The objective of this study is to determine the average Viking Formation water chemistry for the immediate area surrounding T. 23-24, R. 23W4. In order to obtain a truly representative average of the water chemistry data from a larger area had to be examined (T. 22-25, R. 23W4). All of the water analyses interpreted to represent Viking Formation waters were used to determine the "average" Viking Formation water, by calculating both the average concentration and the standard deviation of each of the major ions.
