Abstract
Al-Faria watershed is located in the northeastern region of the West Bank. The watershed
extends for 30 km from Nablus in the west to the Jordan River in the east, with area of 331
km2
.Wadi Al-Faria area is considered an important agricultural resource in Palestine.
Fresh water is scarce in Palestine, and especially in Al-Faria area. Since more than three
million cubic meters of fresh water flow in the Wadi during winter months, the idea of this
research is to store this good quality fresh water in underground with minimum negative
quality impact and to make it possible for extraction during summer time when demand
reach the highest peak.
Through Vertical Resistivity Sounding, the underground lithological profile with a depth
up to 150 m is constructed. The investigated site locates in the lower part of Al-Jiftlik area,
and cover an area of 1.5 k
2m. A gravel layer with 20 m thick, and located by 20 m depth,
with total volume of 30X106
cm could be to store 8-10 mcm.
Deep infiltration ponds or injection wells are recommended to be used in ground water
artificial recharge because of low hydraulic conductivity ( 38.9 x10-6 m/s) that dominate
the soil cover and remnants of Lisan formation, which locate in some locations very close
to the surface which could influence the quality of infiltrated water through this method.
The hydrochemistry of the groundwater of the area shoes its un suitability for domestic
purposes, since it's EC is very high (≈4.0 mS/cm), and the chloride concentration is range
between 700 and 1000mg/L
