Toxic Algae Incidents Across the World

Used from UNESCO/IOC article

We have found a lot of damage across the world  from toxic algae blooms and copper sulfate, which is the most commonly used water treatment by government bodies. This article is not meant to scare, but rather to inform our audience of the growing algae problem that is infecting our pets, children and the future of the world’s waterways.

Please let us know any incorrect information or an update we may have missed from the past few decades. Thanks for your interest in finding a better solution to the global water pollution crisis.

Help us Stop Toxic Algae Poisoning!


Used from UNESCO/IOC article

Government intervention is more often used for tracking and gathering data to clean the blooms rather than invest in finding strategies to stop the problem at the source.

For years, the EPA has practiced Nutrient Management Initiatives around the great lakes with $10 million recently appropriated to Lake Erie to reduce the open lake placement of dredge material with funds used to identify or develop alternate uses for this material as well as additional disposal locations.

We need solutions to the problem, not another way to reduce farmer fertilizer runoff. (this helps, but is not a long term solution)

Together we can reduce waste and use less harmful chemicals that are spread into lakes, or we can admit that as humans we will continue to have toxic waste regardless of how much money we throw into these initiatives.

Nualgi has innovated a cost effective natural solution that balances the water food chain and does not require any changes to farmers or citizens routines.
