The pond at the Millbrook Quarry will undergo treatment for 3 to 4 weeks in an effort to eliminate an infestation of zebra mussels, a condition of its waters that was confirmed by state environmental officials in 2002. The treatment is not expected to pose a threat to non-molluscan aquatic wildlife, vegetation, or land-dwelling creatures at the site. Officials expect the one-time treatment process will provide protection from the possibility of future infestation for 33 years. Zebra mussels were first discovered in North America in 1988, in Lake Saint Clair, a lake between Lake Erie and Lake Huron. By 1990 they appeared in all of the Great Lakes. It is believed that the mussels were accidently brought over from Europe on the hulls of ships.
