Is Hard Water Making You Ill?

We've always considered hard water to be an aesthetic concern. You know: hard to clean bathtub ring and film on shower tiles, dry itchy skin after bathing, dramatically higher cleaning costs, increased heating and maintenance costs due to scale build up.

But now, evidence is making us reconsider what that scale can actually do. 

Legionnaires Disease is far more common that we think.

The CDC estimates that between 8,000 and 18,000 cases are hospitalized with many cases going unreported. CDC Fact Sheet.

Any place moisture can build up may cause bacteria, such as legionella, to grow. The bacteria can grow in hot tubs, air conditioning systems (especially large commercial units), hot water tanks, plumbing systems and cooling towers. Limescale deposits in the water system allow water to pool when the fixtures aren’t in use. This pooling allows bacteria to grow and potentially infect those using or exposed to the system.

“By far the greatest risk lies within the humble hot and cold water systems, which deliver the disease through taps and shower heads. Legionella bacteria thrive in temperatures between 20-45 degrees Celsius; and if water is allowed to sit at these temperatures the bacterium can multiply into large numbers which can cause Legionnaires’ disease,” according to Simon French, a legionella expert and HVCA Service and Facilities Group member.

In another study, scientists tested shower heads. Tests revealed nearly a third of devices harbour significant levels of a bug that causes lung disease.
Levels of Mycobacterium avium were 100 times higher than those found in typical household water supplies. 

M. avium forms a biofilm that clings to the inside of the shower head, reports the National Academy of Science.

Lead researcher Professor Norman Pace, said: "If you are getting a face full of water when you first turn your shower on, that means you are probably getting a particularly high load of Mycobacterium avium, which may not be too healthy."  BBC Article

Clean your water cooler!

If you have a water cooler, it is important to clean it regularly. How often it should be done varies with recommendations from yearly, to every 6 months to Health Canada' recommendation of every time you change the bottle. Health Canada Bottled Water Page

How do you clean your cooler? These are the steps that we use:


1)     Unplug cord and allow the unit to come to room temperature. For Hot and Cold coolers, run some water out of the hot tap after unplugging to cool the water.
2)   Remove the bottle.  Empty the reservoir through the faucets. For Hot and Cold coolers, also remove the drain plug at the back of the cooler.  Replace after the hot tank is empty.
3)      Remove the lid of your dispenser.  No-Spill tops require a little extra effort to pull off and push on. Some have a locking pin. Some require a partial counter-clockwise turn before removing.
4)      Mix a cleaning solution by adding 1 tablespoon of household bleach to 1 gallon of fresh water. Thoroughly wipe inside of reservoir with cleaning solution and a clean cloth or paper towel.
5)      Fill reservoir with cleaning solution. For Hot and Cold coolers, open the hot faucet until water comes out and top up the reservoir with solution.
6)      Spray a diluted solution of bleach and water inside the faucet spouts.  Let stand for 5 minutes, and then drain through the faucets. For Hot and Cold coolers, also remove the drain plug at the back of the cooler.  Replace after the hot tank is empty.
7)      Fill the reservoir with fresh water. For Hot and Cold coolers, open the hot faucet until water comes out and top up the reservoir with fresh water.
8)      Drain through the faucets. For Hot and Cold coolers, also remove the drain plug at the back of the cooler.  Replace after the hot tank is empty.
9)      Repeat steps 7 & 8 once more.
10)  Remove the air filter from the top.
11)  Clean the top in a clean sink filled with fresh water and a mild bleach solution.
12)  Rinse the top with fresh water, and dry with clean paper towel.
13)  Replace air filter
14)  Replace cooler top.
15)  Replace bottle.
16)  Open faucets one at a time until water runs from each.
17)  Plug unit back in.
18) Water should be chilled and hot, if so equipped in about 1/2 hour.
