heating oil releases, petroleum fuel releases from above and underground storage tank systems, surface spills of petroleum products, and ongoing releases of hazardous and non-hazardous chemicals at current and former industrial sites.

Remedial designs by Wilcox & Barton, Inc. have included the following:

  • Groundwater pump and treat systems
  • Active and passive light non-aqueous phase liquid (LNAPL) recovery systems
  • Bioremediation and in situ chemical oxidation
  • Air-sparging (AS) and soil-vapor extraction (SVE) systems
  • Soil excavation and treatment, and
  • Perozone and oxygen injection systems

Preparation of these plans have included initial screening, detailed evaluations, and selection of preferred alternative(s) while considering effectiveness, reliability, implementability, costs, risks, benefits, timeliness, and feasibility of achieving cleanup goals.
