In West Texas, water is extremely important. The following data
represent pH levels in ground water for a random sample of 102 West
Texas wells. A pH less than 7 is acidic and a pH above 7 is
alkaline. Scanning the data, you can see that water in this region
tends to be hard (alkaline). Too high a pH means the water is
unusable or needs expensive treatment to make it usable.† These
data are also available for download at...
