The phenomenon that can not be spoken in Florida continues as salt water intrusion moves inland

sewer water overflow
The densely populated megalopolis of South Florida is losing it's water wells as sea water intrudes into the Biscayne Aquifer. Salt water has already moved 6 miles inland in Broward County and is likely to continue to creep westward. Ninety percent of South Florida gets its drinking water from underground supplies, most from the Biscayne aquifer. This inland movement observed in Broward County is due to urban withdrawals from the Biscayne Aquifer, ocean water moving sideways into the aquifer and seepage of saltwater from surface sources.

Governor Scott, this is threatening the habitability of a region of close to 6 million of your fellow Floridians. Your inaction and hostility towards climate issues and sustainability now threatens funds and other aid from FEMA as they will not give money to any state that does not plan for climate change. Where is the disaster relief going to come from if not from Federal sources?

A report titled Climate Change AND Sea-Level Rise IN Florida notes the hellish calamity that will affect Florida's urban populations, economy, ecosystems and coasts.
What we know.
Florida‘s Biscayne Aquifer, the principal water supply to southeastern Florida and the Florida Keys, is recharged by rainfall and the freshwater Everglades. Surficial coastal aquifers are already experiencing saltwater intrusion. Rising sea level will increase the hydraulic backpressure on coastal aquifers, reduce groundwater flow toward the ocean, and cause the saltwater front to move inland, thus threatening to contaminate water-supply wells in coastal areas with seawater. In the low-lying southernmost Everglades, sea-level rise will cause brackish waters to encroach farther
northward.

The Pensacola Bay and St. Johns River watersheds and southern Florida from Palm Beach to Miami, the Florida Keys, Naples, and Fort Myers are especially vulnerable to saltwater intrusion into municipal freshwater supplies as sea levels rise (Dausman and Langevin, 2005; Freed et al., 2005; Murley et al., 2008).

The Comprehensive Everglades Restoration Plan’s main purpose is to increase freshwater flow to the southern Everglades. This will help offset the effect of sea-level rise and help preserve Everglades ecologies and southern Florida’s water supply (South Florida Water Management District, 2009a). The South Florida Water Management District already spends millions of dollars per year to prevent Miami’s Biscayne Aquifer from becoming brackish (Miller et al., 1989). Rising sea level will cause groundwater near the coast to become more saline and groundwater levels to increase.
