A presentation has been made to the Candlewood Lake Authority about technology that could control or prevent blue-green algae blooms. LG Sonics spoke with the CLA yesterday about ultrasonic pressure. Buoys that produce sound waves would be able to detect when the toxic blooms are about to form, cause the organism to sink and eventually die off because of a lack of sunlight.
Blue-green algae blooms closed several town parks on Candlewood this summer. The toxin can irritate skin, eyes and noses if people or animals come in contact with it. If swallowed, it can have other more serious effects.
The specially equipped buoys cost about $45,000 each, are powered by solar panels and have a 50 acre effective area.
