Charter Boat Captains Help Monitor Lake Erie Water Quality


Monitoring the health of Lake Erie is no small task, and it can’t be done alone. That’s why Stone Lab works with private charter captains on the lake to help collect water samples and monitor the algae and toxin levels in the water.

What Are Harmful Algal Blooms?


Ohio Sea Grant is discussing harmful algal blooms and their impact on Lake Erie as part of an ongoing video series. In this video, we cover what harmful algal blooms are, what makes them harmful, when they typically occur, their impact throughout the lake and what you should know to be aware of a bloom.

This project was partially funded by a Great Lakes HABs Collaboratory grant.

The ability of household pitcher-style water purifiers to remove microcystins depends on filtration rate and activated carbon source


Toxic cyanobacterial blooms are a global threat to human health due to contamination of drinking
water. To ensure public safety, water treatment plants must have the capability to remove
cyanotoxins from water. Recently, however, there have been several instances when microcystins, a
common group of cyanotoxins, have been detected in tap water. This research investigated if
commercially available pitcher-style water purifiers were able to remove microcystins from water.
Microcystins were extracted from two naturally occurring blooms in Lake Erie, diluted to initial
concentrations ranging from 1 to 5 μg/L, and then subjected to three purifier types. Results showed
that the purifier with the fastest percolation rate (126 seconds/L) and a filter cartridge comprised
solely of coconut-based activated carbon removed 50% or less of the microcystins, while the purifier
with the slowest percolation rate (374 seconds/L) and a blend of activated carbon decreased
microcystins to below detectable levels (<0.10 μg/L) in all experiments. Thus, pitcher-style purifiers
with slow percolation rates and composed of a blend of active carbon can provide an additional layer
of protection against microcystins; however, it is recommended that consumers switch water
sources when cyanotoxins are confirmed to be in tap water.
