Abstract Even in industrialized countries like Germany, drinking water quality is a sensitive issue. Despite a generally high level of drinking water safety, contamination events do occur. We address the question whether demographic change may cause a spatial mismatch between installed capacities at the supply side and actual demand by water users, thereby increasing risks of microbiological contamination. Our investigation is based on a quantitative analysis using the largest publically available data-set on drinking water quality in Germany. We found that the number of reported contamination events in areas affected by population decrease was about twice as high as in areas with a stable or growing population. The relative frequency of microbiological contamination was found to be significantly correlated with rapidly depopulating areas. We conclude that in regions with negative population development, a statistically higher risk of microbiological drinking water contamination may coincide with a greater risk of recontamination during a longer passage in the distribution network.
