Categories of Contaminants Chemicals  Organic  Inorganic Microbiological  Bacteria  Virus  Protozoa  Helminths Physical  Turbidity  Colour  Odor  Taste

“In 2007 we (Americans) spent $16 billion on bottled water. That’s more than we spent on iPods or movie tickets”

Size Comparison Virus (0.02 to 0.2 micron) Helminth 40 to 100 microns Pore size in a sand filter (1 micron) Smallest Largest Virus Bacteria Protozoa Helminth Bacteria (0.2 to 5 microns) Protozoa 4 to 20 microns
