“…Rating of the water quality according to the WQI is given in the Table 1. This index has already been developed for Jaffna peninsula of Sri Lanka (Harshan et al, 2017). As a further attempt, this study illustrates the developing of the WQI for surface water and groundwater in CKDu prevalence area in Moneragala District in Sri Lanka.…”

Total of 152 water samples from CKD/CKDu endemic areas and 30 water samples from non-CKDu prevalent areas in the Moneragala District were collected separately. pH values of water samples varied from 5.04 to 8.37 which are within the permissible limit prescribed by World Health Organization. More than 15% of water samples showed low Dissolved Oxygen (DO) values indicating heavy contamination by organic matter. Electrical conductivity was high ranging between 32 and 2865 µS/cm indicating higher mineralization in groundwater. The major ion chemistry reveals that the array of abundance of cations was variable as Na + > Ca 2+ > Mg 2+ > K + in dug wells, Ca 2+ > Na + > Mg 2+ > K 2+ in tube wells and Ca 2+ > Na + > K + > Mg 2+ in surface waters, while anions varied as HCO 3->Cl->SO 4 2->Fin water samples in both seasons. Computed WQI, 43%, 33%, and 82% for dug wells, tube wells and surface water respectively were in good water quality in this area, while waters in 30% and 25% of dug and tube wells respectively exceeded the value of 100 showing not suitable category. Considering irrigation quality, 88%, 93% and 96% of dug, tube and surface waters respectively were less than the permissible level. SAR values in the study area ranged from 0.08 to 4.91 meq/L by showing no danger of sodium as per SAR. The bulk of studied waters are appropriate for irrigation according to Residual Sodium Carbonate (RSC). Considering KR and PI, majority of water samples of the study area are suitable for irrigation purposes.

“…From Topilla (1280 m) to Sitnica's confluence into Ibër the quota is 497.2 m, its absolute fall is 782.8 m, whereas its relative fall is 7.2%. 24 The average height of Sitnica River is 734 m and only 7.8% exceeds 1000 m. The Sitnica river network density calculated based on the Neumann formula is 824 m/km 2 on the right side, whereas on the left side is 512.8 m/km. 2 9 The river is characterized by a quiet hydrological regime with an average flow rate of 12.9 m³/sec.…”

“…2,23 Sitnica River is endangered by a considerate number of agricultural areas, settlements with no adequate solution for the elimination or treatment of polluted waters, as well as by major industrial sites without an adequate solution. 24 The water quality of Sitnica River is affected by a large number of various pollutants; however, the environmental problems of this river are mainly the result of the pollution from untreated industrial and wastewater discharges as well as from agricultural infiltrations throughout the flow. One of the complicated issues in environmental management is communicating the condition of the environment to decision-makers and the public.…”

The main goal of this work is to show water quality and impacts on Sitnica River. Based on the previous studies, the main cause of the deterioration of Sitnica River water quality is anthropogenic activities, including wastewater, industrial, and agricultural discharge. This paper presents the assessment of the Sitnica River water quality by applying the Canadian Water Quality Index (WQI) in 16 monitored parameters, such as water temperature, turbidity, electrical conductivity, pH, dissolved oxygen and O 2 saturation, biochemical oxygen demand, chemical oxygen demand, etc. The parameters were measured in spring, summer, and fall, at 10 monitoring stations in the Sitnica River flow, from the spring to its confluence with the Ibër River. Based on the results obtained according to WQI, Sitnica's water quality varies from WQI-46 to WQI-95. The average WQI for the whole measurement period has resulted to be 63.5, meaning that the water of Sitnica River belongs to the marginal category. This indicates that the river has poor quality due to the effect of pollutants from various sources. This confirms the urgent need to undertake serious actions in monitoring the river and in managing it properly.
