Groundwater is an important source of drinking water. Therefore; groundwater
contamination is a source of continuing concern. Groundwater contamination is unlike
surface water contamination, because it is difficult to define and harder to be contro
lled
and treated. It may also last for years or decades.
Deveh Spring area is an agricultural area in Lattakia. It suffers from many
environmental problems, so, it is very important to assess spring water vulnerability using
DRASTIC and create water vulnerability assessment map by GIS.
The map showed that the recharge water to Deveh Spring has a high and moderate
vulnerability to contamination. The area of high vulnerable groundwater zone is (82Km2),
which is about (48%) from the whole study area. The area of moderate vulnerable
groundwater zone is (40Km2), which is about (23%) from the whole study area. Sufficient
actions must be taken to protect water from contamination, through the integrated
management of groundwater resources.
This search shows the lithological, petrographical and physical properties of the dam,
and storage basin through rocks cors study taken from some wells in axis dam and storage
lake and surface samples therefore have shaped unpenetration and penetra
tion units. From
this study discern reduction degree pored with rise positions deep far from range
movement underground water and observed attachment pored grade cracs, Faults and
karstic, Karstic discerned in positions (campanian, turounian) Increase Karstic caves in
sinomanian positions from during tectonic cracs and naught being it in mastrichtian also
action space in area dry weathering above level underground water because movement
water across this cracs and vacuity.
Positions geological divided in location which credence at pored to three straps
(A, B, C):
A)-Hard weathering strap Positions assimilate in this strap cracs dense rocks advance
open cracs wobble between(3-5mm) and full of habit clay materials ,and compose dense
weathering strap assimilate pored rocks and area the thick (3-6m).and advance removal it
before starting in construction dam body because low resistance ,high cracs, capacity low
load
B) -Soft weathering strap Assimilate debris pile from split calcite rocks,and
compose penetrating rocks.
C) -Unpenetrating rocks strip Assimilate thick clay calcite positions from
unpenetrating rocks.
