According to the Ministry of Agriculture, Barbados: “Microbiological testing is conducted on potable (bottled and public supply), waste, marine, and desalinated waters. Microbiological testing includes analyzing the presence/absence and enumeration of various microorganisms including: Total coliforms: These bacteria are commonly found in the intestines of warm-blooded animals or in the environment; for instance, soil, water, and grain. High coliform levels in water can serve to indicate poor sanitation and the possibility of other pathogens proliferating as the conditions for growth are similar. Fecal coliforms: Bacteria of fecal origin, whether animal or human, is used as an indicator of fecal contamination in water. This test can be used to detect any failure in water treatment. Fecal streptococci: Along with fecal coliforms, fecal streptococci also serves as an indicator of fecal contamination in water. Enterococci: The presence of enterococci serves as an indicator of fecal contamination in water. This analysis is primarily used to monitor the effectiveness of wastewater treatment plants and pollution of marine waters (beaches).”
