Water Quality- Coliforms

Ohio Department of Health (ODOH) regulates private water systems. Private water systems are considered “private” when they offer water to fewer than fifteen service connections; and they do not regularly provide water to more than twenty five people in a sixty day period. Private water systems include everything from springs, ponds, water storage tanks to wells and cisterns.  These systems give water supply to things like toilet flushing and laundry machines. ODOH private water systems program gives instruction and training on the construction and maintenance work these water systems need to operate properly. 


It also investigates if there is contamination in the water, and what might be in that water. E. coli is a popular water contaminator, because the pipes that run clean water run very close to the pipes that run sewage water. If one of those pipes were to break, the water would quickly become contaminated with E. coli or coliforms.  A coliform is a gram negative, facultative anaerobe that grows and lives in soils, plants, and in the intestines of humans and animals. Coliform aids in the digestion of food.
E. coli is a type of fecal coliform. It’s an easy indicator of water contamination because it does not live in wet areas for a long time.  E. coli 0157 has been in the news for its potentially dangerous outbreaks, and its associated illnesses. For example, E. coli 0157 has been spoken about in regards to Haiti, with all of the destruction in Haiti, there is a lot of E. coli illness outbreaks. You can contract E. coli contamination by drinking contaminated water or eating contaminated food. You will not always become ill from it, but if E. coli is present in your water, there may be other contaminants in it too. E coli causes diarrheal infections and urinary tract infections.  



Properly constructed underground drinking water systems should not have contamination problems. There should be 0ppm coliform bacteria when the water is tested. If you use cisterns, springs or ponds as a drinking water source, you should have treatment devices disinfecting the water.
