New technology uses ultrasonic waves to control harmful algal blooms

In 2019, the state recorded more than 70 suspected and 39 confirmed harmful algal blooms in New Jersey, up from in 2018

New Jersey’s lakes and ponds have taken a beating the last few years. Hot and sunny days mixed with stagnant water created a pesky algal bloom problem for the Department of Environmental Protection. Scientists are now deploying a new weapon in the fight — a high-tech system of ultrasonic frequencies blasting the bacteria and battling toxic blooms. Correspondent Leah Mishkin reports.
