我們發表了關于自然水域的地球化學及其與巖石和礦物在近地表條件下的相互作用的原始研究。覆蓋范圍包括理論，實驗，和模型論文處理這個主題領域，以及論文提出的自然系統的觀察，強調主要過程。該雜志還提供“信件”類型的論文供快速出版，并對特別廣泛的興趣或當前主要爭議的主題提供有限數量的評論類論文。

We publish original studies relating to the geochemistry of natural waters and their interactions with rocks and minerals under near Earth-surface conditions. Coverage includes theoretical, experimental, and modeling papers dealing with this subject area, as well as papers presenting observations of natural systems that stress major processes. The journal also presents `letter'-type papers for rapid publication and a limited number of review-type papers on topics of particularly broad interest or current major controversy.
