The applicability of computer-oriented techniques to assist in the interpretation of brine data is demonstrated by the use of six programs on data from two example areas. These programs include a data tabling routine; routines for producing Stiff, Piper, and Ropes diagrams; programs for calculating ionic ratios; and programs for plotting maps of chemical data. The examples illustrate: (1) the range in water quality and contamination of potable water by brines in Stafford, Pratt, and Barber Counties, and (2) the change in water quality in the Arbuckle Group from southeast to south-central Kansas. ?? 1969.
