EPA and the Water Quality Professionals in the sewage industry don't  want you to know what type of
pathogens may be in your drinking water, reclaimed water, or biosolids. These water quality
professionals would rather you didn't know E. coli is the fecal coliform as well as one of the gram
negative coliform bacteria, all of which are pathogenic disease causing organisms.

Human health effects showing up as pandemics

EPA only discusses:
Coliform bacteria are common in the environment and are generally not harmful. However, the presence of
these bacteria in drinking water is usually a result of a problem with the treatment system or the pipes which
distribute water, and indicates that the water may be contaminated with germs that can cause disease.

Fecal Coliform and E coli are bacteria whose presence indicates that the water may be contaminated with
human or animal wastes. Microbes in these wastes can cause short-term effects, such as diarrhea, cramps,
nausea, headaches, or other symptoms.

Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for
microbial growth. Turbidity may indicate the presence of disease causing organisms. These organisms include
bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated
headaches.

Cryptosporidium is a parasite that enters lakes and rivers through sewage and animal waste. It causes
cryptosporidiosis, a mild gastrointestinal disease. However, the disease can be severe or fatal for people with
severely weakened immune systems. EPA and CDC have prepared advice for those with
severely compromised
immune systems who are concerned about Cryptosporidium.

Giardia lamblia is a parasite that enters lakes and rivers through sewage and animal waste. It causes
gastrointestinal illness (e.g. diarrhea, vomiting, cramps).
