Of course, the type of water treatment necessary depends on the contaminants in the untreated water. For example, if the water has microbiological contamination, boiling filtered water for three minutes is a simple way to kill biological contaminants. Simple systems such as Brita filters can remove most heavy metals such as lead. Bottled water may be another option, assuming that its quality is reliable. Your health unit is likely to have information on the local water quality, as well as practical solutions to make it safe to drink.

I can't stand roaches, but I'm more concerned about my children being exposed to so much pesticide. Automatically spraying pesticides at frequent intervals is inadvisable and inconsistent with the Department's integrated pest management policy. Bring this concern to the attention of your post occupational safety and health officer, who is often the general services officer or facilities manager. Other members of post's safety, health and environmental management committee such as the post nurse or physician would also be interested in this issue. Pesticides should be used only as needed after pest prevalence reduction measures and self-help measures have proven ineffective.
