Well water toxics

Discovery of extensive groundwater contamination of wells with ethylene dibromide (EDB) in the early 1980's led to widespread public concern about the water quality of Florida's private potable wells.  DOH conducts investigation of wells or areas that may be at risk due to chemical release and to provide an alternative water source to a homeowner whose well is found to contain contaminants above the primary Maximum Contamination Level (MCL) or Health Advisory Level (HAL). These terms are explained here.

Limited Use Public Water Systems (public water systems which are not covered by the Safe Drinking Water Act), multi-family water systems, and private water systems.  Definitions for these systems and statutory authorization are found in section 381.0062 of the Florida Statutes. *Note: This page contains materials in the Portable Document Format (PDF).  The free Adobe Reader may be required to view these files.  Chapter 64E-8 of the Florida Administrative Code (pdf<1mb, opens in new window) establishes the rules to implement the statutes.  It includes setback standards for private water systems, construction standards for multi-family water systems, and construction and operation standards for limited use public water systems. Chapter 64E-8, and associated forms are also found here.
