• SOLTLSCO <br />Sail and Wn1er ConsiJraNs <br />P. O. Box 4647 <br />Grand Junction, Colorado 81502 <br />A sample of coal was received from 1. E. Stover and Associates in Lune of 1996 for carbonate <br />equivalent analysis. It was ground to pass through a I mm sieve, and sufficient distilled and <br />deionized water was added to it to make a saturated paste. The pH of the paste was measured, <br />and the sample was then subjected to vacuum to obtain an extract for subsequent conductivity <br />measurements. <br />An additional sample of the 1 mm sieved coal was treated with ]0% HCI and the ensuing <br />volume of carbon dioxide emitted was measured to acquire the carbonate equivalent in the coal. <br />The following data was observed: <br />pH--9. I <br />Electrical Conductivity--0.81 dS/m <br />• Carbonate Equivalent--0.22% <br />This data indicates that each ton of the coal would contain about 4.4 pounds of an acid reactive <br />form of carbonate. <br />Respectfully Submitted By: <br />f> _/ <br />~~ • ,~ `% ~jOCtrY <br />Daniel F.
