• Abstract: The assessment of water quality is essential to ensure its suitability for different uses such as human consumption, irrigation, and livestock watering. Parameters such as electrical conductivity, pH, sodium, potassium, and coliforms allow the identification of chemical composition, salinity levels, acid-base balance, and the presence of microbiological contamination. These indicators are influenced by natural factors and especially by anthropogenic activities such as agricultural practices and wastewater discharge. The analytical process involves proper sample collection, sample preparation, the use of specific equipment, and systematic recording of results. In irrigation, the interpretation of results is based on standards and guidelines, allowing the evaluation of compliance and the identification of potential risks. Thus, water quality parameters provide essential support for public health, efficient agricultural management, and the sustainable administration of water resources.
