Improving the prediction of future groundwater quality by analyzing concentration-depth profiles

摘要：

Prediction of groundwater quality evolution, both at the regional catchment scale and at the scale of drinking water well fields, suffers from uncertainty in (1) inputs of diffuse contaminants, (2) groundwater flow patterns and travel times, and (3) reactive processes within the aquifer. We tested how an approach based on measured concentration-depth profiles could be used to reduce prediction uncertainty, and whether reactive processes could be inferred from these profiles. The two examples show that prediction of groundwater quality evolution can benefit from uncertainty reduction through smart monitoring network design with multi-level wells as a technique to unravel the relevant geochemical processes.
