Abstract

Ensuring good water quality is becoming a major challenge in urban areas. Urban aquifers may suffer pollution from different recharge sources such as water leakage from sewer and septic systems, seepage from rivers, seawater intrusion, and losses from water supply network among others. As a result, a wide range of organic pollutants are found in urban aquifers. Since these pollutants enter the groundwater environment through the aforementioned sources, their occurrence depends on the transport mechanisms as well as the chemical and biochemical processes that occurred simultaneously. Thus, a proper assessment of groundwater quality requires an understanding of all the processes that affect these pollutants. However, the quantification of the...
