What is Legionnaires’ Disease?

In the fall of 2017, an outbreak of harmful bacteria linked to the cooling mist at Disneyland in California caused 22 people to develop Legionnaires’ disease, resulting in one fatality. In December of 2018, a health official testified that Legionella bacteria in the water of the cooling tower was the most likely source. This frightening outbreak left many people seeking more information about just what Legionnaires’ disease is and how it is caused. Our goal is to help you understand Legionnaires’ disease and its causes, as well as how we can help if you suspect contamination of this bacteria.

Where Does Legionnaires’ Come From?

The Legionella bacteria is typically found in bodies of freshwater such as lakes, streams or rivers. It only becomes a health concern if found in large quantities within these systems or if it is found in man-made water systems such as hot tubs, sink faucets, air conditioning systems, fountains, water features, or hot water tanks. Legionella bacteria can cause health issues to humans once it is in the form of water vapor. Once it enters the water vapor, it can be inhaled by humans which can potentially lead to legionellosis. In more rare cases, Legionella have been transmitted to the lungs from drinking water. This happens when an individual aspirates on drinking water and typically only occurs in individuals who have difficulty swallowing.

What is The Difference Between Carbon Black and Soot?

When we think of combustion engines and the pollutants they produce, we typically picture cars and trucks driving along the interstate. In fact, we rarely think that there would be contamination from these combustion processes inside of our homes and businesses. If you’ve ever noticed a black stain on your carpet, around your wall outlets, or near ventilation grates, you may have a carbon black or soot problem on your hands. Carbon black and soot can both pose a significant risk to the health of you and your family if left undetected and untreated.

Carbon Black

According to the United States Environmental Protection Agency, carbon black is a black residue that results from the incomplete combustion of hydrocarbon fuel such as oil or gas with a limited supply of combustion air and high temperatures. In the United States, carbon black is manufactured as a binding agent in rubber (specifically tires) and for use in household products with functions such as pigmentation, ultraviolet (UV) stabilization and use as a conductive agent. Carbon black can be found in black printing inks, paper, plastics, and surface coatings. It appears as a fluffy, highly pigmented, black powder. Because of its close physical and chemical similarity to soot, carbon black is thought to be carcinogenic and can possibly pose a risk to your health if inhaled. It is almost identical to soot in composition but contains more carbon as a result of its manufacturing process.

Air-O-Cell® Cassettes: What Are They Used For?

When discussing air testing, the first question many people have is “how are samples collected?” While many people picture collecting a sample of air in a jar or some other simple container, the actual process is much more efficient than that. All in all, air samples typically require a filtration process in which the air is pushed through a filter or slide and the contents of the filter/slide are then analyzed for particulate matter and contaminants. That’s exactly why we use Air-O-Cell® Cassettes.

Air-O-Cell® Cassettes are manufactured by Zefon International and are basically miniature air filtration chambers that catch air contaminants on a small slide for microscopic analysis. Contaminant-laden air is pushed through an inlet slit using an air pump and directed toward the slide. The air passes through the chamber, leaving particles behind on the slide and passing out of the other side of the chamber. This slide can then be extracted from the cassette and analyzed directly underneath a microscope for particles and contaminants.

Why It’s Important to Monitor the Quality of Water

Quality drinking water is essential for our health and well-being. Testing water quality is important for municipalities, businesses, and homeowners. Whether water is used for drinking or irrigation, it’s vital that water quality is monitored regularly so that any problems can be addressed in a timely manner.
In this article, you will learn about common water contaminants and why it’s important to contact commercial laboratories for regular testing of water quality.

What are the most common contaminants in the United States?

According to the Centers for Disease Control and Prevention (CDC), common contaminants can be biological, pathogenic, chemical and mineral. Below, we will discuss some of the most common contaminants and the impact they have on individuals who ingest them.

What Affects the Quality of Our Drinking Water?

Water quality is essential to good health. Poor water quality can lead to various diseases. According to Centers for Disease Control and Prevention (CDC), some of the most common causes of public water system contamination outbreaks in the U.S. are Giargia, Legionella, Norovirus, Shigella, Copper, E. coli and Salmonella. The presence of these contaminants can lead to serious health problems including gastrointestinal disorders. That’s why it’s essential to perform routine, comprehensive water testing to ensure quality drinking water resources that is free of any contaminants.

But what are the factors that affect the quality of drinking water? What factors degrade the water quality? Below, we will discuss the answers to those questions and more.
