The Impact ◽  
Rhine Water

Reclaimed lakes (surface ≥3 m below sea level) in a coastal plain with formerly more or less stagnant flow conditions, act as huge groundwater discharge areas and convert the bordering land into groundwater recharge zones. The main consequences are: (1) the infiltration of fresh polder and river-Rhine water, both of poor quality; (2) the moving in of fresh groundwater of excellent quality, from relatively remote sandy recharge areas like the coastal dunes and Pleistocene uplands; (3) the encroachment of salt North Sea water along the west coast; and (4) the bleeding-out of relict brackish to salt water. The sluggish change in the spatial distribution of water types, leads to new possibilities of groundwater pumping for public water supply in and around the deep polders, in future. The chemical consequences are discussed. Salinization hazards for well fields in the coastal dunes and Pleistocene uplands may increase.

Rhine Water

Effluents from point sources (industries, communities) and diffuse inputs introduce pollutants into the water of the river Rhine and cause a basic contaminant load. The aim is to establish a biological warning system to detect increased toxicity in addition to the already existing chemical-physical monitoring system. To cover a wide range of biocides, continuous working biotests at different trophic levels (bacteria, algae, mussels, water fleas, fishes) have been developed and proved. These are checked out for sensitivity against toxicants, reaction time, validity of data and practical handling under field conditions at the river. Test-specific appropriate methods are found to differentiate between the normal range of variation and true alarm signals.

Rhine Water

Water quality modelling techniques havebeen used to evaluate and predict the influence of taken, projected and potential sanitation measures for domestic and industrial wastewater loads in the River Rhine drainage area. 15Because of serious eutrophication problems in the Dutch fresh water lakes, that are fed by the River Rhine, special attention is given to the quantification of sanitation measures that can reduce the nutrient concentrations. As a base for modelling the River Rhine water quality, a one-dimensional steady-state model MODQUAL (a modified version of the QUAL-II model) has been developed and applied on the riversystem downstream of Lake Constance, including the main tributaries Neckar, Main and Mosel and the Dutch branches IJssel, Lek and Waal. It is shown that the development of wasteloads and the introduction of biological (secondary) treatment since 1973, has resulted in a significant improvement of water quality components as DO, B0D5, COD, Kjeldahl-N and NH4-N. The influences of tertiary treatment directed on nitrogen or phosphorus removal and the introduction of phosphate-free detergents are quantified for various hydrological conditions.

This paper presents a statistical analysis of the pollution levels for heavy metals and organic micropollutants at 182 sediment stations in the city canals of Delft. High pollution levels were especially observed in the inner city canal sediments, probably related to the import of polluted river Rhine water. In contrast, the more-or-less isolated outer city sites were generally much less polluted. Regression analysis on the database generally showed highly significant correlations between individual heavy metal contents. The heavy metal contents were usually significantly correlated with polycyclic aromatic hydrocarbons (PAHs) as well. This points to one or more common sources for these micropollutants. Factor analysis and the K-means cluster analysis technique were applied on the above database; it showed a large cluster of stations, nearly all located in the outer city of Delft, characterized by relatively low heavy metal and organic micropollutants’ contents. Another cluster of 18 stations, mostly located in the inner city of Delft, possessed intermediate pollution levels, directly related with the supply of river Rhine water. Finally, the stations of a third cluster, situated in the inner city as well, were highly polluted, especially by local pollution sources. The above hypotheses were further supported by a more detailed statistical analysis for a number of inner city stations, together with 10-year river Rhine pollution data.
