Mr. Robert E. 'It•ousil <br />• November 11, 1986 <br />Page 2 <br />Calcium <br />Aluminum <br />Silicon <br />Titanium <br />Magnesium <br />Sodium <br />Potassium <br />Iron <br />[3ariuin <br />Phosphorus <br />Strontium <br />Although many of the elements listed in the analysis would be hazardous if present <br />in larger quantities and in puce form, the compounds present in the fly ash are not <br />hazardous because they are not leachable under naturally occurring <br />circumstances. This is evidenced by the examples of barium, chromium, lead, <br />selenium, and arsenic, which are listed in the trace element analysis, but were not <br />leached in the toxicity test. <br />If you have questions on the analysis, please contact me. <br />Very truly yours, <br />HAZEN RESEARCH, INC. <br />C.
