Summary: Here, we present a protocol for inoculating drinking water samples with a variety of pathogens or facultative pathogen bacteria. We describe steps for preparing bacterial solutions, inoculating mineral water bottles and other drinking water samples, filtration and incubation of the agar plates, and counting colony-forming unit per mL. We also detail procedures for determining selected chemical properties, such as anions and cations, which can also affect the bacterial growth.For complete details on the use and execution of this protocol, please refer to Schalli et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
