Health Risks of Public Pools 

Swimming is a good exercise and being in a pool is a cooling and refreshing experience. The water is inviting but, in spite of being disinfected, the water could still be harboring pathogens and other substances harmful to people’s health when people come in contact with them through their skin, by swallowing water or inhaling water vapor. 

What are the health risks of swimming in public pools? 

1. Infectious diseases. 

Because public pools are used by many people, a number of which have unhygienic behaviors, public pools are notorious in harboring pathogens.  These behaviors include urinating, defecating, spitting, and not showering before swimming, by which pathogens from infected individuals come in contact with the water. Pathogens could also come from bird droppings, dead animals, decaying leaves, or contaminated rainwater.

  • Bacterial – Legionnaires’ Disease is a dangerous, potentially fatal lung disease transmitted by the bacterium Legionella. Its symptoms are similar to those of pneumonia. It is transmitted when water is swallowed or water vapor is inhaled. 

Swimmer’s ear is a bacterial infection of the ear canal when water enters it and is left to stay for a long time. The bacteria thrive in the water when the pool is treated with imbalanced levels of disinfectant and pH levels. 

Gastrointestinal diseases, like salmonellosis (caused by the bacterium Salmonella), bacillary dysentery (caused by the bacterium Shigella), and food poisoning and diarrhea (caused by certain forms of Escherichia coli) could be contracted when water contaminated with feces is swallowed.  

Urinary tract infection (UTI) could be acquired through contact with Pseudomonas aeruginosa in the water from a person having the disease. 

  • Fungal – Athlete’s Foot is transmitted through the skin coming in contact with pieces of skin from an infected person in the water, common showers, and changing rooms.  
  • Viral – Adenoviruses could cause gastroenteritis, respiratory infections, eye infections, and other diseases while rotaviruses could cause severe gastroenteritis and dehydration in young children. 

Influenza could be contacted from carriers of the virus, through inhalation or physical contact. 

  • Parasitic protozoan – The diarrheal diseases giardiasis and cryptosporidiosis caused, respectively, by Giardia and Cryptosporidium are passed on from feces in the water.


2. Disinfectant by-products (DBPs).

Recent studies show that sweat, urine, saliva, hair, skin particles, feces, cosmetics and sunscreens, when mixed with chlorinated water, form disinfectant by-products (DBPs). These DBPs trigger genes to mutate, damaging the DNA and increasing cancer risk. DBPs can be absorbed through the skin, swallowed or inhaled.


3. Chlorine itself.

Studies show that too much chlorine, evidenced by its strong smell, causes lung irritation and increases the risk of developing asthma. 

Health risks of public pools could be minimized by: 

  • informing/teaching people hygienic behaviors when using public pools 
  • disinfecting pool water with chlorine in the right amount or with ozone and ultraviolet radiation, to kill parasitic protozoans 
  • fitting the pool with the correct filter, such as the pool filters by Davey or Onga, for trapping impurities and other debris that may harbor pathogens 
  • maintaining and repairing pools using quality supplies and equipment, such as be had from APS Rewinds and Sales.   

Make Your Events Something to Remember

You work in event organizing and you have been assigned to plan the layout of the event area. The area is an open field and the event, this time, is a home-made food and handicrafts fair. Your booths have sold out and the sellers are expecting a big attendance since the event has been well-announced. If this event is successful, it will be repeated next year. That would be a good mark regarding your job performance!

Vinyl Wrapping – An Alternative to Paint 

There’s an alternative to painting a boat and it’s called vinyl wrapping. A self-adhesive film of vinyl is applied over the body or hull of a boat to protect it and its underlying substrate from the elements. A quality bo at vinyl wrap also gives some sort of cosmetic “makeover” to the boat to restore or to give it a new look. This kind of film is available in many colors, designs and finishes, so a boat can be easily customized according to an owner’s taste. It could even make a boat a vehicle for advertising.  Continue reading Vinyl Wrapping – An Alternative to Paint 

Does Your House Have Pests?

How do you know if your house is pest-infested or if the sounds you hear at night right above your bed is not actually a ghost?

It might be funny to think there is a ghost in your house, but having a pest infested home is no joke. They don’t just ruin your furniture, lawn and walls, but they can be hazardous to your health as they carry dangerous diseases. Rat urine can give you leptospirosis and cockroaches carry salmonella Typhi which causes Typhoid.

Your home should be a place where you feel safe, not a place where you have to feel scared to live in because you are sharing a roof with unwanted creatures.

Older homes are more prone to pest infestation than newer ones.

These are a few things you can ask yourself and what to look for if you are suspicious that there are pests in your home:

  • Does your home smell “funny”?
  • Do your walls have spots?
  • Do your furniture have new gnaw marks on them?
  • Are there track marks on your floor? (such as rat paw prints)
  • Do you hear scratches or tiny quick footsteps around the house?
  • Are there small animal droppings around your home?
  • Are there dead or live bugs around your house? Notice if the bugs are of the same species, your home is probably their home too.
  • Do the walls have holes? Does the floor seem saggy? This may be a sign of a termite infestation.
  • Do you always get itchy bites?

These are a few things worth considering for outdoors:

  • Note if the immediate premise is clean or if there is unattended garbage nearby.
  • If the building is near a body of water like a fountain, a lake or a pond,  this might be a breeding ground for mosquitoes. Stagnant water like dripping pipes, gutters and an unattended swimming pool can also cause a mosquito problem.
  • Be aware of visible insect or any other animal tracks around the premises. Notice if leaves and grasses have any evidence of bites on the edges.
  • Check the walls and pavements for any cracks.
  • Look if there is an anthill around the premises. If you see an ant trail, follow it as it will lead you to it.

It is also good to look for these tattle tale signs when you are looking for a room or house to rent/buy. You can ask the landlord what their pest control policy is. See if they regularly check for pests and provide pest control treatments or not.

Contacting an expert pest control is your best bet. They have the expertise to check if your house is indeed a pest haven or not, and they know the best way to get rid of them while keeping you safe from dangerous pest-killing chemicals.

Aside from the pesky and gross cockroaches, rats are also very common pests almost anywhere in the world. Luckily, there should be a number of companies that offer pest management and reliable rodent control. They do not just diagnose the situation, but they will also recommend the best way to prevent any pests from returning.

For those that do not have a pest problem at home, hiring an expert pest control is recommended to prevent pest infestation before it starts. It is better to be safe than sorry.
