Legionella occurs naturally in the environment and is most commonly found in water. These bacteria thrive in warmer environments, so they are often found in hot tubs, hot water tanks, cooling towers, larger plumbing systems and decorative fountains.
Proper testing & maintenance help prevent deadly Legionella outbreaks
On the shores of Lake Victoria in Uganda there is a rural community called Maruba. Rain is rare, so the people of Maruba used to rely on the lake as their only source of freshwater. Unfortunately, it was teeming with microbiological contaminants that cause waterborne diseases such as schistosomiasis, dysentery and diarrhea. The water was further contaminated by pesticides used by local farmers to treat crops. Rain would wash these harmful chemicals into the lake.

Clearitas removes scale, kills bacteria, reduces chlorine demand in utility and commercial water systems
The U.S. Patent and Trademark Office has awarded U.S. Patent 8,518,270 directed to methods encompassing use of the Blue Earth Labs’ Clearitas (formerly RE-Ox) scale-control solution. This patent, the 10th one held or acquired by the company, broadens the exclusive rights obtained by the previously granted U.S.
Reading the Centers for Disease Control and Prevention’s (CDC) Web pages on recreational water illnesses (RWIs) is enough to make someone never want set foot in a swimming pool again. From the list of pathogens that can cause RWIs (which includes some nasty fellows, such as Cryptosporidium, Legionella, E. coli and more) to statistics on sources of disease (“on average, people have about 0.14 grams of feces on their bottoms”), the cringe factor is high.
The Legionella bacterium, Legionella pneumophila — the fundamental agent of Legionnaires’ disease — is a water-based organism that causes infection when inhaled in aerosol form. Legionnaires’ disease acquired its name in 1976, when an outbreak of pneumonia occurred among attendees of a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness was named Legionella.

Update includes setting a limit for E. coli to better protect public health
The U.S. Environmental Protection Agency (EPA) has updated the rule for pathogens in drinking water, including setting a limit for E. coli to better protect public health.
The Revised Total Coliform Rule ensures that all of the approximately 155,000 public water systems in the U.S., which provide drinking water to more than 310 million people, take steps to prevent exposure to pathogens like E. coli. These types of pathogens can cause a variety of illnesses, with symptoms such as acute abdominal discomfort or, in more extreme cases, kidney failure or hepatitis.
New awards recognize influential researchers and subscribing utilities for contributions to advancing science of water
At its annual Subscriber Breakfast on June 11, the Water Research Foundation announced the inaugural winners of two new award programs. The Research Innovation Award honors researchers and research teams who have made significant contributions to advancing the science of water through foundation-sponsored research. The Outstanding Subscriber Award for Applied Research honors subscribing utilities that have made notable improvements to their treatment, delivery and/or management processes through the successful application of foundation research.
Approximately 6,000 public water systems will begin monitoring 28 chemicals and two viruses beginning in 2013
The U.S. Environmental Protection Agency (EPA) recently published a list of 28 chemicals and two viruses that approximately 6,000 public water systems will monitor from 2013 to 2015 as part of the agency’s unregulated contaminant monitoring program.
The program collects data for contaminants suspected to be present in drinking water but that do not have health-based standards set under the Safe Drinking Water Act.
Newly published research paper demonstrates test inaccuracies due to sample holding time
Water management services company Phigenics LLC recently announced the publication of a research paper that demonstrates up to 33% false-positive test results for Legionella bacteria when following conventional sampling methods.
What exactly is final barrier? How does it work? Where does it fit into my business? These are questions asked by many dealers in the water treatment industry. The WQA Aquatech USA 2012 tradeshow, held March 6 to 9, focused on these questions with a mixture of presentations and a focus group discussion.
