The Assessment of Pollution in Zeza River Water through Microbiological Parameters

The environment pollution is the main problem in Albania and for Zeza River water as well. Zeza River flows through the Fushe - Kruja town and joins the Gjola River near Koder – Thumane and together go to Ishmi River (Saraci. R 2002). During September 2014- September 2015 the river has been monitored periodically in two stations. 1: Before Zeza River passes through the town of Fushe-Kruja (500-600m). 2: After the river passes the town. Stations of taking samples are presented by tables and graphics. It is made a specific and detailed study with the focus of microbiological monitoring, in order to evaluate the real conditions of water in Zeza River. There are assessed Faecal coliforms and Total coliforms, that are the most fundamental indicators for the fecal pollution by waste waters. It is made also the statistical elaboration of data and their presentation with graphics and tables. Samplings transport and water testing is done according to the rules of International Standards. Faecal coliforms are tested by plating methods and Total coliforms by MPN test. This research assesses the quality of water in Zeza River, based on the microbiological analysis. The maximal values of Total coliforms for the two station of Zeza River are taking during spring-summer 2015 and the maximal values of Faecal coliforms are taking during spring 2015. Zeza River water was grossly polluted by Total and Faecal coliforms organisms during 2014-2015. The discharge of industrial and urban wastes into the river and mismanagement of agricultural practices are causing high water pollution and river conservation is threatened.
