Marion County Groundwater Wells Nitrate Map
Numerous lines of evidence indicate that existing elevated nitrate concentrations throughout much of the Floridan aquifer may be harmful to humans in addition to their noxious effects on the ecology of the springs.
The Environmental Protection Agency (EPA), on its' website states that "nitrate may cause problems if present in public or private water supplies in amounts greater than the drinking water standard set by EPA." The maximum contaminant level (MCL) is 10 milligrams per liter (mg/l). The same EPA website states that "infants below the age of six months who drink water containing nitrate in excess of the MCL could become seriously ill, and if untreated, may die."
