This literature review examines potential sources of colloids and enhanced adsorption that may stem from materials introduced into a repository setting, with a view towards prioritizing future studies. Three major sources of colloids are reviewed: metals, cements, and organics. Know chemical influences on colloid formation and mechanisms by which introduced materials may become involved are considered with respect to gradients, chemical species, pH, time, temperature, radiolysis, redox state, and microbial activity. Areas that have not been addressed but may have significant consequences in a repository setting are identified.
