Hidden threat: Global underground infrastructure vulnerable to sea-level rise - EurekAlert


As sea levels rise, coastal groundwater is lifted closer to the ground surface while also becoming saltier and more corrosive. A recent study by earth scientists at the University of Hawai‘i at Mānoa compiled research from experts worldwide showing that in cities where there are complex networks of buried and partially buried infrastructure, interaction with this shallower and saltier groundwater exacerbates corrosion and failure of critical systems such as sewer lines, roadways, and building foundations.
