| Abstract: | A water-chemistry evaluation was made of the available springs and wells in Amman and vicinity. Trihalomethanes (THM) were
found in all analysed samples with concentrations ranging from 0.2–31.88 μg/L. The probable sources of trihalomethanes in
the aquifers originate from three sources: (1) chlorinated Deir Alla surface water, (2) reaction of excess chlorine in the
leaky, corroded water-distribution network with organic matter in the vadose zone, and (3) sewage seepage from cesspools in
the area. Total organic carbon (TOC) ranged from 0.2–1.4 mg/L. Its probable source is either from the vadose zone or the treated
surface water at Deir Alla. It was found that TOC was of vital importance in the formation of THM in the presence of chlorine
from the water-distribution system.
Major ionic composition of the analysed samples reflected the limestone lithology of the aquifer in the investigated area.
Heavy-metal content was relatively low due to the high pH of the groundwater samples.
