This study investigates the feasibility of management of aquifer recharge (MAR) in Lebanon by designing well barriers to remove seawater intrusion from the fractured carbonate aquifers. Groundwater flow and saltwater/freshwater 50% sharp interface have been modeled along the coastal area using the Ghyben-Herzberg theory. The groundwater flow simulations have been supported by field transmissivi...

The objective of this study was to determine the primary removal mechanisms of endocrine disruptors such as steroidal hormones present in reclaimed water, specifically 17β-estradiol, estriol, and testosterone, during groundwater recharge via soil aquifer treatment (SAT). Steroidal hormones were quantified using enzyme-linked immunosorbent assays. Bench-scale studies and laboratory-scale soil co...

Vulnerability assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and land use planning. This contribution aims at estimating aquifer vulnerability by applying the DRASTIC model as well as utilizing sensitivity analyses to evaluate the relative importance of the model parameters for ...

Experiments in batch equilibrium system were carried out to evaluate the importance of physical and chemical factors determining the sorption efficiency of humic substances (HS) on aquifer material, which has been used for artificial recharge of groundwater (ARG) in drinking water production. Results showed that an increase of the amount of clay in the aquifer material and a decrease of pH in w...

Trace organic compounds (TrOCs), mostly found in secondary effluents, have a potential impact on the environment, affecting surface water, groundwater, and especially aquatic ecosystems. The present study focuses on oxidation of five selected TrOCs in column experiments, by simulating Soil Aquifer Treatment (SAT) integrated with Fenton-like reaction, using Granular Ferric Hydroxide (GFH) as a c...

Infiltration techniques for managed aquifer recharge (MAR), such as soil aquifer treatment (SAT) can facilitate low-cost water recycling and supplement groundwater resources. However there are still challenges in sustaining adequate infiltration rates in the presence of lower permeability sediments, especially when wastewater containing suspended solids and nutrients is used to recharge the aqu...
