Description: Das Projekt "NOIRAIGUE - Teilprojekt B: organische und mineralische Kolloidpartikel im Wasser von Sumpfboeden an Quellen in Karstsystemen (OMIPAWAKA)" wird vom Umweltbundesamt gefördert und von Universite de Neuchatel, Institut de Geologie durchgeführt. In the catchment area of the Noiraigue system two types of waters are present: 1. weakly polar, acid, reduced waters with organic material stemming from natural peat bogs and 2. moderately polar waters containing organic material stemming from improved swamps. The two waters mix with each other and are thereby neutralized before entering the karst drainage system. The colloid's nature, fluxes and impact on the neutralization is the main topic of the present investigation. Since fluxes are highly dependent on season and rain fall, the study of the hydrologic systems is an important part of this project (subproject A). Since colloids are partially produced by biologic activity, the microbiologic system is studied in subproject C (e.g. Gallionella). During transport in the karst system, the waters loose about half of their organic material content. Colloids at the karst spring will be compared with those at the karst entrance in order to quantify the influence of the residence time within the karst system as well as transport and oxidation processes. Tracing of bacteria using bacteriophages will permit to quantify the transfer time of organic particles of 1 mym size in comparison with the smaller colloid particles.
