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. The Florida Department of Health 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.

Delineated Contamination Areas

The Delineated Contamination Areas program is described in rules in Chapter 62-524 of the Florida Administrative Code, this rule defines the areas, helpful links, emails, addresses and contact phone numbers which apply to these areas, ways of identifying, or delineating, areas of groundwater contamination, email, phone list for the "Delineated Areas Program" and helpful links are found here.

Limited Use Public Water Systems

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. Chapter 64E-8 of the Florida Administrative Code 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.

Well Construction

The construction of drinking water supply wells is regulated by Chapter 62-532 of the Florida Administrative Code.
