I'll add our issues on salt water intrusion in south Florida as well. Salt Water intrusion is a very big issue in the State of Florida, and one that much research has been done and is continued to be done. Here at Miami-Dade County Water and Sewer Department, we work with the US Geological Survey and our own Miami-Dade County Department of Environmental Resources Management to monitor the salt intrusion front in the Biscayne aquifer here in MD County, and are continually adding new monitoring stations as the front either has moved or where we have data gaps in the monitoring network. Here are some links to USGS publications and websites for our salt front monitoring program - https://pubs.er.usgs.gov/publication/sir20145025
We are in the process of updating the salt front for publication with the USGS, however our monitoring system is very robust and probably one of the most sophisticated in the world. We have integrated many different types of data (water quality, isotopes, geophysical logging, surface seismics, etc) into monitoring the salt front here. If anyone is interested in our monitoring network and data, we would be very happy to discuss and share.
We have a very strong groundwater modeling program here at Miami-Dade County, and work with the USGS and the South Florida Water Management District on modeling the salt front and how it will affect water resources here in south Florida. The model documentation and initial results can be found here:
We are also working with other counties in Southeast Florida through the Southeast Florida County Compact, as this is a regional issue, and not just a Miami-Dade County issue. The Compact has developed a Unified Sea Level Rise Projections for the region, and we are continuing to model using the Unified projections to assess salt front advancement in relation to SLR and climate change, and how we will need to respond as a utility to those changes.

In addition, Florida Department of Environmental Protection has put together a Salinity Network Workgroup for the State which includes FDEP, USGS, and many other agencies and utilities – Contact Rick Copeland, P.G. Ph.D.

Subject: SALTWATER INTRUSION INTO GROUNDWATER
I'm curious about saltwater intrusion into groundwater supplies. What are some good locations where this is happening? And what research has been done on this?
