WPI provides OM&M services at about 100 sites throughout the western United States. These range in size and complexity from simple vapor extraction/groundwater treatment systems addressing areas of about 1,000 square feet, to complex treatment systems designed to recover soil and groundwater contaminants from an area of 9,000 acres. Whether large or small, the OM&M Group has developed an organized approach that ensures system optimization and maximizes run time. Key components of this approach are:

  • Site Safety
  • Permitting and Permit Compliance
  • System Optimization and Balance
  • Data Collection and Reporting
  • Continued Research and Development

WPI equips each technician with all necessary monitoring, sampling, testing and repair equipment. This ensures that each arrives at the job site ready for any assignment and capable of dealing with changing conditions. Our capabilities include:
