Past industries include Rockford Varnish, Rockford Coatings Corporation and Rockwell International Graphics. Some of these industries have documented use of chlorinated solvents, the main chemicals of concern for the project area. Past surface spills appear to have been the primary sources of Area 11 surface and subsurface soil as well as groundwater contamination. Chlorinated industrial solvents found in the remainder of the Southeast Rockford Project were detected in some Area 11 samples at low concentrations. Non-chlorinated solvents, often associated with petroleum products, however, were found in such high concentrations in Area 11 that the detection limit of the analytical equipment had to be raised considerably. There may have been relatively high concentrations of chlorinated solvents in Area 11 samples, but they may not have been detected because of the high detection limit of the analytical equipment. | | | Date Created: | 05 25 2012 | | | Agency ID: | | | | ISL ID: | 000000042522 Original UID: 22031 FIRST WORD: Southeast | |
