Abstract
    Besides the rivers Rhine, Meuse and Scheldt, approximately 130 small transboundary rivers flow into the Netherlands. These regional lowland rivers are ecological very valuable. Unfortunaltely these waters are heavily polluted and Dutch nature conservation areas close to the border are threatened. A first survey of water quality of regional transboundary rivers on a national scale gives an insight in the present hydrochemical situation and the relative contribution to the total transboundary water pollution. Solute concentrations in most regional transboundary rivers exeed water quality standards and levels measured in the three large rivers. Due to this, the contribution of regional rivers to the total transboundary load, especially heavy metals, is relatively high. On base of spatial variation of water quality it seems possible to distinguish several clusters of river basins related to upstream land use. To create efficient river management and conservation of the regional transboundary rivers international
