“…22 Colloidal manganese oxides can form by oxidation of MnO2 or reduction of MnO4-. 23 Cement. The degradation of cement phases [tricalcium silicate (C3S in cement nomenclature) and dicalcium silicate (C2S)] allows the formation of calcium silicate hydrate (CSH) colloidal gels.…”

This paper reviews potential sources of colloids and enhanced adsorption of radionuclides that may stem from materials introduced into a repository setting. Three major sources of colloids are examined: metals, cements, and organics. The sensitivity of colloids to chemical species, pH, time, temperature, radiolysis, redox state, gradients of the aforementioned variables, and microbial activity is shown. We consider these influences on colloid formation and sorption with respect to introduced materials. We also discuss areas that have not been addressed but may have consequences in a repository setting.

A paper contributed to and selected by the JOURNAL, authored by Stephen R. Jenkins (Active Member, AWWA), asst. prof., Dept. of Civ, Engrg., Auburn Univ., Auburn, Ala., and Jogeir Engeset (Student Member, AWWA), res., asst., Univ. of Washington, Seattle, Wash.In a recent study the cost of treating naturally occurring waters of Wyoming was shown to be small if rapid sand filtration plants were available. Unfortu nately, most Wyoming communities do not have existing sand filtration plants and therefore, the removal of manga nese by this method is uneconomical. Generally the benefit gained by remov ing the manganese will usually not justify the expense of building a filter plant solely for that purpose.
