ABSTRACT
The necessity of environmental protection, public health and tourism development is today one of the main priorities in Albania. Even though our country is very rich with water resources due to wide river nets and mountains direction from east to west, their microbiological water quality has been long discussed. Drino and Vjosa are the main rivers in the southern region of Albania and they are shared between Greece and Albania. In Albania, they are under the influence of anthropogenic pollution, which is connected to the untreated urban discharges, waste effluents, agricultural activities etc. The aim of this study is to assess the microbiological water quality of these rivers in Albania based on the seasonal changes of bacterial parameters. Samples are collected every season from Summer 2012 until Winter 2013 - 2014. Seven sampling stations are established along Drino and Vjosa Rivers for this study. Two of these stations are located in the border points, where the rivers come from Greece to Albania. This is done to study whether the water is contaminated in Greece or it is polluted in Albania. The microbiological examination of water samples is made to determine the quantity of Faecal coliforms and Faecal streptococci as indicators of fecal pollution. These indicators are detected via Multiple -Tube Fermentation Technique or Most Probable Numbers (MPN) technique. According to preliminary results, there is a high load of Fc (until 1.2 x 10⁷ bacteria/100ml) and Fs (until 2.3 x 104 bacteria/100ml) in water of five sampling stations, above the rates allowed by European Union for surface waters. While the microbiological quality of water in two stations near the border with Greece is within the rates allowed. The human impact on the microbiological water quality of Drino and Vjosa rivers is more than evident. We will notice that this situation will continue to worsen for as long as urban emissions of all kinds are not handled. Uncontrolled use of such waters could have serious environmental and public health implications especially when water is used for agricultural purposes, aquaculture, swimming etc.
