Water resources are closely linked to human productivity and life. Owing to the deteriorating water resources environment, accurate and rapid determination of the main water quality parameters has become a current research hotspot. Ultraviolet-visible (UV-Vis) spectroscopy offers an effective tool for qualitative analysis and quantitative detection of contaminants in a water environment. This review aimed to investigate and detect groundwater contamination via optical properties in west Berbar (Younis area (A and B), Gadalla (E), Alhalfa wadalfaki Ali (D), and Atbara area (C). The optical properties (absorption coefficient, reflection, refractive index, and extinction coefficient) of the contaminated water were obtained. The samples were analyzed using UV, ICP, XRD, pH meter, and conductivity meter. The result showed that there is no heavy metal with ICP spectroscopy, even though there is silicon in all samples that confirms UV. All optical properties in the IR region, TDS, pH, and EC showed that they were higher than the WHO (2008) standard; the optical properties for all samples (E, B, A, C, and D) matched with the pH, TDS, EC, and sodium concentration. Finally, the future development of UV-Vis spectroscopy for the determination of water quality was discussed. Therefore, it recommends the government and other responsible authorities take appropriate corrective measures.
