The conclusions of the analysis are categorical: "All control samples, whether the reserve samples, the positive and negative analytical controls, as well as the negative control taken before the introduction of the elements, demonstrated compliant and acceptable results." Even effluent samples enriched with MS2 and R. terrigena, subjected to a two-phase evaluation, generated remarkably similar results. This consistency strongly suggests that no active antimicrobial agents are released into the treated water.
In short, silver proves to be a natural protector within Black Berkey® elements, guaranteeing flawless self-disinfection and water purification that meets the highest quality standards.
