MICROBIOLOGICAL INDICATORS IN DRIN RIVER

The basin of Drin River include the Black Drin, White Drin and Buna River, as well as Shkodra, Ohrid and Prespa lakes. Black Drin and White Drin flow together in the territory of Albania until they meet the Buna River and discharge in Adriatic Sea. The Drin River is important to the economy of Albania, because the water used for agriculture, energy, sanitation and mining industry, fisheries, tourism and transport. Research are focused for the evaluation of microbiological parameters such us heterotrophic bacteria and faecal coliforms. The objective of this study was to evaluate the quality of water based on microbiological parameter such us heterotrophic bacteria and faecal coliforms. Sampling was collected during the river stream with two times per year frequency. All the procedure for sampling, storage, and analysis are according to European standards. We have used the MPN method for calculation of bacteria indicators, and the finally results are reported us CFU/100ml. The data obtained by this study showed that water is within the limits permitted by international standards, for surface waters used by people and agriculture.
