A large number of hazardous waste sites and concern over their potential impacts to human health and the environment has led to stringent environmental legislation.  The cleanup of contaminated waste sites is subject to cleanup levels that do not necessarily reflect actual risks to human health and the environment.  Consequently, these assessments may result in unnecessary remedial action that can lead to added costs for liable parties.  Effective, properly documented site-specific risk analyses often result in less stringent cleanup levels (per state and/or federal requirements) and, thereby, save the client critical time and resources associated with site cleanup.  Progress conducts hazardous waste assessment and cleanup services for sites under a variety of federal and state compliance programs.
