“…Phosphogypsum is most often discharged to superficial water objects (Bezsonnyi, 2021) without any known consequences or is dumped on open grounds, leading to serious environmental pollutions. There are reports demonstrating that recycling of phosphogypsum as a road construction material is safe and causes no pollution of groundwater and has no radiological impact (Amrani, 2020).…”

The problem of recycling and storage of phosphogypsum is relevant for many coun- tries of the world, as it is associated with environmental problems such as pollution of water bodies, soil and atmosphere. This study analyzes the possibility of using phosphogypsum for the construction of roads. The objective was a geoecological analysis of the danger of phos-phogypsum stockpiles and a study of the possibility of using phosphogypsum in road construction to solve the problem of its accumulation in the environment. The chemical composition of phosphogypsum samples of the Sumyhimprom and Rivneazot companies was studied using the method of X-ray diffractometry. The content of heavy metals (HM) was analyzed using atomic absorption spectros-copy. An extremely high level of chromium was determined, accounting for more than 20-33 Maximum Concentration Values (MCV). The content of cuprum in the phosphogypsum samples of Rivneazot was 2 MCVs. The contents of other heavy metals did not exceed the MCVs, the synergistic effect should be taken into account. Migration of heavy metals is one of the main problems associated with phosphogypsum stockpiles. The increased acidity of phosphogypsum promotes the formation of soluble HM compounds. Depending on the solubility of toxicants, they accumulate in the ecosystem or migrate, dissolve, and enter plants. The traditional methods of storing phosphogypsum, both from an environmental and economic points of view, are less acceptable than the methods of its recycling and reuse in various sectors of the national economy. The paper theoretically substantiates that the reuse of accumulated phosphogypsum and the implementation of new technological solutions in road construction would reduce the level of technogenic loading that phos- phogypsum imposes on the environment. Based on the analysis of the content of heavy metals and the development of concentration logarithmic diagrams, mobile forms of metals were studied and the harmful effect of metals leaching from phosphogypsum was considered. We determined the positions of toxic substances in the engineering road construction – environment. We recommended dividing hydroxides and hydroxocomplexes of heavy and toxic metals into three groups according to their solubility, having the ability to migrate in acidic, neutral and alkaline environments, respectively. Strict regulations are needed to protect soil cover in areas with acidic soils. We grouped soils on which it is not recommended to use engineered road structures with phosphohypsum due to increased migration of HMs into the ecosystem: sandy; soils rich in humus components, acidic soils (sod-podzolic) or in case of existing proba- bility of an increase in soil acidity (unorganized ingress of industrial waste, acid rain, etc.); acidic soils salinized with chlorides; soils containing ammonia; soils containing sulfates.

Safe drinking water is a basic requirement for good health. Fresh water is already a limited resource in many parts of the world. In the next century, it will become even more limited due to population growth, urbanization and climate change. Purpose. Provide a comprehensive assessment of the water quality of the Kaniv Reservoir based on the calculation of the Water Quality Index (WQI). Methods. Analytical-synthetic method, geo-information (cartographic modeling), analysis of information sources, mathematical modeling. Results. There is an increase in BOD, COD and dissolved oxygen content in the area of the Kaniv Reservoir from the hydropost 500 m above the Bortnytsky Aeration Station (BAS) to the hydropost 2 km below the Kanivska Hydropower Station’s dam. The only exception is the hydropost 500 m below the BAS, for which the corresponding values are the largest, and the BOD indicator exceeds the established standards by 1.5 times. Ammonium content 500 m below BAS exceeds the standards established by Directive 98/83/EC by almost 3 times. Exceeding the normative values for the content of sulfates and chlorides and suspended substances were not recorded. The least polluted water is observed at hydrostations located below Ukrainka and Pereyaslav-Khmelnytskyi. The highest value of the water quality index is 242, which is typical for the hydropost 500 m above the BAS and corresponds to the value of the worst quality. Conclusions. It was in the immediate vicinity of the city of Kyiv that the water turned out to be the most polluted. This may indicate the imperfection of industrial, domestic and agricultural wastewater treatment systems. For the hydropost 500 m below the BAS, excesses of the normative values for the parameters of ammonium and BOD content were also recorded, while other parameters are either at the limit of the norm or approaching it. Studies of the water quality of the Kaniv Reservoir showed that its quality according to the WQI indicator varies from 59 to 242 (from low to the worst). Accordingly, such water, in the absence of another source, can be used for drinking after passing proper multi-stage purification.

Purpose. Provide an assessment of the quality of the massif of surface waters of the Siverskyi Donets River within the Kharkiv region in 2023 based on the determination of water quality indices. Methods. The methods of the modified water pollution index (WPI) and the combinatorial water pollution index (CWPI). Results. State of the river water at the observation point of the v. Pechenigy according to the method of the modified water pollution index WPIF is estimated as II class characterized as "clean", WPIH - I class, "very clean"; according to the method of the combinatorial index of water pollution CWPIF - class III a, "dirty", CWPIH - class I, "slightly polluted". State of the river water at the observation point of the v. Eschar according to the method of the modified water pollution index of WPIF is estimated as III class characterized as "moderately polluted", WPIH - II class, "clean"; according to the method of the combinatorial index of water pollution CWPIF - class III b, "dirty", CWPIH - class II, "polluted". State of the river water at the observation point of the v/ Zadonetskyi according to the method of the modified index of water pollution, WPIF is estimated as III class characterized as "moderately polluted", WPIH is II class, "clean"; according to the method of the combinatorial index of water pollution CWPIF - class III b, "dirty", CWPIH - class I, "slightly polluted". Conclusions. It was determined that there are changes in water quality along the watercourse of the Siverskyi Donets River within the Kharkiv Region in 2023. There is a deterioration of water quality after the confluence of the Uda River, by 1.69 times the magnitude of the index change, then the state of water quality improves by 1.25 times the magnitude index changes, probably due to self-cleaning processes and lower anthropogenic load. The quality of water according to WPI indicators varies from 0.25 to 1.47 (from "very clean" to "moderately polluted"). The quality of water according to the CWPI indicators varies from 1.0 to 3.83 (from "slightly polluted" to "dirty"). It was established that according to both assessment methods and both standards, the quality of water in the Pechenigy reservoir, p. Pechenegs the best, and the worst water quality in the Siverskyi Donets River below the mouth of the Uda River, village Eschar.
