Each report is an accredited lab's microbiology analysis of bottled water samples. Counts are in CFU (colony-forming units): colony counts at 22/30/36 °C measure general bacterial load, while E. coli, coliforms, enterococci and Pseudomonas are hygiene indicators with zero tolerance — any detection turns the sample red.
Green = within limits, amber = above the warning threshold, red = above the legal/internal maximum.
