A Screening Assessment of the Relative Vulnerability of Coastal Water Supplies to Salt Water Intrusion Caused By Sea Level Rise

Sea levels have risen from four to eight inches in the 20th century, and model projections suggest an additional rise of 8 to 15 inches is possible during the 21st century. Rising sea levels can increase the upstream extent of salt water influence in coastal aquifers. In coastal areas, drinking water treatment facilities may be vulnerable to sourcewater impairment caused by sea level rise and salt water intrusion.
