| TITLE: | The geochemistry and geochronology of the Yarkon-Taninim aquifer along the course Beer-Sheva - Yarkon-Taninim |
|---|---|
| PROBLEM: | The Yarkon-Taninim aquifer is one of the major water sources of Israel. Recent geophysical, chemical and isotopic findings call for a revision of the previously dominating assumption that the aquifer represents a single hydrological unit. |
| OBJECTIVES: | Location and characterization of recharge zones and examination of their connections with the main water bodies in the aquifer; tracing of flow paths and estimation of flow velocities; assessment of chemical rock-water reactions and location of anomalies; characterization of chemical evolutions and examination of the hydrochemical continuity of the groundwater system. |
| APPROACH: | Sampling of well and spring water in the study area, measurement of pH, Eh and temperature, analysis of major ions and of isotopes, to be followed by chemical data processing and evaluation of equilibrium, employing the WATEQ and PHREEQE computer codes. |

| COMMENTS ON DATES: | |
| CURRENT PROGRESS OR INTERIM RESULTS: | The Beer-Sheva region is not connected to the Yarkon- Taninim system. Yarkon and Taninim are two distinct and different hydrological systems. The Rosh-Haayen region contains two or three distinct groundwater bodies. The lower water bodies, surprisingly, appear to be younger and faster flowing. |
