*Source for most fly ash data is EPRI CP-INFO Database3. Beryllium, Thallium, Mercury (bottom ash only) and Boron (bottom ash
only) are from the EPRI PISCES Database.6
**Source for rock data is US Geological Survey National Geochemical database. 7
***Source for most soils data is Shacklette and Boerngen (1984)8; Cadmium and Thallium data are from Smith et al (2005).9
