The southernmost part of the Netherlands consists of plateaus, covered by loamy soils and intersected by deep valleys. The streams are fed by numerous springs. The investigation documented here evaluated the relationship between spring water quality and loads at land surface, caused mainly by fertilisation and aerial deposition. Spring surveying, well suited to determining groundwater quality, was used. Investigations at 79 springs and 12 brooks consisted of field measurements and water sampling for analysing major components, 49 trace elements and the isotopes 3H and 18O. Evaluation of results showed some determinations to be not very reliable and in need of substantial adaptations. Studying concentrations in groundwater and springs involv...
