Dnipro Reservoir water-quality and environmental-risk data, Ukraine, 2003–2022

This dataset supports the article “Integrated assessment of the surface source of water supply according to environmental-risk indicators”. The study concerns eight drinking-water monitoring checkpoints along the Dnipro Reservoir and adjacent Dnipro–Donbas Canal, Ukraine, and uses State Water Agency monitoring data for 2003–2022. The package contains two clearly separated evidence layers. First, it includes monthly 2020 measurements from seven checkpoints (p2–p8) extracted from the author-supplied calculation workbook. Second, it includes publication-derived averaged monitoring values for all eight checkpoints for 2003–2022, normative reference values, the ecological-risk classification scale, exact general-risk values explicitly stated in the article for p3 and p6, and the publication’s priority-contaminant ranking. The water-quality indicators are BOD5, suspended solids, dissolved oxygen, sulfate, chloride, ammonium nitrogen, nitrate nitrogen, nitrite nitrogen, phosphate, synthetic surfactants, and chemical oxygen demand (COD). The article identifies nitrites, nitrates, phosphates, and suspended solids as priority parameters. It reports an increase in general ecological risk from 0.999999206 at checkpoint p3, before Kamianske, to 0.999999924 at checkpoint p6, where the Dnipro River leaves the city of Dnipro. The original workbook is preserved unchanged. The supplied workbook does not contain the complete observation-level 2003–2022 database and has no monthly records for p1; therefore, the dataset does not claim full numerical reproduction of all risk-ranking figures from the workbook alone.
