Question:
EPA sets the standard of zero
colonies of fecal coliform bacteria per 100ml of water to determine the possible presence of other disease causing bacteria, viruses, and protozoans that live in human and animal digestive systems.
Water Contaminated with the fecal coliform indicator bactiera must be treated and disinfected before ingestion to prevent intestinal diseases.
The microorganisms that are of highest concern include Cryptosporidium parvum, Giardia duodenalis, Campylocbacter spp., Salmonella spp., pathogenic strains of E. coli, and Yersinia spp.
What are some of the methods used to treat and
disinfect water containing these organisms?
Replies:
The methods used to treat contaminated water depend on
the source (wells, pits) use and quantitiy. You'll
find the answer to your question in a display from the
University of Missouri, which is included in the
Virtual Museum of Bacteria (www.bacteriamuseum.org).
