Geochemical patterns in Coachella Valley

Abstract

Tens of thousands of samples of water have been taken from streams, springs, and wells for chemical analysis, without much use having been made of the results. Unfortunately, the chemists have been little concerned with any engineering interpretation of such analyses and the engineers have had no ready method of interpreting them. Consequently, engineers and agriculturists have usually limited themselves to consideration of only the total dissolved solids, or the total hardness, or possibly the amount of chlorides; the real significance of the analyses has been overlooked.

Preliminary delineation of natural geochemical reactions, Snake River Plain aquifer system, Idaho National Engineering Laboratory and vicinity, Idaho

“…The format for the hydrochemical facies diagram used in this report was developed by Piper (1944) and is similar to one designed by Hill (1940). The diagram allows the plotting of relative concentrations of major anions and cations and the chemical character of multiple water samples.…”

“…Pattern diagram was initially conceived by Hill [16] and later improved by Piper [27] and the detailed analysis of Hill-Piper trilinear diagram for post monsoon season (Fig. 2) is explained below using facies diagram.…”

Geochemistry of water in aquifers and confining units of the Northern Great Plains in parts of Montana, North Dakota, South Dakota, and Wyoming

“…Trilinear diagrams were used for analysis of the Lower Cretaceous aquifers. A computer code to prepare plots of trilinear diagrams, based on the diagrams of Hill (1940), was developed by Ruth Seidel and Joe S. Downey (Ruth Seidel, U.S. Geological Survey, written commun., 1980). Constant ion ratios are indicated in trilinear diagrams by changes that follow "tie lines" for two of the three axes.…”
