Chemical analyses of an extensive dataset of water samples revealed that they exhibit a Ca-HCO<sub>3</sub> composition with a relatively low Total Dissolved Solids (TDS < 400 mg/L), suggesting limited interaction with the surrounding carbonates and silicates, and short and shallow pathways. A few samples show SO<sub>4</sub>-enrichments and higher TDS (up to 3350 mg/L), likely related to relatively deep flow paths interacting with the evaporitic Triassic Burano formation, while the presence of some Na-HCO<sub>3</sub> (TDS up to 1000 mg/L) waters suggests prolonged circulation within Na-rich terrigenous formations.</div><div>The Chemical Water Quality Index (CWQI) confirms that most NCCR waters are qualitatively good since the anthropogenic contamination is practically negligible, as testified by the low contents of nitrate and chloride.

This review investigates how different biopesticides, such as microbial agents, biochemical compounds, and plant-incorporated protectants, affect the gut microbiota and intestinal health of freshwater fish. The gut microbiome plays a vital role in digestion, nutrient absorption, immunity, and overall fish health. Biopesticide exposure may disrupt microbial balance, leading to reduced diversity, changes in community composition, inflammation, and dysbiosis. These alterations can impair digestive efficiency, immune function, growth, and reproduction. Promising mitigation strategies include the use of probiotics, prebiotics, symbiotics, insect-based feeds and other non-bacterial dietary interventions to restore gut homeostasis and improve fish resilience. In addition, advanced techniques like metagenomics and metabolomics are enhancing our understanding of host–microbiome interactions under biopesticide exposure. This review emphasizes the importance of including gut microbiota health in environmental risk assessments for biopesticide use in aquaculture.

The total mass and distribution of all individual detectable PFASs in the source zone was determined from the compiled data set, which included 28 soil borings with multi-depth PFAS samples, 17 porous cup suction lysimeters sampled 3 times over 8 months, and 8 shallow groundwater wells sampled 3 times over 8 months. PFAS analyses consisted of both target (quantified) and suspect (semi-quantified) analytes. Results showed that PFASs varied in their vertical and horizontal distribution within the FTA, and that a majority of the zwitterionic and cationic precursors were retained in shallow soils. While perfluoroalkyl acid (PFAA) precursors comprised 61 % the PFASs in collected soil sample, PFAAs were by far the dominant PFAS class within both porewater and near downgradient groundwater (78 % and 87 %, respectively). PFAS porewater concentrations generally increased with increasing soil moisture content, and these increases were reasonably described for perfluorooctane sulfonate (PFOS) by an equilibrium-based mass balance model that accounted for PFAS accumulation at the air-water interface and soil-water partitioning. PFAS porewater concentrations located within or adjacent to low permeability soils showed greater increases with moisture content than in porewater associated with sandy materials, likely due to the larger role of air-water interfacial area in PFAS phase distribution in these fine-grained soils. Bench-scale batch desorption tests conducted with site material reveal a significant PFAS mass that is not readily desorbed from the soil. Observed K<sub>d</sub> values measured in the field are comparable to the bench-scale data if this desorption-resistant PFAS mass is considered.
