Abstract Groundwater provides much of the water used globally for irrigation and human consumption is central to One Health framework. Healthy groundwater depends on self-purification processes performed by diverse biota, but these can be threatened effects irrigation. In present article, we explore this threat using an interdisciplinary framework propose recommendations sustainable We identified two major potentially harmful ecosystems: habitat loss from lowering tables irrigation-induced leaching contaminants into groundwater. These mitigated improving technological practices, crop selection, use natural small retention measures, precision irrigation, controlled agrochemicals. The construction operation systems should consider hydrogeological conditions. recommend prioritizing biomonitoring at abstraction sites, considering different aquifer types, implementing advanced methods identify multiple contamination sources.

Abstract Aliphatic chlorinated hydrocarbons, notably tetrachloroethylene (also known as perchloroethylene [PCE]), are persistent, mobile, and toxic (PMT) and/or very (vPMT) groundwater pollutants, often exceeding safe drinking water thresholds. The present study delves into the risk assessment of PCE with a novel focus on sensitivity stygobitic species—organisms uniquely adapted to environments. Through comparative analysis subchronic effects locomotion behavior two copepod species, Moraria sp. nonstygobitic Bryocamptus zschokkei , we highlighted inadequacy current European predicted‐no‐effect concentration for ecosystems. Our findings indicate significant behavioral impairments in both species at (32 ng/L PCE) well below threshold deemed safe, suggesting that guidelines may not adequately protect unique biodiversity habitats.

Abstract Barium (Ba) dissolution and mobilization in groundwater are predominantly controlled by sulfate because of the low solubility barium (BaSO 4 ) minerals. Naturally present at concentrations groundwater, elevated Ba can occur as a result anthropogenic activities, including use barite drill operations, geogenic sources such leaching from geological formations. No toxicity data exist for with organisms (stygofauna) to assess risk concentrations. The study measured two stygobiont Cyclopoida species: one collected Wellington other Somersby, New South Wales, Australia. Toxicity was cyclopoid survival over 2, 4, 7, 14, 21, 28 days waters varying concentration (<1–100 mg SO /L). When present, dissolved decreased rapidly test solutions forming BaSO precipitate until depleted. excess remained form. cyclopoids clearly attributed Ba. Precipitated not toxic species. values Somersby species included (21‐day) no‐effect 3.3 mg/L an effective cause 5% mortality 4.8 (at 21 days).
