Ultraviolet Light to be Used to Kill Tahoe Weeds

TAHOE CITY – Killing aquatic invasive weeds in Lake Tahoe with ultraviolet C light will be tried for the first time this summer.

The California Tahoe Conservancy board on March 16 agreed to spend $260,128 on the pilot project in South Lake Tahoe. The money was awarded to the Tahoe Resource Conservation District, which has been integral in working on ways to eradicate various invasive species from Lake Tahoe.

John J. Paoluccio of Inventive Resources Inc. has developed a system in which the plants are killed – almost like getting a lethal sun burn. The light damages the DNA and cell structure of the aquatic invasive weeds. This stops reproduction and eliminates the weed in a few days.
