Implications of GW flow and pathway studies -- The following figures show the delayed response of stream quality to land use inputs in the GW-dominated stream systems of southern NJ (Glassboro). Results are based on a 3-D GW flow (MODFLOW) and particle tracking (MODPATH) analysis of the Kirkwood/Cohansey surficial aquifer in the 400 square mile Glassboro area. The take-home message is that because of the long time of travel from points of GW recharge in the watershed to the point of discharge to streams, the chemistry of these GW-dominated streams requires a long time to respond to changes in changes in land-use practices.
