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.
