Study and Interpretation of the Chemical Characteristics of Natural Water
TL;DR: The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from human activities.

Inorganic species in geologic fluids: Correlations among standard molal thermodynamic properties of aqueous ions and hydroxide complexes
TL;DR: Estimates of the speciation of major, minor, and trace elements in hydrothermal and metamorphic fluids throughout most of the crust of the Earth are facilitated by correlations among experimentally determined standard partial molal thermodynamic properties.

Modeling the Effects of Acid Deposition: Assessment of a Lumped Parameter Model of Soil Water and Streamwater Chemistry
TL;DR: In this article, a conceptual model of soil water and streamwater chemistry based on soil cation exchange, dissolution of aluminum hydroxide, and solution of carbon dioxide, all processes that occur in catchment soils and that have rapid equilibration times is presented.

A Procedure for the Fractionation of Aqueous Aluminum in Dilute Acidic Waters
TL;DR: In this article, a procedure was developed for the fractionation of aqueous aluminum, which results in the determination of acid-soluble aluminum, non-labile monomeric aluminum and labile moneric aluminum.

TL;DR: In this article, the results of experiments on solutions 4.53 x 10/sup -4/ to 4.5 x 10 /sup -5/ molal (12.2 -1.2 pp.) in aluminum, in 0.01 molal sodium perhlorate, were conducted to obtain information as to the probable behavior of aluminum in natural water.
