Day 17: Enteroviruses

Enteroviruses have been shown to occur in high concentrations in untreated and treated water sources.  They are one of the most common causes of human infections, responsible for over 30 million infections in the US every year.  Because enteroviruses are highly resistant to both uv disinfection and chlorination, they are one of the most difficult contaminants to detect and remove from water.  There is no acceptable level of enteroviruses, however because they are not easily detected, they are generally controlled by strict treatment protocols.

History:
It has only been in recent years that treatment and testing guidelines have revealed enteroviruses as a weak spot in how drinking water systems are managed.  Since enteroviruses do not respond to antibiotics, are resistant to disinfection methods, and very difficult to detect, they have more recently been used as strong evidence to promote the use of advanced filtration methods using nano-filters and reverse osmosis.
