This paper aims to evaluate the environmental condition of the „Gjanica” river by analyzing
different physiochemical parameters. Pollution has been present in this river since the beginning of
industrialization and urbanization of the city of Fier, Albania.
The main sources of surface water pollution in this country are wastewaters containing organic substances,
soluble phosphorous and nitrogen compounds that favor the eutrophication process. A major
pollutant of this river has as its source also the oil refinery that discharges untreated waters.
Sampling was carried out at 5 points along the „Gjanica” river, points in which there are significant
changes of allowed values of surface water parameters.
Experiments carried out are: pH determination, Redox potential determination, Electrical conductivity
determination, dissolved O2, BOD5, Alkalinity, Chlorides. The assessment of natural waters quality is
determined on the physical-chemical parameters comparing with the allowed values in the EU Water
Framework Directive.

Key words

water; wastewater; eutrophication; physiochemical parameter; pH, BOD
