Removing asbestos contaminated soil in Mercer County, New Jersey

The purpose of this action memorandum is to request and document approval to expend up to $1,924,000 to conduct a time-critical removal action at the W.R. Grace/Zonolite Site (Site) located in Hamilton Township, Mercer County, New Jersey. The proposed removal action will address asbestos contaminated soil on a portion of this approximate 8.4 acre site.

This removal action addresses the need to mitigate the potential threats to the local population, current site employees, and the environment posed by fibrous amphibole asbestos that was released into the environment from the former W.R. Grace/Zonolite processing of vermiculite ore and disposal of associated waste products at this Site.

High concentrations of amphibole asbestos posing a public health threat have been detected on the former W.R. Grace/Zonolite Site at concentrations as high as forty percent.
