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?
This is a big problem in Florida, and there is a lot of research around it.
I've attached a college paper I wrote on the subject a while ago - it has some good references (I think).Hope it helps.
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.
