About Subsurface

Soil contamination is often an issue that must be resolved for redevelopment and Brownfields projects.  Contaminated soils must be treated or removed to ensure that vapors do not enter buildings and cause health issues for future occupants and tenants. Likewise, contaminated groundwater must be monitored  to ensure health and safety of future occupants.

Examples of Soil Contamination:

  • Fuels, including gasoline and fuel oils
  • PCPs
  • Dry cleaning chemicals 
  • Creosote
  • Heavy metals – lead, mercury, cadmium
  • Polynuclear aromatic hydrocarbons (PAHs)
