WATERBORNE PATHOGENS - EPA EXCERPT
Below is an excerpt from the EPA (Environmental Protection Agency) explaining the differences in bacteria, viruses
and cysts (protozoa) and the types of waterborne diseases they are associated with.
Microorganisms Associated with Waterborne Disease
The following groups of microorganisms have been linked with the occurrence of waterborne disease. As each
pathogen is isolated and identified as a threat to water quality, ORD (Office of Research and Development)
researchers try to discover the most effective combination of barriers and disinfection methods to minimize risk of
human exposure.
Bacteria. Bacteria are the most widely distributed life forms. Pathogenic bacteria
range in length from approximately [400 nanometers to 14,000 nanometers]
and [200 nanometers to 1,200 nanometers] in width. Key bacterial pathogens
responsible for waterborne disease include Legionella, Salmonella typhi, Shigella,
and Vibrio cholerae.
Viruses. Viruses are inactive when outside of a living host cell. Viruses linked to
waterborne disease have protein coats that provide protection from environmental
hazards and range in size from [20 nanometers to 90 nanometers]. Unlike
bacteria and protozoa, they contain only one type of nucleic acid (RNA or DNA).
Key pathogens include hepatitis A and Norwalk virus.
Protozoa. Protozoa, common in bodies of water, are much larger than bacteria
and viruses. To survive harsh environmental conditions, some species can
secrete a protective covering and form a resting stage called a “cyst.” Encystment
can protect protozoa from drinking water disinfection efforts and facilitate the
spread of disease. Key protozoa being studied as agents of waterborne disease
include Giardia and Cryptosporidium [4,000 nanometers to 15,000 nanometers ].

Minimum of volume (gallons) of dechlorinated tap water passed through each filter. The flow rate was maintained at
approximately 1-1.3 gallon/minute at a pressure of 50-60 PSI. Ten liters of deionized lab grade water was seeded
with the indicated microorganisms and passed through the filter at a flow rate of 1.0-1.2 gallon/minute at each
of the test points indicated. Filter influent and effluent following the passage was collected and assayed for the
respective microorganisms.
The following are some common microorganisms that form part of the group of bacteria and viruses and the diseases
they are related to:

The received bottles unit was conditioned by soaking the filter in General Test Water 1 (GTW1(NSF P231), Dechlorinated Municipal water) and then aspirating
1-Liter at a flow rate of 400 mL/min using a peristaltic pump as per NSF guidance. Silicone tubing was connected to a programmable peristaltic pump and
was placed onto the mouth suction tab of the bottle. The entirety of the bottle unit was submerged in the GTW1 (the bottom of the bottle was unscrewed and
a vent hole was placed into the upper side of the plastic bottle about 1" below the threadline to facilitate bottle filling and submersion, additionally one was
also placed in the bottom of the bottle). The pump was activated and the flow rate gradually was increased from 100 mL/min to 400 mL/min. The line vacuum
was measured continuously and did not exceed 1.0 PSI. For the challenge, aliquots of R. terrigena (RT) culture and MS-2 virus were added to GTW1 and the
water was homogenized. A sample of the challenge water was removed and enumerated for the respective microorganisms prior to challenge initiation. 500ml
of challenge water was aspirated through the unit at a flowrate of 400mL/min and the resulting vacuum. During the challenge the water level was maintained
at height below the top orifice of the filter unit; this was done to eliminate the possibility of the challenge water bypassing the filter unit. Following the initial
challenge, the bottle unit was submerged in GTW1 and 600L was aspirated through the unit at 400mL per minute. Following 800L, 1200L and 1600L, the
challenge was repeated. The line vacuum was monitored and did increase above what was initially measured at the lower flow rate. For each of the challenge
events, the unit's collected influent and effluent samples were analyzed in duplicates at two dilutions at the minimum as per standard lab operating procedure.
