The Borska Reka river (47 km long, 373 km2 of basin area) is located in eastern Serbia and it is the biggest tributary of the river Veliki Timok. It is also one of the most polluted watercourses in Serbia. Using the data of the Republic Hydrometeorological Service of Serbia, the paper analyzes water pollution using the combined physical-chemical WPI index (water pollution index) over two periods: 1993-1996 and 2006-2009. The analysis of parameters showed significantly increased values of heavy metals (especially iron and manganese) which are indicators of inorganic pollution (primarily because of mining), but also increased values of organic pollution indicators (Biological Oxygen Demand-BOD5, ammonium, coliform germs), as the result of uncontrolled domestic wastewater discharge.

The main objective of the research is a complex assessment of the actual ecological status of Salgir River waters based on several methods: visual survey of the watercourse as well as studying spatial and temporal transformation of water quality and determining the degree of water pollution by means of an integral criterion –water pollution index (IES) and bioassay techniques carried on seeds of two test crops (cress salad and wheat), and also zoning a watercourse according to several criteria. The assessment found a tendency to increasing degradation of water quality due to the increase of the anthropogenic load (increase in water abstracted from the river). The typical pollutants in the Salgir river are petroleum products, phosphates, lead, copper, biological oxygen uptake (BOU5). Phosphate content is in the range of 5.5–27.5, lead – 3.06–6.67, copper –1.02–4.52 MPC. The most powerful source of pollution of the river is the treatment facilities of Simferopol. The results of this comprehensive study made it possible not only to reflect the real situation at the water facility, but also to highlight sections of the river where a set of measures aimed at reducing/preventing the consequences of anthropogenic impact should be carried out as a priority.

The problems of drinking water quality have been considered in some settlements of the Turkivskiy district of Lviv region, in particular concerning the content of Nitrogen compounds. 20 sources of decentralized water supply were investigated. It was found that the main hydrochemical indicators of water samples mainly met the requirements for the degree of contamination of hygienic classification of water bodies. At the same time, analyzing the samples for the presence of nitrogen compounds, it was found that in the tested samples: the content of nitrate ions fluctuated within 0,02 - 016 mg/dm3 (average annual values did not exceed the permissible value); the content of ammonium ions is in the range of 0.5-2.8 mg/dm3, which did not significantly exceed the maximum permissible value. At the time, analysis for NO3- showed an excess of acceptable values in almost all samples by 1.3 у 4.2 times. It was found that the amount of nitrates decreased with the transition from the alluvial aquifers to the indigenous ones, where the average content was 108.9 mg/dm3 and 86.8 mg/dm3, respectively. This is probably due to better protection of the bedrock from surface contamination, greater capacity of the corresponding aquifers and their deeper occurrence. According to the average value of the water pollution index for the nitrate group, the studied objects of decentralized water supply belong to the second class ‒ moderately contaminated. The correlation between the water pollution index by nitrate group and the population morbidity is calculated to be direct and sufficiently high (0.73). The most associated indicators of water quality are diseases of the circulatory system, blood and hematopoietic organs, digestive organs, endocrine and urogenital systems.

The Assessment of the Surface Water Quality Using the Water Pollution Index: A Case Study of the Timok River (The Danube River Basin), Serbia The Timok River (202 km long, 4547 km2 basin area) is located in East Serbia. It is a right tributary of the Danube River and one of the most polluted watercourses in Serbia. On the basis of the data provided by the Republic Hydrometeorological Service of Serbia, the paper presents an analysis of water quality and pollution using the combined physico-chemical WPI index (Water Pollution Index) calculated for two periods - 1993-96 and 2006-2009 at four hydrological stations: Zaječar-Gamzigrad (Crni Timok River), Zaječar (Beli Timok River), Rgotina (Borska Reka River) and Čokonjar (Timok River). The following parameters were taken into consideration: dissolved O2, O2 saturation, pH, suspended sediments, Five Day Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (CODMn), nitrites, nitrates, orthophosphates, ammonium, metals (Cu, Fe, Mn, Hg, Ni, Zn, Cd), sulphates and coliform germs. The average WPI values were calculated for the observed periods based on the comparison of the annual average values of the listed parameters and defined standard values for the I water quality class (according to the Regulation on the Hygienic Acceptability of Potable Water of the Republic of Serbia). The highest pollution degree was recorded in the Borska Reka River, where heavy metal levels (especially manganese and iron) were significantly increased. These metals are indicators of inorganic pollution (primarily caused by copper mining). Also, increased values of the organic pollution indicators (ammonium, coliform germs, Five-Day Biological Oxygen Demand - BOD5) in the Borska Reka and the Timok rivers are the result of uncontrolled domestic wastewater discharge.

The fluctuation dynamics of average annual, average monthly and minimum annual discharges of the Guyva River for 1938–2010 years on the Horodkivka, Peski gauging Stations is given. Comparative results of chemical composition and water salinity in the Guyva river are given for the periods of 1967–2015. The article presents the results of environmental assessment of water quality on the criteria of components of the salt content pollution, environmental sanitation indexes and content of specific substances toxic effects. The water pollution index is calculated and the overall assessment of pollution is made by the whole set of indicators. Keywords: fluctuations in water consumption, chemical composition, mineralization, quality assessment, water pollution.

Coastal area of Semarang City is susceptible to water pollution and one of which is due to sea water intrusion. Diarrhea is an infectious disease that causes more than 26,93% of mortality in children under five years old and cases average over 30% in coastal area of Semarang City. The aim of this study was to evaluate assotiation between Water Pollution Index (WPI) and incidence of diarrhea in children under five years old. This type of research is an observational analytic study with a cross sectional study design. Sampel consisted of 18 respondens from 7 districts in coastal area of Semarang City. Independent variable is water pollution index which is calculated based on parameters of pH, salinity, TDS, and E.coli. Dependent variable is incidence of diarrhea under five years old. Data analysis used univariate and bivariate analysis using rank spearman correlation and Geographical Information System (GIS). Result found moderate category of water pollution index in Mangkang Kulon, Mangunharjo, Mangkang Wetan, and Bandarharjo. We identified associations between water pollution index (p 0,014, r: 0,857), E.coli in water (p 0,017, r: 0,842), salinity in water (p 0,013, r: 0,860), TDS in water (p 0,011, r: 0,871) and incidence of diarrhea. There is no relationship significantly between pH in water (p 0,782, r: -0,130) and incidence of diarrhea. WPI provides information on water quality and contaminants in water has potential trigger to digestive disorders. Cases of diarrhea occured by pathogenic microbiological, material, and chemical compounds. Conclussion, there is assotiation between water pollution index and incidence of diarrhea in coastal area of Semarang City.
