Coliform in well water?
Coliform in well water is the presence of fecal matter in the well water. If the bacteria is found in drinking water, appropriate action needs to be taken.
Coliforms are rod shaped gram negative bacteria that are often in well water. Not all coliform are harmful, but those of fecal origin are very harmful. The lab coliform count determines what type and how many coliform are in a water sample. This result is always marked "fit for human use" or "NOT fit for human use".
This varies from country to country and possibly even states in US. However in general, drinking water must have NO coliform at all - that is called '0/100ml' Swimming pool water is generally allowed '200/100ml'. Anything other than that is 'high' . In general terms coliform is in almost every pool of water and in almost every well. What we are most concerned about is E coli , which is fecal coliform and is dangerous…
Yes, farm animals have coliform bacteria in their intestines just like humans do, and these bacteria are passed in the feces. If it gets into a well, the feces can contaminate the well. Because many of the bacteria can cause illness in humans, most water quality tests do not perform further testing to determine what the likely source of the contamination is.
Coliforms represent normal bacterial flora found in the intestines of humans and animals. Examples of coliform found in water include: Enterotoxigenic E. coli (Gram negative bacterium) which causes traveler's diarrhea Shigella spp. (Gram negative bacterium) which causes bacillary dysentery Vibrio cholerae (Gram negative bacterium) which causes cholera Salmonella enterica typhi (Gram negative bacterium) which causes typhoid fever
There are many kinds of bacteria that can grow on a water fountain, such as Pseudomonas and Coliform. However, there are things you can do to prevent bacteria growth. Filter systems, chemical coatings and ultra-violet light systems are available on many modern water fountains to inhibit bacteria growth.
