Saltwater intrusion is the flow of seawater flowing inland in freshwater aquifers. It occurs naturally to some degree in most coastal aquifers. Groundwater pumping can cause saltwater to be drawn toward the freshwater zones of the aquifer in coastal regions.
Van Essen Instruments offers a range of products for saltwater intrusion project. Electrical conductivity measurements from the CTD-Diver can be correlated with chloride concentrations to monitor seawater intrusion. This data provides valuable information for hydrologic modeling of seawater intrusion and coastal zone aquifer management.
