What the ground in Key Largo is like
The USDA soil survey rates mapped ground in Key Largo for septic drain-field suitability across roughly 12 square miles. About 100% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.
In Key Largo, the leading limit is flooding: parts of the mapped ground sit in areas that inundate from time to time. A drain field under water cannot treat or disperse effluent, and floodwater can lift untreated waste into the open. The survey flags that limit on about 100% of the rated ground here.
