DESCRIPTION:Groundwater Resilience Under Environmental and Human Pressures:
  From PFAS Contamination to Post-Hurricane Recovery Groundwater systems ar
 e increasingly threatened by the combined effects of human activities, cli
 mate variability, and extreme events. This presentation examines two compl
 ementary research efforts focused on groundwater contamination and aquifer
  recovery under different environmental and climatic conditions. The first
  project investigates the long-term behavior of per- and polyfluoroalkyl s
 ubstances (PFAS) released from historical firefighting activities in Killi
 ngworth, Connecticut. Through field characterization, laboratory adsorptio
 n experiments, and numerical modeling, the study evaluates PFAS retention 
 in the vadose zone, leaching to groundwater, and the factors controlling c
 ontaminant persistence and plume evolution under changing precipitation an
 d pumping conditions. The second project examines the recovery of groundwa
 ter resources on Grand Bahama following saltwater intrusion associated wit
 h Hurricane Dorian. Field observations, infiltration experiments, and grou
 ndwater flow and salt transport modeling are being used to assess the hydr
 ologic controls on aquifer recovery. The project further integrates social
 -science methods to investigate how post-disaster decisions, stakeholder r
 elationships, and community pressures influence long-term water-resource r
 ecovery. Together, these projects demonstrate the importance of integratin
 g field data, experimental methods, numerical modeling, and stakeholder kn
 owledge to understand groundwater vulnerability and improve resilience. Th
 e findings contribute to improved prediction of contaminant movement and a
 quifer recovery and support the development of scientifically informed and
  locally appropriate strategies for groundwater management under changing 
 environmental and societal conditions.\nEvent page: https://www.umassd.edu
