Swarzenski . Kindinger 1. INTRODUCTION As populations and industry migrate toward sought-after coastal zone real estate increased pressure on these fragile margins demands a realistic and comprehensive understanding of the underlying hydrogeological framework. One of the most threatened resources along these coastal corridors is groundwater and coastal management agencies have developed complex strategies to protect these resources from overexploitation and contamination. Obvious consequences of coastal groundwater mismanagement may include accelerated saltwater intrusion into supply aquifers inadequate groundwater supply versus demand and infiltration of organic and inorganic contaminants into aquifers. Two examples of proactive management strategies in direct response to threatened coastal groundwater resources include the construction and maintenance of injection barrier wells Johnson and Whitaker this volume and the construction of large-scale desalinization plants such as in Tampa Bay Florida Beebe 2000 . Leaky coastal margins where exchange processes at the land-sea boundary are naturally enhanced can include the following environments i carbonate platforms ii modern and paleo river channels iii geothermal aquifers iv shorelines that are mountainous or have large tidal amplitudes or potentiometric gradients and v lagoons where evaporation can force density-driven exchange Figure 1 . In these coastal environments facilitated fluid-solute exchange can play an important role not only for coastal groundwater surface water management . water budgets but also in the delivery of recently introduced contaminants to coastal bottom waters. This submarine input for nutrients and other waterborne constituents may contribute to coastal eutrophication and other deleterious estuarine impacts. 2004 by .
