116.1 Range encompasses 50% of data for organic compounds found in several U.S. analytical studies (adopted from Fricke, C., C. Clarkson, E. Lomnitz, and T. O'Farrell, 1985. Comparing priority pollutants in municipal sludges, Biocycle, Jan/Feb: 35-37).

Note: *Sludges containing more than 10 ppm of PCB's must be incorporated into the soil upon application, and sludges containing more than 50 ppm of PCBs are subject to TOSCA requirements.
