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.

Quality Status

The Dendeng River is vital for economic sustainability and viability for the community, industry and commerce around the flood plain of the river as well as raw water sources of the Kupang PDAM. However, increased domestic and industrial waste disposal along the river has caused severe pollution. One way to maintain the quality of the river is by continuously monitoring the pollutants and applying technology control as well as controlling strategy. The aim of the research mainly is to establish the water quality status of Dendeng River by water pollution Index method based on parameter physics and chemistry, i.e. pH,  DO, COD, BOD, TSS, TDS, NH3-N, NO2-N, NO3-N, and PO4-P. The research was carried out based on field survey and sample examined in situ and in laboratory. The removal of water sample from Dendeng River conducted based on composite sampling as many as six point locations of Dendeng River as representative of upstream up to downstream zone. The quality status of Dendeng River is in good condition to lightly polluted with a pollution index value of 0.6 to 1.52. Value of the DO, BOD, COD, and phosphate content were higher than the allowable class 1 standard.  The Water Quality Index value of Dendeng River was 86.67, which is included in the good water quality class.

In the present study water quality assessment and land based sources of pollutants discharged into the Halda River through four major canals were investigated. The ranges of pH, DO, BOD, NO3-N, PO4-P, chloride and total alkalinity of the collected samples varied from 7.1-8.8, 3.35-4.70 mg/L, 0.055-5.0 mg/L, 0.12-3.1 mg/L, 0.06-0.16 mg/L, 8.4-69.30 mg/L and 73-220 mg/L, respectively. pH, DO, BOD showed significant changes at Mondakini Canal and Chengkhali Canal for monsoon, post-monsoon and winter (p <0.05) while chloride at Chengkali Canal for all seasons (p≤0.05). Moreover, TA, NO3-N and PO4-P exhibited significant variation in the concentration at Mondakini Canal, Madari Canal and Chengkali Canal for three seasons (p ≤0.05). River Pollution Index indicated that the water of river at Mondakini Canal, Madari Canal, Chengkhali Canal and Khondakia Canal varied from low to moderate pollution. According to the interviewers, the Halda River is being polluted due to industrial waste (53%), sewage contamination (20%), tobacco farming (13%), rubber dam (8%) and sand extraction (6%). Therefore, necessary preventive measures should be taken in order to control the unwise and unauthorized discharge of harmful pollutants into the Halda River for the better management and conservation of natural resources.

Temporal Transformation

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.
