Abstract |
: |
Geophysical, geological, chemical, and hydrogeological
investigations of the solid waste disposal landfill site of Al-Muasim in
northwest Wadi Ibraheem valley were carried out during the period 1414-1415
H. (1994-1995). The volume capacity of the site has been greatly exceeded.
Geophysical survey data indicate that the thickness ofthe buried solid wasteis
about 30 meters, and the base of the buried waste material is saturated with
moisture. Furthermore, underground water table .level in Wadi Ibraheem near
the landfill site is higher than its level in the southern end of the valley where
it intersects with Wadi Uranah. The difference in elevation is more than 200
meters.
In addition, chemical analysis of water samples that were taken from a
substantial number of wells through the valley shows higher levels of
concentrations of certain heavy elements such as Pb, Cd, and Cr along the
main valley. This may have been caused by the leakage of the surface water
from the dumpsite through the buried waste towards the underground water.
These elements may have spread out to other areas along the gradient of the
underground water towards the down stream side, or through the systems of
fractures that dominate basement rocks in the region.
Five alternative new sites for solid waste disposal have been sited by
this study to be used as an alternative to the current site. These new siteS are
located in Wadi Malakan, which represents the southern extension of Wadi
Ibraheem across its intersection with Wadi Uranah. They are at the
downstream side of the valley, and each site represents a natural closure by
alluvial deposits and is surrounded by a series of low to moderate relief hills
from all sides. The location of these sites satisfies most of the landfill sitting
considerations such as geologic and hydrologic conditions, accessibility,
available capacity, and other local and environmental conditions.
It is recommended that the use of Al-Muaism site for solid waste
disposal be terminated, and that the disposal process to be continued in one of
the alternative landfill sites in Wadi Malkan suggested by this study. Further
detailed engineering studies are strongly recommended to isolate Al-Muaism
site and reduce its potential hazard to the environment. We also recommend
that additional engineering geology investigations to be carried out at the new
sites in prder to produce the suitable designs that meet the environmental
regulations of the Kingdom of Saudi Arabia. |
