Microcystins in Orlando Florida Water

Unhealthy Levels of Microcystins in the Water Supply of Orlando Florida Homes

Microcystins are toxins produced by certain cyanobacteria (often called blue-green algae) that can make their way into drinking water during algae blooms. Because these compounds differ from routine taste-and-odor problems, they can be present even when water appears clear at the tap. In Central Florida’s warm climate, seasonal conditions and heavy rains can increase algae and biofilm potential in source water and plumbing, so Orlando homeowners may learn about microcystins from utility advisories or local news. One frequently mentioned form is microcystin-LR.

When microcystins are a local concern, the aim is to lower exposure throughout the whole house—not only at the kitchen faucet. Everyday uses like cooking, making ice, rinsing produce, brushing teeth and filling humidifiers all involve the same supply, so treating only a single point-of-use leaves other taps vulnerable. Because microcystins are dissolved organic toxins, sediment-only filters won’t reliably remove them. A whole-house system gives consistent treatment to every shower, appliance and fixture in Orlando homes, including areas with moderate water hardness.
