Septic & well water services in Monroe County, FL

Southernmost Florida county encompassing the Florida Keys, a chain of ancient coral reef limestone islands with almost no soil cover and a water table at or near the surface. Conventional septic systems are being phased out and replaced with advanced wastewater treatment due to direct contamination of nearshore waters and coral reef ecosystems. Wells are impractical on most Keys due to saltwater intrusion, with the Florida Keys Aqueduct providing freshwater from the mainland.
