Environmental Consulting :: Subsurface Investigations

Winefield & Associates, Inc. (W&A) evaluates soil and groundwater contamination using a myriad of hydrogeologic investigation tools. We determine the lateral and vertical extents of contamination for facilities ranging in size from 0.25 acre to 100 acres. W&A's subsurface investigation clients have included service station owners, refinery operators, solvent manufacturers, and municipalities conducting Brownfield redevelopment and management.

Typical investigation objectives include:

• Drilling soil borings and collecting physical samples for site-specific stratigraphic characterization
  
• Installing monitoring wells
  
• Collecting samples for chemical characterization
  
• Surveying monitoring well elevations and locations
  
• Estimating groundwater flow based on survey data
  
• Evaluating contaminant concentration distribution and migration potential
  

W&A also conducts:

• Phase I assessments
  
• Hydrogeologic computer modeling
