Addressing Legionella: Public Health Enemy #1 in US Water Systems
Steve Hubbs, PE

As the global community marks World Water Week, August 31- September 5, Steve Hubbs, former water treatment facility operator at the Louisville Water Company, provides his perspective on the most significant public health risk currently associated with US drinking water.

The United States has one of the safest drinking water supplies in the world, thanks to the steadfast efforts of thousands of water treatment professionals. The men and women of the water treatment industry implement technologies 24/7 that protect us from former waterborne killers like typhoid fever, cholera and hepatitis A.  With those enemies held at bay, what, you may ask, is the greatest microbial threat lurking in US tap water today?  The answer is the bacterium Legionella, public health enemy #1 in US water systems, posing a particular risk to hospital patients. Controlling Legionella will take some novel approaches and regulatory adjustments.

Chikungunya in the States
A Guest Article by Sabrina Jacobson


Have you heard about the Chikungunya virus? Although it is rarely fatal, its symptoms include fever and severe joint pain. Originally only present in countries in Asia, Europe, and Africa, it is gaining a presence in the United States after being carried to the Caribbean.  Starting in late 2013, a few Carribbean vacationers contracted Chikungunya, but the number of cases there has increased exponentially. This article will update you on what is happening with Chikungunya in the US since the Water Quality & Health Council’s first report on the virus.

Recently St. Lucie County health officials in Florida have been going door-to-door in order to warn citizens about the spread of the Chikungunya virus. Why should they warn people of this virus that has previously only existed as imported cases? If people contacted this virus only by vacationing in the tropics, why would we need to warn local … READ MORE >>


Cleaning up Safely after Flooding
Joan B. Rose, PhD

Cleaning up Safely after FloodingTorrential rainfall in the Midwest and Northeast US this week led to flash flooding, filling basements with water and sewage, which can contain hundreds of pathogens.  Residents should assume flood waters are contaminated and that exposure to these waters may raise the risk of diarrhea, dysentery, even hepatitis, skin and eye infections and respiratory disorders.

The first step in the cleanup operation is to remove flood water and sewage and dry the affected area.  Powerful fans and enhanced ventilation are helpful for drying damp structural surfaces.  Meanwhile, it is important to evaluate items contacted by flood waters, deciding what to discard and what to keep.  Whenever possible, a disinfecting solution of water and chlorine bleach should be applied to affected surfaces of saved items.

To help prevent disease transmission associated with flood cleanup, the Water Quality and Health Council offers the following tips:

Ebola: What You Should Know
Ralph Morris, MD, MPH

The deadly Ebola virus is on the move in the West African nations of Guinea, Sierra Leone, Liberia and Nigeria (see outbreak map.)  As of August 7, CDC reports the outbreak has infected over 1,700 people and claimed the lives of more than 900.  Ebola Hemorrhagic Fever – the formal name of the disease – first appeared in 1976 in Sudan and the Democratic Republic of Congo. The virus was introduced to humans through close contact with the organs, blood, and other bodily fluids of infected animals, such as chimpanzees, gorillas, fruit bats and monkeys. 

Ebola has closed schools in Liberia and prompted the president of Sierra Leone to quarantine affected neighborhoods and conduct house to house searches for people who might have been exposed to the virus.  What should you know about Ebola?

Important Facts about Ebola1

  • Ebola becomes contagious only when symptoms appear in infected people.
