AbstractNitrate (N-NO3) in groundwater, apparently related to agricultural practices, is of concern in Prince Edward Island. To evaluate how nitrate concentrations could evolve with climate change, a quasi 2-D infiltration model and a 3-D numerical model of groundwater flow and nitrate mass transport for the entire island were developed. After calibration, present-day recharge and nitrate loading suggest that, by 2050, nitrate concentrations in the aquifer would increased by 11%. When considering the effect of climate change, recharge is reduced, and concentration increases by a range of 11-17%, or by 25%-32% if adapted agricultural practices are also considered.
