ABSTRACT
This paper aims to advance
previous studies on the iron and manganese content in groundwater of Rrogozhina
aquifer (western Albania) and to show the factors which control the content of both
iron and manganese in groundwater of this aquifer. Rrogozhina aquifer represents
an important groundwater source of the country whose relevance was highly increased
during recent years because of the demographic expansion in this
region. This is a typically multi-layered artesian aquifer which consists of sandstone
and conglomerate with high heterogeneous permeability. The groundwater mostly belongs
to HCO3-Mg-Ca hydrochemical type. The content of soluble iron and manganese
in groundwater ranges from 0.004 mg/L to 0.7
mg/L, and from 0.0
mg/L to 1.147 mg/L, respectively.
Deeper the groundwater occurs and longer the distance from the recharge zone, higher
is the content of Fe2+ in groundwater due to gradual depletion of O2 in groundwater. The content of iron
is higher than that WHO and EU recommended, which were 21% and 25% respectively, while the content of manganese were 17%
and 23%, respectively. Abstraction of groundwater with high
quantities by deeper wells would be accompanied by increase of dissolved iron and
manganese content in groundwater which should be treated (with aeration) in order to decrease the content of these two elements in the water before using it.
