Hotel Spa Pool Safety Tips: Water Clarity And Cleaning Is Vital To Minimizing Health Risks

“…Many of the outbreaks related to swimming pools would have been prevented or reduced if the pool had been well managed….”

“….these challenges can be met through a combination of the following factors:

  • treatment (to remove particulates, pollutants and microorganisms), including filtration and disinfection (to remove/inactivate infectious microorganisms);
  • pool hydraulics (to ensure effective distribution of disinfectant throughout the pool, good mixing and removal of contaminated water);
  • addition of fresh water at frequent intervals (to dilute substances that cannot be removed from the water by treatment);
  • cleaning (to remove biofilms from surfaces, sediments from the pool floor and particulates adsorbed to filter materials);
  • and ventilation of indoor pools (to remove volatile disinfection by-products and radon).

(From a FreeDrinkingWater.com article)  Controlling clarity, the most important water quality criterion, involves adequate water treatment, including filtration. The control of pathogens is typically achieved by a combination of circulation of pool water through treatment (normally requiring some form of filtration plus disinfection) and the application of a chemical residual disinfectant to inactivate microorganisms introduced to the pool itself by, for instance, bathers. As not all infectious agents are killed by the most frequently used residual disinfectants, and as circulation through the physical treatment processes is slow, it is necessary to minimize accidental faecal releases and vomit (and to respond effectively to them when they occur) and to minimize the introduction of bather-shed organisms by pre-swim hygiene.

Hotel Swimming Pool Water Health Risks: Maintaining Pool Equipment And Water Quality, Including Cleaning Pool Decks Daily, Can Help Reduce Health Hazards

Swimming pool water care involves you cleaning your pool deck and walkways at least once a day. This will help in keeping contaminants from entering into your pool or spa water. Additionally, maintaining good water quality and eliminating non-enteric waterborne illnesses, require daily swimming pool cleaning.

(From a Swimming-Pool-Care.com article)   Some waterborne illnesses are caused by non-enteric pathogens. These pathogens can be found in poorly maintained swimming pools and spas. Because of these potential health hazards, your swimming pool equipment and your water quality, should be checked constantly. This is a daily requirement.Non-enteric pathogens that are usually found in poorly maintained swimming pools include:

  • Pseudomonas aeruginosa. This is an opportunistic pathogen that causes infection of the respiratory system. It can also cause dermatitis and infections of the soft tissues in the body.Pseudomonas pathogens are usually found in a biofilm environment. Biofilm is normally found in the circulation system of your swimming pools and spas. This pathogen can tolerate a variety of physical conditions and it is highly resistant to antibiotics. 

Symptoms that are associated with pseudomonas aeruginosa!

Symptoms for this particular form of waterborne illnesses that are found in pools, are as follows:

  • Itchy skin. 
  • Bumpy rashes that are tender to the touch and appear reddish in color. 
  • Puss filled blisters that usually form around your hair follicles. The reason for this, is due to the fact that infection of pseudomonas usually forms in the hair follicles.

Other non-enteric pathogens that are found in pools and spas!

When the circulation system for your swimming pools and spas are poorly maintained, non-enteric pathogens are developed. These include:

  • Mycobacterium spp. 
  • Staphylococius aureus. 
  • Leptospira interrogans. 
  • Trichophyton spp. 
  • Epidmerophyton floccosum. this pathogen usually is the cause for dermic or respiratory infections. 
  • Acanthamoeba spp. 
  • Human papilloma virus. 
  • Legionella pneumophila. This particular type of waterborne illness, is commonly referred to as legionellosis or legionnaires disease. This is a severe case of pneumonia. Sadly this bacteria exist in poorly maintained spas and is transmitted through the mist that is common with this type of environment.Legionella pneumophila cause two different types of diseases. The first is called legionnaires disease, as was mentioned earlier. This my friend is the more severe form of the waterborne illnesses. The next stage of this infection, is called pontiac fever. Fortunately for us, this is the more milder side of the disease.Proper disinfectant levels in your spa, along with frequent maintenance of your filter, are critical steps necessary to control these bacteria. 
  • Molluscipox virus. This is a virus that causes molluscum contogiosum. Molluscum contogiosum is a common skin infection that is not serious. It will clear up on its own, without any form of treatment. Nevertheless the condition could take up to several months before it clears but there are no long term effects it. 
  • Verrucas. This infection, is commonly known as plantar warts. Waterborne illnesses of this type are usually acquired through direct contact with pool decks and locker room floors which have been contaminated. Contamination of these surfaces, are usually caused by skin fragments that are the cause of the infections.The skin fragments which are shed by other users, are normally infected with causative papliomavirus. Ordinarily, preventing plantar warts is achieved through regular cleaning and maintenance of your swimming pool decks and locker room floors. 
  • Athlete’s foot. This is a ringworm infection that is caused by dermatophyte fungi. A very itchy scale between the toes is indication of this infection. Athlete’s foot is contracted in the same manner as plantar warts.Infections is again from infected skin fragments that have the dermatophyte fungi. Individuals with severe cases of this condition, should not be allowed to use your recreational water facility. This will eliminate infection of other users.

Spa Pool Risks: Hopsitality Owners Should Be Aware Of Microorganisms Present In Spa Pools And Take Steps To Prevent Proliferation

 The risk potential of contact with pathogens through spa pool use has been exacerbated through the promotion of the therapeutic properties of spas. Spa treatments can provide suffers of muscular skeletal disorders, such as rheumatism, relief from pain. However, this has become confused with mineral spa treatments for general ailments. Consequently, many people suffering from common illnesses, such as influenza or digestion complaints, frequent leisure spa pools hoping to gain some relief from their symptoms. Unfortunately, such practice can introduce the bacteria into the Spa system and consequently increase the risk of infection for other bathers.

(From a NalcoEurope.com posting)   Spa pools are the third most common cause of legionnaires disease and are known to harbour other bacteria that can cause serious skin complaints and even blindness.

A commercial spa pool should be considered as any bath that consists of a self-contained body of water, which is recirculated, filtered, heated, and chemically treated but is not emptied and cleaned and refilled after each bather.

Due to the high water temperatures (30-40°C), availability of nutrients and convoluted design Spa pools are particularly prone to microorganism proliferation. Furthermore, due to the high level of contact between the bather’s skin and the spa surface, biofilms quickly form and so frequent cleaning is essential.

Continuous filtration to remove contaminants and the application of a disinfectant is imperative in order to ensure safe hygienic conditions.

Spa pools should not be considered as small swimming pools. Spa pools operate with much smaller volumes of water in relation to the number of bathers that use them. In addition, water temperatures are much higher as is aerosol generation and the general risk to bathers from the number of water borne pathogens.

The following table identifies the micro flora that are of particular concern in spas:

Bacteria Illness Description Other Detail
Shigella Diarrhoea, Fever, Nausea 1-3 day incubation, 4-7 day illness,
E Coli Diarrhoea, Vomiting, Fever 3-4 day incubation, & day illness
Giardia Gastroenteritis 7-12 day incubation, 7-10 day illness,
Cryptosporidium Diarrhoea, Vomiting, Fever, Cramps 7 day incubation, 10-14 day illness,
Legionella Flu Like Pneumonia Aerosols – SPA & HVAC
Pseudomonas Aeruginosa Follicultis – Swelling of Ear Canal Transmitted on Any Wet Surface
Mycobacterium spp Broken Skin Infections Bather Shed on Wet Surfaces
Mycobacterium. Avium Respiratory Illness – Flu Hypersensitivity pneumonitis Bather Shed.
Aerosol Transmission
Staphylococcus Aureus Skin, Wound, Eye & Ear Infections. Impetigo Bather Shed.
Leptospira Interrogans Weils Disease – Haemorrhagic Jaundice
Aseptic Meningitis
10-20 day incubation, Pool Infected by Urine from Infected Humans and Animals
