Abstract
Located in a region known for its scarce water resources, The Litani River Basin,
totally contained within Lebanon’s borders, is endowed with significant water
resources that have been at the centre of Lebanon’s water supply, agriculture and
hydroelectric development plans. However, many years of civil strife and foreign
occupation compounded with proliferation of uncontrolled urban, agricultural
and industrial growth have taken their toll on the quality of the basin’s surface
water and potentially its groundwater quality conditions.
This paper reports on findings from a study with the objective of assessing
groundwater quality conditions in the Upper Litani Basin (ULB) based on data
collected through an extensive water quality survey funded by the USAID as a
component of its initiative to support local government efforts to manage water
quality conditions in the country. The data is composed of two sampling sets
representing summer and winter conditions and include several key water quality
indicators. The paper focuses on the methodology and results of a geostatistical
analysis of the sampled groundwater nitrate concentrations. The analysis
produced two sets of georeferenced nitrate concentration and probability of
exceedance maps representing winter and summer conditions. The results
indicate a significant, widespread and persistent nitrates contamination of
groundwater in the ULB. Nitrate levels in groundwater exceed standard limits
for drinking water in many parts of the basin.
