The global spread of glyphosate (GLY) via agricultural runoff poses a significant threat to ecosystems, human health, and the environment, underscoring the need for sustainable agricultural practices. A comprehensive study on glyphosate contamination in runoff water, flowing surface waters, groundwater-influenced, and stagnant water samples was conducted from 2019 to 2021, across a diverse range of landscape types and environmental zones. This research constitutes a novel contribution to the field, focused on several distinct regions, including agricultural regions, tourist zones, and ecologically sensitive areas, including the Beka Natura Reserve, Natura 2000 sites and the Coastal Landscape Park in Poland. Glyphosate residues, with a maximum concentration range of 43.0–8406 ng/L, were detected in 63.5% of water samples collected from protected and unprotected areas. Glyphosate concentrations in water at high-tourism areas were highest in runoff samples from recreational and protected areas, including the Czarna Wda River in Ostrowo (512 ± 9.91 ng/L). Investigated water samples showed target hazard quotient values for glyphosate < 1, indicating no human health risk, and risk quotient values for GLY < 0.1, indicating a low ecotoxicological risk. The presented study is aligned with the United Nations’ 2030 Agenda for Sustainable Development, aiming to contribute to global sustainability goals.
