The Assessment of Microbiological Indicators in the Freshwaters of Drini River and Lezha Lagoons

In this study we investigated the level of pollution in surface water and sanitation in the sediments on the Drin River in Kune and Vain, through investigation of seasonal variations, the group of bacteria as indicators of microbiological contamination. These parameters include Total Coliform (TC), Fecal Coliform (FC) Fecal Streptococci (FS) in the surface water and sediments. The samples are taken during 4 seasons of 2012-2013. The samples of water and sediments for microbiological analysis are collected at fifteen monitoring points (5 sampling points in the Drini River along its length, from the bridge Zogaj - Balldre up in the Industrial area, while in Kune-Vain lagoons are defined and taken 4 points sampling on each lagoon. Last 2 sampling points belong to the estuary of the Drin River in the Adriatic Sea). The classification is made and comparisons with EC Directives 2000/60, WHO, USEPA, NIVA. According to the analytical evaluation of samples for microbiological indicators it was observed that the values of these indicators in the samples of sediments have resulted higher than in samples of water. The highest values were found in the sampling stations on the Drini River, followed by the sampling stations at the mouth of the Drini River. Average lower values of (TC), (FC) and (FS) in water, are found in autumn and winter, while the average values are found higher in the spring and summer. Average lower values of (TC), (FC) and (FS) in sediments are found in July '12 while average values higher are found in November '13.
