Water Quality Degradation of Krivaja Watercourse

Abstract

Based on the monthly monitoring of the relevant indicators of surface water quality during the period of analysis, from year 2006 to 2011, an unsa­tisfactory ecological status and frequent occurrence of the worst quality class was noted in the Krivaja watercourse. This situation considerably limits or prevents the use of water from this river for any purpose. Also, based on the data from the three measuring stations, the longitudinal distribution of the analyzed parameters and degradation of water quality along the Krivaja watercourse was found. Protection, revitalization and rational management of Krivaja waters as an im­portant water resource of the areas it flows through, would make this wate­rcourse deleted from the surface water quality "black spots" list. As soon as the identified problems have been overcome, apart from being a wastewater reci­pient, the Krivaja can be used for other purposes without the risk of adverse effects. Furthermore, its waters and coastline may again be attractive and usable (for the irrigation of the surrounding farmland and safe food production).
