碳酸盐含水层内的水通常根据水文学进行分类。这种分组对于理解含水层中作用的地球化学过程的重要性取决于具有独特化学性质的类别。对来自宾夕法尼亚州的碳酸盐水进行了 166 项可靠的化学分析，并根据水文基础进行了分组，并通过逐步线性判别函数分析对分组进行了测试。两个参数（方解石饱和度和平衡二氧化碳分压）足以在 0.005 置信水平下区分各组，并为研究碳酸盐流域内水域的地球化学演化提供可靠的方法。
Waters within a carbonate aquifer have often been classified on a hydrologie basis. The significance of such grouping to the understanding of the geochemical processes acting in the aquifer is dependent on the classes having a distinctive chemistry. One hundred sixty-six reliable chemical analyses of carbonate waters from Pennsylvania were grouped on a hydrologic basis, and the groupings were tested by a stepwise linear discriminant function analysis. Two parameters (degree of calcite saturation and equilibrium carbon dioxide partial pressure) are sufficient to distinguish the groups at the 0.005 confidence level and provide a reliable way to examine the geochemical evolution of the waters in the carbonate drainage basin.
