Working Well

Water quality is not something that many people would consider as a potential hazard in Australian work environments, however, pipe materials, chemical treatments and potential biological contaminants can affect the health of workers.

The most common contaminant is probably copper.  Copper pipes are used to transport water within building frameworks especially in the construction of new offices or in renovations.

The problem with copper pipes is that the thin walled varieties tend to leach, particularly when new.  The rate of leaching may increase if electrical wiring is earthed along the pipes, accelerating the rate of leaching.

Recent studies have shown links between anxiety and depression - and mental disorders such as schizophrenia - and copper toxicity. 

Copper also competes with zinc for absorption and therefore can be responsible for depleted zinc levels and immune system problems.  The most common route of exposure to copper is via drinking water that has been distributed in copper water pipes.

Other problematic pipe constituents can include PVC, iron, lead and nickel. Although there are many older iron pipes in buildings, it is, in fact, the products they are soldered with (lead and nickel) that are a concern.  Chemicals such as chlorine and fluoride can be controversial additives and biological contaminants can be a problem in some water supplies.

The best solution is filtered water.  The cheapest options are under sink systems in the office or filtered water brought from home.  Stand-alone systems are fairly common in offices and bottled water can be used as a short-term solution, however, this is an expensive long-term option not only on the pocket but also on the environment.

If you are concerned about the quality of your water it can be tested by your local laboratory or consult with a Building Biologist, Occupational Hygienist or your water supplier.
