Passage of the Resource Conservation and Recovery Act (RCRA) in 1976 signaled the beginning of an active regulatory program to manage hazardous waste.  Similarly, the 1980 passage of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), also known as Superfund, launched the clean-up of existing sites contaminated with hazardous waste.  Subsequent amendments have strengthened and added complexity to these regulations.  Although considerable progress has been made in the identification, study and remediation of hazardous waste sites, much remains to be accomplished.  Some of the typical services WLA can provide are listed below: 

  • Preliminary assessment
  • Remedial action
  • Remedial investigation
  • Waste minimization
  • Feasibility studies
  • Resource recovery
  • Remedial design
  • Construction administration
