Results <br />of soil sampling on 6-4.99 indicated the following results from areas with the <br />greatest quantities of spills and with in effected area with dead sagebrush: <br />1. 150' North East of the environmental trailer 200' below the barren <br />liquor leak was 2.160 umhos/cm. <br />2. 400' North West of the environmental trailer and 100' below the barren <br />liquor leak was 1.5 umhos/cm. <br />3. The barren liquor spill near the pipeline cross-over, 25' off the road <br />was 3.0 umhos/cm. <br />4. The pregnant liquor leak 300' from the South West corner of well lA- <br />SHR was 3.7 umhos/cm. <br />For comparison purposes, we took a sample from native soil in an undisturbed <br />area 100' North East o1.' monitoring we119O-2. The results from this soil sample <br />was .380 umhos/cm. <br />iii iiiiiiiiiiiii iii <br />Nahcolite <br />White Rlvar Nahcolite Minerals, Llmltad Llabllity Company <br />P. O. Drawer 72, 3200 Co.
