Water sampling is a methodological process for collecting representative portions of aqueous systems (e.g., surface water, groundwater, wastewater) for subsequent physicochemical, biological, or isotopic analysis. Method design incorporates sampling objectives, spatial and temporal resolution, and analyte stability, and may use grab, composite, depth-integrated, or automated sampling strategies. Protocols specify container materials, preservation (e.g., acidification, cooling, filtration), contamination control, and chain-of-custody procedures. Hydrodynamic conditions, stratification, and phase partitioning (dissolved, colloidal, particulate) are explicitly considered to avoid bias. Rigorous field documentation, decontamination, and quality assurance/quality control (QA/QC) safeguards ensure data comparability, traceability, and statistical validity for environmental monitoring and research.
Antimicrobial resistance (AMR) is defined as the ability of disease-causing microorganisms to withstand treatments like antibiotics.
