The project was sponsored by Procter & Gamble ETC. This case study showed the feasibility of implementing a new large catchment (~6000 km2, 1823 discharge points) on a short term and indicated which efforts are required to apply GREAT-ER on a large, ultimately pan-European scale. It was found that it is possible to simplify the river network without considerable loss of accuracy. This allows to gain time and reduce effort. Spatial concentration patterns of the anionic surfactant Linear Alkylbenzene Sulphonate (LAS) were predicted for this basin. LAS removal in waste water treatment plants is high (98-99.9%). However, since only 30-40 % of the wastewater in the Rupel basin is treated, predicted environmental concentrations (PECs) are quite high. More information can be found at BIOMATH, University Gent. In a second phase of the project, ERASM has sponsored the validation of the implementation of the Rupel in GREAT-ER by means of a boron monitoring campaign. The report is available in the download section . A new, updated, version of the Rupel data CD (version 1.1) is available as of May 2002 Top of Page
