<\/a>Ground water chemistry is reflective of time-weighted averages of anthropogenic inputs originating from spatial and temporal patterns of land use. We developed an approach to examine potential relationships between land use-derived solutes and baseflow surface water quality using regional ground water and solute transport models linked to GIS. Our first test of this approach estimated chloride concentrations in surface water due to road salt transport through ground water in Michigan’s Grand Traverse Bay watershed.<\/p>\n

Further development of\u00a0 watershed-scale groundwater flow and transport models\u00a0 has been undertaken to examine the impacts of various land uses on nitrate concentrations.\u00a0 In Michigan, streams are predominantly groundwater-fed for much of the year.\u00a0 Therefore, understanding groundwater nitrate concentrations and fluxes is vital to understanding stream water quality.\u00a0 The figure on the left shows a preliminary simulation of total N concentrations in Cedar Creek, a small\u00a0 subwatershed of the Muskegon River in central lower Michigan.<\/p>\n
