Kidder Point GAC, Delta and Northern Chemical

 Two acid sources for the plumes (1) leaked sulfuric acid from 30 years of sulfuric acid making, (2) more than sixty officially reported sulfuric acid spills at the site beween 1983 and 2004, alone.

Bay History. Northern Chemical site at Kidder Point examined in 1965 by consultants re a Superfund court case in Massachusetts

 Chemical company  Grace Brothers was part owner of Northern Chemical site at Kidder Point. The report below describes in detail the industrial processes  active there in the late 1960s. It was submitted to court in a Superfund case in Massachusetts. That case was later dramatrized in the feature movie "A Civil Action".
