ABSTRACT
Hydrochemical studies generate large amounts of data of different parameters obtained in the field and reported by various laboratories. The first stage in data processing is to organize the data into tables. This stage is important and warrants some thinking. Have a look at Tables 6.1, 6.2, and 6.3. They contain the same data, but differ in their structure. Which of the three tables is “impossible” and which is most handy and most informative?
