So when I was confronted with the question out of the blue, is tap water really dangerous? I had to say a quick no, not it is not and had to query her why she had asked something like that.
It seems that some news story on the TV had spoken about how our drinking water was under threat from an ever growing number of man made chemicals, used in the making of many everyday items that we use.
Kids at that age seem to have an enquiring mind and not wishing to sound unhelpful I said that we should do some combined, further research on the subject.
By delving deeper into any subject you do come up with some fascinating facts like when several hundred years ago they brewed and drank beer rather than water, because they knew it was unsafe to drink in its natural form.
But the relevance for me was, is tap water really dangerous today.
I was none to pleased to discover that although our municipal water suppliers do a reasonable job of treating the water so it's safe for us to drink and use when it gets to our homes, it might still contain contaminants.
Seems that not all treatment techniques and methods are successful at removing everything that should not be there.
Sure, we can remove any unwanted solids reasonably well but the soluble properties that water has means it could contain substances we would be wise to avoid given the choice.
That's what it's all about at the end of the day, making the right choices that impact not only on ourselves but our immediate family.
Each of us has the ability to take steps even small ones.
For me, just having slight doubts about my tap water meant installing a home water solution which should pay for itself over a short period of time and best of all, give me some peace of mind.
