Lake Guard Blue was dispersed in Chippewa Lake and restored the lake’s ecological balance.

Israel-based cleantech company, BlueGreen Water Technologies Ltd., announces the success of cleaning toxic algae blooms with their product, Lake Guard Blue.

BlueGreen Water Technologies Ltd., an Israel-based cleantech company, announced the successful cleanup treatment against harmful algae blooms detected in Ohio’s Chippewa Lake, using its proprietary EPA-approved product, Lake Guard Blue. A short and simple application resulted in the collapse of the toxic cyanobacteria species that contaminated Chippewa Lake and in the restoration of its ecological balance.

Tests were conducted in the lake before, during and after the treatment in order to ensure that Chippewa Lake’s algae problem was fully addressed. This was the first full-scale deployment of BlueGreen’s product in the United States. The product is also in commercial use in Israel, China and South Africa.

Harmful algae are photosynthetic microorganisms that can be found in almost all bodies of water. Their toxins have been known to cause poisoning in animals and humans and severely disrupt the ecosystem. The EPA has declared harmful algae bloom as “a major environmental problem in all 50 states. They can have severe impact on human health, aquatic ecosystems and the economy.” EPA also warns that “algae blooms can be toxic. Keep people and pets away from water that is green, scummy or smells bad.”

This summer in Michigan, several dogs died after swimming in ponds with harmful algae blooms. According to the organization Sea Grant Michigan, these harmful blooms are commonly found in shallow, still bodies of water such as small lakes and ponds. The bacteria is also common in lakes with fertilizer runoff and warm water temperatures. However, blooms can also be found in parts of Lake St. Clair, Lake Michigan, Lake Huron and Lake Erie, the research organization added.

The World Health Organization (WHO) also publishes clear warning instructions: “People are mainly exposed to cyanobacterial toxins by drinking or bathing in contaminated water. Surface scums, where they occur, represent a specific hazard to human health because of their particularly high toxin contact. Contact, especially by children, should be avoided.”

Humans are affected with a range of symptoms including skin irritation, stomach cramps, vomiting, nausea, diarrhea, fever, sore throat, headache, muscle and joint pain, blisters of the mouth and liver damage. Swimmers in water containing cyanobacterial toxins may suffer allergic reactions, such as asthma, eye irritation, rashes and blisters around the mouth and nose. Animals, birds and fish can also be poisoned by high levels of toxin-producing cyanobacteria.

“Water is the essence of life and a basic human right,” said Eyal Harel, CEO of BlueGreen Water Technology. “Our technology empowers communities all over the world to reclaim their water resources and prevent harmful algae blooms by taking action swiftly and economically.”

According to Dr. Moshe Harel, chief technology officer of BlueGreen, the product is designed to float and slow-release its active ingredient. In Ohio, the product was dispersed in the lake from the back of a boat.
