Cleanup Methods

Various technologies are used to clean up contaminated sediments. Rarely is one technology always best in every situation. Options can be used singly or in combination to clean up sediments. Remedial options most widely recognized by EPA guidance and other technical resources are:
  • Dredging sediments and disposing them in a confined facility such as a landfill
  • Capping sediments in place with clean sands or other clean materials to isolate them from the environment
  • Monitored Natural Recovery, which is a process of monitoring a water body's ability to clean itself up through natural processes
  • Treatment – including innovative technologies – where chemical or physical processes are used to stabilize or remove sediment chemicals or make them less toxic
