Microcystins in Saint Johns River Estates Florida Water

Unhealthy Levels of Microcystins in the Water Supply of Saint Johns River Estates Florida Homes

Microcystins are toxins released by certain cyanobacteria, often called blue-green algae, that can get into drinking water when blooms occur. These contaminants aren’t the same as routine taste-and-odor problems and can be present even when water appears clear. Local homeowners in Saint Johns River Estates may learn about microcystins from utility notices, the St. Johns River Water Management District, or seasonal advisories; one frequently mentioned variant is microcystin-LR.

When microcystins are a potential issue, treating water at a single point for the whole house is the safest way to limit exposure across everyday uses. Cooking, making ice, rinsing produce, and brushing teeth all rely on tap water, so a solution at the main line protects showers, appliances, and kitchen taps alike. Because microcystins are dissolved contaminants, they won’t be removed effectively by sediment filters alone; a whole-house system gives consistent protection at every outlet in a Saint Johns River Estates home on the hard, Floridan aquifer–derived water common in our area.
