Water resource monitoring will determine the quality of water, identify its depreciation, and help policymakers make decisions that will preserve not only natural areas but also improve quality of life. Therefore the purpose of this paper is to evaluate the physical and chemical parameters of the locations where the river Lukac flows into the Erenik River. Erenik is a River in the western part of Kosovo. The water quality of the Ereniku River depends from anthropogenic activities, mainly from sewage discharges, from agriculture, as well as from various factors that perform their activity in the watershed of the Ereniku River. The samples were taken from the river in June 2017 in three stations (locations) and were analyzed the physical-chemical parameters such as: Iron, Manganese, Ammonia, Nitrites, Nitrates, Phosphates, Aluminum, spending of potassium permanganate, dissolved oxygen, blur, pH, electrical conductivity, Alkalinity, COD, BOD, N and P inorganic forms, etc. Water samples were analyzed in the physical-chemical laboratory such as: pH values, conductometry, turbidometry, atomic absorption method, spectrophotometric method and classical chemical analysis methods (volumetric). Parameters such as pH, temperature, hardness, blur are comparable to the qualities of Mountain Rivers, which are not significantly affected by human activities. The TSS, alkaline and EC values are higher where they show the influence of human activity and sewage, as well as the COD and BOD values show the impact of human activity.

Water is tested for the presence of total coliform bacteria, fecal coliform bacteria of fecal origin and mesophilic aerobic bacteria. These organisms are mainly used as indicators of water quality studies; their presence indicates that fecal material has polluted the water. Monitoring was conducted for 3 years, in 2008, 2011 and 2012 over 12 months, and the average monthly minimum and maximum are shown in the tables on monitoring the water in Lake Radoniq in Gjakovë. This study shows that water pollution is very important. In almost entire Lake area the presence of fecal coliform bacteria appears. For this numerous analyses have been made and methods through the filtration system, preparation of nutrient agar and incubation have been used. Such waters where there is interference and uncontrolled discharge of sewage, need common processing as precloration, coagulation, flocculates, sludge, filtration, final disinfection by chlorination where these processes are carried out regularly with success in the water treatment plant in RWC 'Radoniq' in order to offer consumers the best quality water.

Research paper thumbnail of Determination of COD, BOD5 and Bacteriological Parameters of Water in the River Basin of Ereniku

In this paper I intend to provide data as to the condition of the water in the Erenik basin and give ecological assessment (physical, chemical and biological) of water quality of the river Ereniku. Assessment is done in four seasons and in 13 points. For this numerous analysis have been carried out, among them is determination of COD (chemical oxygen demand), BOD5 (biological oxygen demand), as well as bacteriological parameters, as the most important parameters in determining the level of water pollution. Also from bacterial terms, total coliform bacteria were analyzed, fecal originating coliform bacteria and live mesofilic bacteria. Water samples were taken in polyethylene bottles of 500 ml, which are initially well cleaned and immediately analyzed in the chemical and bacteriological laboratory. Based on results it is clearly seen the pollution of this river and which needs a great care as well as treatment plant of wastewater from which comes major pollution. 1. Introduction Until in the pre-industrial period, water pollution problem was not worrying because the pollution was caused by small, mainly liquid discharges. In less populated areas without sewerage systems, today these problems are easily overcome by own natural cleaning capability of rivers. Industrial development and modern civilization led to the formation of large residential areas, with industry and intense agricultural development. This caused increased water discharge without any prior treatment, beyond self cleaning capabilities of water. River flows constitute the main sources of freshwater. The main sources of pollutants to the water environment are organic substances that come from urban and industrial discharges. During flow, immediately after discharge, decay of organic matter reduces the amount of oxygen and causes the release of ammonium, which although it is not poisonous, depending on pH and temperature, turns into ammonia, which is poisonous to living things in water. In natural conditions organic matter in the water come from soil erosion and dead biomass of plants and animals, they are not soluble and have slow composition. On the contrary, organic matters from human activity are soluble, distributed uniformly and very decaying, causing immediate intake of oxygen in the water. With increasing population density in the watershed increases the amount of organic matter in the water and decrease the amount of oxygen. Biological need for oxygen (BOD 5) is lower than 2 mg / l O 2 in basins with less than 15 residents / km2, and exceeds 5 mg / l O 2 /km2 in basins with more than 100 inhabitants / km2. Human activity causes the increase of the content of chemicals in aquatic environments, i.e. minerals. All these pose a risk to aquatic ecosystems and the man himself. Surface water contaminated by fecal discharges by people and animals, can carry many pathogens, such as bacteria and viruses, more manifested in densely populated areas, especially near cities.
