Tracking Of Major Ion Concentrations in Aquifer Systems for Source Water Protection and Safe-Yield Consumption

摘要

The hydrologic stresses within an area affect the way water moves through the by drogeologic system and can influence changes in water quality. The potentiometric surfaces of aquifers respond to changes in these stresses proportional to the magnitudeof the applied stresses and the hydrogeologic parameters, which define the system. Hydrologic stresses that can potentially affect water quality in aquifer systems by ing different quality waters include precipitation: evapotranspiration; rivers, creeks,lakes, and drainage canals; irrigation; recharge and discharge areas; vertical leakage of water between aquifers; and wells. If hydrologic stresses simply moved waters of similar water quality makeup, water quality changes would not occur. The water quality degradation of wells and aquifer systems in Florida and many parts of the world occurs through the lateral intrusion of coastal seawater or the upconing of brackish or saline water. Lateral intrusion of seawater can occur through over pumpagc and the failure to maintain a positive potentiometric divide between the well field and the ocean or saline water body.
