The proliferation of cyanobacteria has become a significant water management challenge due to the increasing eutrophication of water supply reservoirs. Cyanobacterial blooms thrive on elevated nutrient concentrations and form extensive green mats, disrupting the local ecosystem. Furthermore, many cyanobacterial species can produce toxins that are lethal to vertebrates called cyanotoxins.

This article highlights the infection control risks associated with water sources and the regulatory requirements for water management plans in health care facilities. The guidance on water quality has evolved from the initial technical information report provided by the Association for the Advancement of Medical Instrumentation in 2014 to the more recent 2023 publication of the American National Standards Institute and Association for the Advancement of Medical Instrumentation standard for water used in medical device processing.

Humic acid (HA) enhances colloidal transport in porous media, yet the mechanisms by which the HA adsorption conformation affects colloid transport remain unclear. This study investigated the influence of HA on the transport of petroleum-hydrocarbon-contaminated soil colloids (TPHs-SC) in saturated sand columns. The presence of TPHs on the colloidal surface occupied adsorption sites, hindering HA from forming a horizontal adsorption conformation, as observed on uncontaminated soil colloids (SC).
