RE: Groundwater Analysis, Wilson Mine area Umetco Mineral Corporation Hot Springs, Arkansas

Dear Mr. Kreese:

RECD SEP 1 2 1994

Enclose please find results of groundwater analysis and sample number correlation for the August, 1994 sampling of the Wilson Mine Area monitor wells.

A table comparing the August, 1993 and August, 1994 analyses indicates small changes in the Ca, Cl, Na, S04 and TDS, mostly of an improving nature. Attached for your convenience is a well location map.

If you have any questions regarding these analyses, please contact Jack Moore at (307) 457-2311 or Tom Gieck at (303) 245-3700.

Sincerely,

~ke~-~~ Manager
