Challenges of maintaining fresh groundwater resources with rising sea levels Posted July 13, 2017 by WM. Scott Manahan, P.E. According to data from the Southeast Regional Climate Change Compact Unified Sea Level Rise Projection, sea levels in South Florida are anticipated to rise six to 12 inches by the year 2030. This is an issue not only in Southern Florida, but across coastal areas around the U.S. A challenge these areas face is to assess the nature and extent of the threat of saltwater intrusion into the coastal ecosystem and the public water supply considering population growth, increasing water supply demands and sea level rise. Saltwater intrusion into freshwater aquifers due to over-pumping has been a longtime concern among coastal water managers. This threat is exacerbated by rising sea levels along the coast. These concerns are being addressed by engineers, scientists and policy makers to ensure that coastal aquifers remain a viable source of freshwater for residents in South Florida. Following are strategies that have been implemented to manage Read More
