| Use of ex situ or in situ technologies to remediate a site with contaminated groundwater relies on a thorough understanding of the site’s unique hydrogeological conditions. It also relies on an understanding of groundwater characteristics that may change under future climate scenarios. The changes should be considered throughout the site cleanup pipeline, from site assessment through long-term remedy maintenance. This fact sheet describes potential climate change impacts on groundwater, such as altered directions of groundwater flow or decreased infiltration, as well as potential impacts on cleanup remedies and associated remediation technologies. The fact sheet also describes how climate vulnerabilities are addressed at National Priorities Lists sites such as the Hunters Point Naval Shipyard Superfund site in California, Torch Lake Superfund site in Michigan, and Wyckoff Co./Eagle Harbor site in Washington. |
