AbstractGroundwater residence times, and lag times between the reduction of sources of nitrate and the subsequent improvement in nitrate concentrations in surface water and groundwater in the Wilmot River watershed on PEI are examined through flow and mass transport modeling, and tritium age dating. A reduction in nitrate inputs could result in corresponding improvements of nitrate levels in shallow groundwater and associated base flow within 4-15 years. For groundwater at depths of 22-32 m and 52-70 m, similar reductions could take 11-40 and 33-50 years respectively.
