Emergency Planning & Response

Weston has earned a reputation for providing exceptional emergency preparedness, planning, and loss prevention services related to counter-terrorism planning as well as in response to catastrophic and environmentally sensitive events.

We have completed more than 1,180 emergency responses and more than 50 multiagency exercises and drills at the federal, state, and local levels under current and recently completed Superfund Technical Assessment and Response Team (START) contracts across all 10 Environmental Protection Agency (EPA) regions. Our expertise, which spans all types and magnitudes of time-critical responses, is backed by our proven ability to deploy over 400 responders in a short period of time to provide EPA with 24/7/365 rapid response support. We are proud to have been part of EPA’s largest responses, including the 9/11 World Trade Center, Capitol Anthrax, Columbia Shuttle Recovery, Deepwater Horizon, Hurricanes Katrina and Irene, and Superstorm Sandy.

Our wide range of emergency preparedness services includes:

  • Contingency Planning
  • Chemical Emergency Planning and Prevention, including real-time chemical agent monitoring

Water Quality

Weston has been recognized for our ability to provide integrated solutions to address the supply, storage, distribution, quality, restoration, and protection of water resources. From creating tablet-based, regulatory-compliant stormwater planning programs to providing a comprehensive $145M polychlorinated biphenyl (PCB) remediation and ecological restoration for the U.S. Army Corps of Engineers and Environmental Protection Agency (EPA), Weston water solutions yield savings and efficiencies.

With extensive expertise serving a broad range of agencies, including EPA, the U.S. Department of Interior, and the National Oceanic and Atmospheric Administration as well as state and local environmental and water management boards and utilities, Weston has addressed our clients’ most challenging water resource needs.

Our services include:

  • Water Resource Modeling
  • Flood and Watershed Management Studies
  • National Environmental Policy Act (NEPA) Compliance
  • Aquatic Toxicology
  • Hydrologic and Hydraulic Modeling
  • Environmental Sampling
  • Testing and Analyses, including sediment characterization; water quality; sediment transport modeling; and wetland enhancement, restoration, and creation

Munitions Response

Weston safely and successfully solves Munitions and Explosives of Concern (MEC), Chemical Warfare Materiel (CWM), and other high-hazard challenges for our clients. Our personnel are trained and highly experienced at addressing sites involving explosives, unexploded ordnance (UXO), chemical weapons, biological hazards, toxic agents, and radioactive materials.

Safety is paramount to our success in virtually every service we provide, but within this area, it is perhaps even more critical. That said, Weston’s Experience Modification rate (EMR) is consistently well under the industry norm, and our Occupational Safety and Health Administration (OSHA) recordable rate is less than half the industry average.

Innovation is key as well. Employing our Munitions Response solutions, we have saved our clients time and money by quickly and accurately identifying buried or concealed hazards using complex technologies such as electromagnetic and infrared sensors, ground-penetrating radar, remote sampling, magnetometry, advanced geophysical detection, and custom robotic solutions.
