Various graphic methods are in vogue for study and interpretation of water quality data. However, it is a paradox that none of the methods gives a specific classification of waters. The prevalent trilinear diagram of Hill-Piper can be effectively used for geochemical study of water but it has limitations in classifying different types of waters. In the paper, a modified diagram has been proposed which can be utilized for (1) classification of natural waters (2) geochemical study of waters like base exchange, sulphate reduction, mixing etc. and (3) to find suitability of water for irrigation purpose. The proposed diagram is a modification of Hill-Piper diagram, with a view to extending its applicability in representing water analyses data efficiently. To illustrate the applicability of the diagram two case histories are discussed. |
