Warming temperatures and increasing amounts of pollutants that blue-green algae feed on have produced algae blooms that have affected communities like Salem, Oregon and Toledo, Ohio. Now, both states require regular toxins testing in their drinking water sources.
More states will likely follow suit, because, as the climate warms, Harmful Algae Blooms (HABS) are becoming more prevalent across the country and around the world. Toxins from the blooms can cause respiratory illnesses, organ damage and even death. Since the mid-2000’s, it’s gotten worse, and the worst have happened in the last decade. Climate change is playing a part.
