• Mr. Dean Lansing, Manager <br />Agricultural Consultants, Inc. <br />Colorado Analytical Laboratory <br />P, 0. Drawer 507 <br />Brighton, Colorado 80601 <br />Lithologic samples from Hole 1 were collected by a Wyoming <br />Fuel Company staff geologist on December 5th and Sth, 1979, during <br />drilling operations. Samples were collected from the cuttings as <br />they were discharged from the hole at one foot increments and com- <br />posited in sample bags every five feet. Air and fresh water were <br />used as the drilling media to prevent contamination of samples from <br />pollutants (reference - Power and Sandoval, 1976). The samples <br />were described at five foot increments and lithologies were grouped <br />together based on the descriptions where they were the same. The <br />samples were later taken to Agricultural Consultants' laboratory on <br />January 7, 1980, where the samples were divided into forty-four <br />separate analysis units based on the vertical sampling scheme <br />recommended in Wyoming Department of Environmental Quality Guideline <br />• No. 1 outlined as follows: <br />(1) Samples should be taken from or be representative of <br />material not greater than 10 feet thick. (Our samples were separated <br />out every 5 feet). <br />(2) Where lithologies have a thickness greater than 10 feet <br />but less than 30 feet, the samples collected may be composited for <br />analytical purposes, <br />(3) Where lithologies are greater in thickness than 30 feet, <br />the lithotypes should be divided into units not greater than 30 <br />feet in thickness for composited samples. <br />The overburden parameters outlined in Wyoming Department of <br />Environmental Quality Guideline No. 1 were utilized as the basic <br />analysis. At the request of the Colorado Mined Land Reclamation <br />• <br />-15- <br />
