More worrisome, blooms of cyanobacteria are becoming increasingly common, fueling fears that their toxic by - product may be quietly fomenting an upsurge in ALS — and possibly other neurological disorders like Alzheimer's disease and Parkinson's as well.

Lake Erie has become increasingly susceptible to large blooms of toxin - producing cyanobacteria since 2002, potentially complicating efforts to rein in the problem in the wake of this year's Toledo drinking water crisis, according to a new study led by University of Michigan researchers.

Since the detection of the toxin microcystin left nearly half a million Ohio and Michigan residents without drinking water for several days in early August, discussions of ways to prevent a recurrence have largely focused on the need to reduce the amount of phosphorus fertilizer that washes off croplands and flows into western Lake Erie to trigger harmful cyanobacteria blooms.

Other potential explanations for the reported trend in bloom susceptibility are increasingly calm summer weather conditions, which can also promote cyanobacteria dominance, and a growing reservoir of Microcystis seed colonies at the bottom of Lake Erie.

In August 2015 a thick bloom of algae known as Microcystis cyanobacteria re-appeared in Lake Atitlan; the first major occurrence was in 2009.
