Tables 1, 2, 3, and 4 are summaries of heavy metal analysis of leachates conducted to date on Chapman fly ash samples, H-Coal No. 3, H-Coal No. 4, and Grand Forks slagging ash No. 1. The tables represent some of the primary and secondary drinking water heavy metals in addition to the metals of Be, Ca, Mg. Each of the samples were sieved in the mesh sizes indicated with pH and conductivity values also reported on the table. Preliminary indications are that the solid waste samples as received will probably not represent hazardous conditions in terms of the primary and secondary drinking water heavy metals with the exception of GFETC samples in conjunction with Hg. As of May 1, 1980 all samples have been analyzed for mercury, barium, cadmium, chromium, lead, silver, iron, copper, manganese, zinc, beryllium, calcium, and magnesium. We anticipate continuing the analysis of leachates for arsenic and selenium. Results to date indicate that the smallest particle sizes tend to leach the greatest quantity of metals. Accordingly, in our opinion, some consideration should be given to fixation techniques for the ultimate disposal of coal conversion solid waste residuals.
