Characterization of the Hydrochemistry, Scaling and Corrosivity Tendencies, and Irrigation Suitability of the Water of the Rivers Karawa and Iyiaji

Assessing water quality is necessary to ascertain its viability for domestic, industrial, and agricultural purposes. A total of 48 samples were, respectively, drawn from the Rivers Karawa Iyiaji located in Ezeagu Uzo-uwani which are typical rural areas Enugu State, Nigeria. These were taken two seasons (early rainy season late dry season). Physicochemical properties determined using standard methods. The scaling corrosivity potentials evaluated Larson-Skold index, aggressive Puckorius Ryznar stability index models. Additionally, seven irrigation evaluation criteria, as well spatial distribution maps, used determine suitability river waters purposes interpolate parameters. Major ion chemistry was assessments. physicochemical fell within recommended values. However, NO3− greatly exceeded range both rivers. cations anions River Ca2+ > Mg2+ K+ Na+ Cl− SO42− HCO3− CO3− PO4−, while those >NO3− PO4− CO3−. piper plot showed predominance Mg+, Cl−, assessment indices indicated that suitable In addition, models predicted have high potentials. Specifically, suggested it severely corrosive, Langelier saturation rivers supersaturated and, thus, has potential scale.
