Migration of contamination through the subsurface can be a challenge to delineate and remediate.  More than twenty years of experience in the field in cases involving petroleum hydrocarbons, chlorinated solvents, vapor migration in the subsurface, leachate migration from landfills, etc., ensures an expeditious site assessment or case oversight.  Getting it done right the first time is critical to attaining a swift solution to the problem.
