The formation of a groundwater aquifer in a unique territory disturbed by the quarrying of a phosphorite deposit in the southwest of the Leningrad region, built up with industrial facilities for ore processing, auxiliary production, and waste storage is considered. During the quarrying of the phosphorite layer, the hydrogeological section was disturbed, the filtration and capacitive properties of the soils of the aeration zone and water-bearing rocks changed. In the zone of active quarries, during dewatering, the forming depression funnel changes the direction of the natural watercourses of the Luga River basin, mixing of surface and underground waters and runoffs, filtered from the waste storage facilities for the production of mineral complex fertilizers On the territory of the mining complex, its own, special technogenic aquifer of groundwater is formed, characterized by high pollution and an increase in levels. During the reconstruction of the enterprise and the transition to imported raw materials, the dewatering in the quarries stopped, the depression funnel began to fill, supporting the unloading of the manufactured ground runoff from the territory of the enterprise, which caused flooding of the main waste storage facilities
