In 2000, at Alewife Neighbor, Inc’s and Alewife Study Group’s request, the Environmental Protection Agency (EPA) investigated the top six-inches (aka “the protective cover”) of the former W. R. Grace site, now IQHQ’s property. The EPA concluded that as long as the top six-inches remain undisturbed, the site was safe.
Alewife Study GroupASG's mission is to enhance the quality of life & protect public health of North Cambridge neighbors near the IQHQ site - formerly owned by WR Grace.
