Abstract:
The Torbalı-Fetrek
sub-basin is an area of significant agricultural and industrial importance
located in the Izmir Province of Türkiye. The region’s industrial,
agricultural, and domestic water consumption relies exclusively on groundwater
resources, attributing to the existing pollution and limited seasonal flow of
the Fetrek Stream. The water budget of the region for the year 2021 was
calculated separately for three primary consumption components: industrial,
domestic, and agricultural usage. Groundwater consumption was calculated as 9.52%,
10.87% and 79.61%, respectively. There is no tourism activity in the region,
and livestock is limited. Paleozoic aged marbles in Menderes Massif, Upper
Cretaceous limestone, Neogene, limestone/claystone intercalations and
Quaternary alluvium units represent the characteristic aquifers. Surface and
groundwater sampling was done from 36 different points in the region. According
to the results of the major ions (Na, K, Ca, Mg, HCO3, Cl and SO4),
the dominant cation was Ca and the dominant anion was HCO3 in
groundwater. According to the results of minor ions (Al, Sb, As, Cu, Ba, B, Hg,
Zn, Fe, P, Ag, Cd, Cr, Pb, Li, Mg, Mn, Ni, Se, Sr, U and Si), most of the
groundwater is suitable for domestic, irrigation and industrial usage. In the
water samples taken from the Fetrek River, a significant increase in total
dissolved solids and pollution loads is observed, particularly in areas where
wastewater is discharged into the river. Due to the region's regular population
growth and industrial development, it is necessary to impose restrictions on
unplanned groundwater abstraction. The river's water quality should be
protected and evaluated as an alternative to groundwater. Moreover, it is
advised to employ appropriate treatment procedures to re-use industrial
wastewater for agricultural purposes.
