Description
Groundwater colloids may be inorganic or organic or a mixture of both. Concentrations, chemical composition, structure, particle size and charge vary with the geochemical characteristics of the aquifer system. While granite aquifers tend to contain mostly inorganic colloids, aquifer systems with lignite strata (as in Gorleben, Niedersachsen) contain mostly organic colloids (water-soluble humic acids, so-called humic colloids). The concentrations of the colloids in groundwater depend on their availability in the sediment and in the salt concentration of the groundwater
Abstract (German)
Grundwasser-Kolloide koennen sowohl anorganischen als auch organischen Ursprungs sein, wobei in vielen Grundwaessern eine Mischung beider Kolloidarten auftritt. Die Konzentration, die chemische Zusammensetzung, die Struktur, die Partikelgroesse und -ladung variieren stark und sind abhaengig von der geochemischen Natur des Aquifersystems. In granitischen Aquiferen findet man ueberwiegend anorganische Kolloide, waehrend in Aquifersystemen mit Ligniteinlagerungen (z.B. Gorleben/Niedersachsen) ueberwiegend organische Kolloide (wasserloesliche Huminstoffe, sog. Humin-Kolloide) gefunden werden. Die Menge der Kolloide im Grundwasser ist von deren Verfuegbarkeit im Sediment und vom Salzgehalt des Grundwassers abhaengig. (orig.)
