The Twin Lakes Village Board approved spending up to $6,000 for Eurasian watermilfoil treatment this summer on Lakes Mary and Elizabeth.
Marine Biochemists of Germantown will do the work. That company has been used by the village for the same work the last few years, said David Cox, village administrator.
The actual bill for the work will depend on the size of the area treated and the amount of material used, the agreement with the company states.
Wikipedia says watermilfoil, native to Europe, Asia, and north Africa, is a submerged aquatic plant, and grows in still or slow-moving water. Introduced to North America in the 1950s, it is generally considered an undesirable invasive species here.
