Legionella exposure poses a risk as schools reopen

As buildings continue to reopen during the coronavirus pandemic, the risk of legionella exposure remains, including in schools that have been closed for many months. Stagnant water, like that in buildings that have been closed for extended periods, provides an ideal environment for Legionella to grow. At least 10 schools in Pennsylvania and Ohio found harmful bacteria in their plumbing when attempting to reopen this fall. Schools often have many water use locations, from gym showers to drinking fountains, making them vulnerable to bacterial growth, including Legionella, when the systems aren’t cared for properly. However, water researchers note that most…

The Duty of a Maintenance Company

The next case we’re going to revisit, while also involving a hotel, is unique as it involved an external maintenance company and the duty it owed to keep a pool system safe. In this case, a hotel employee was tasked with manually cleaning out the filter for the pool and hot tub. Within a week, the employee began to feel ill and was later diagnosed with Legionnaires’ disease. He was the third case of Legionnaires’ disease that could be traced back to the hotel. He was hospitalized multiple times over a 5-month period as a result of his diagnosis. Both…

Seniors in Tazewell County Have More Than COVID-19 to Worry About

Four days ago, a third resident of UAW Senior Citizens Center in Pekin recently contracted Legionnaires’ Disease. Just within the last two months, a man in his 70s died from the disease and a woman recovered but was hospitalized. Tazewell County Health Department’s communications manager said that the Illinois Department of Public Health is working with the building management to mitigate the water issues. There have been 8 cases of diagnosed Legionnaires’ Disease in Tazewell, though the TCHD’s communications managers says the other five cases are unrelated to the UAW outbreak. On September 10, the TCHD issued a public health…

CDC Issues Updated Guidance for Reopening Buildings Following COVID-19 Shutdown

Earlier this year, the United States Centers for Disease Control and Prevention issued guidance for reopening buildings that have been closed due to the COVID-19 pandemic. Because Legionella bacteria is at an increased risk of growing in stagnant water, the CDC published a list of 8 steps business and building owners should take to minimize Legionella growth before opening, which included properly maintaining the building’s water heater to at least 140 Degrees Fahrenheit, cleaning all cooling towers of stagnant pools of water, and flushing out all faucets before use.[1] As of late September, the CDC has updated its guidance for…

Following the Flanders: Updating the HVAC System at Your Shore Hotel Complex Could Stay Legionella Growth

The Flanders Hotel in Ocean City, NJ recently completed more than $10 million in renovations, revamping almost every portion of the hotel and adding 21 new suits. But the expansion created major issues for the building’s HVAC system’s cooling towers: the old metal-clad tower struggled to provide adequate cooling for the expansion. To ensure comfort for their guests, the Flanders went about updating its cooling tower system. After many consultations with engineers, the hotel’s Director of Operations came across a metal tower alternative constructed out of high-density polyethylene (HDPE). Little did the Flanders know that this alternative would come with…

Legionella Amidst the COVID-19 Pandemic

For months, many businesses, buildings, and facilities have remained closed during the COVID-19 outbreak. The temporary shutdowns have likely resulted in a reduction of normal water use in the buildings, which can create dangerous conditions for returning occupants, as States are reopening their local economies. One microbial hazard businesses should consider when planning their reopening is Legionella. Legionella bacteria causes Legionnaires’ disease, a serious type of pneumonia. It is found naturally in freshwater environments, but can grow and multiply in common, human-made water systems like hot tubs, spas, showerheads, decorative fountains and water features, large plumbing systems, and cooling towers…

New York City Admits Still Does Not Know Where All Cooling Towers Are

New York City Council enacted a law in 2015 after a deadly outbreak of Legionnaires’ disease in the Bronx. The law requires that every cooling tower in New York City be identified, registered and inspected on a regular basis. The city has admitted recently that it is not sure it has found all cooling towers, three years after the legislation was passed (the city health department uses experts on the street and satellite imagery to find cooling towers). This failure to even identify all cooling towers takes on added significance after one remembers that there have been two recent outbreaks…

Cooling Towers as a Source of Legionnaires’ Disease

This office has had numerous inquiries regarding persons contracting Legionnaires’ disease. Often times the person does not know where they acquired the disease. Unfortunately, many times the person acquired the disease from a cooling tower. The cooling tower need not be in the vicinity of the person who acquired the disease, or even have been identified by health authorities. Consequently, the person may not know that a cooling tower has caused him or her to get sick. These cases are considered sporadic in nature. On the other hand, when a cooling tower has been identified as the source, as in…

Spas, Hot Tubs and Jacuzzis as source of Legionnaires’ disease

This office has handled many cases of Legionnaires’ disease acquired from a spa, hot tub or Jacuzzi. The recent outbreak in Hampton, New Hampshire is a case in point. One possible source of this outbreak is in the indoor spa at the Sands Resort in Hampton. The reasons a spa may be a source is due to the nature of the system supplying water to the spa. The system itself is called a closed loop system. This means that the water supplying the spa, hot tub or Jacuzzi is in a continuous loop closed off from other water systems in…

New York State Regulation of Legionella-A Real Step Forward

As promised, this blog will cover US legislative attempts to control the bacteria legionella that causes Legionnaires’ disease. While many states have requirements as to the amount of residual chlorine that must be present in spas, no state has legislation to curtail legionella in cooling towers than New York. Unfortunately, the New York legislation does not cover the potable water system (showers, faucets, holding tanks, etc.) in a building, or any water feature such as a lobby fountain. This is completely different from the approach taken in the UK as explained in an earlier blog, which is national in nature…
