The manufacturing of water sold in supermarkets is highly regulated and the water undergoes extensive testing.  The likelihood that you will encounter a contaminated container of distilled water on the supermarket shelves is extremely low.

A common perception. But not in our experience. We test this water in our microbial lab, and occasionally we detect contaminated batches. Returned two bottles just the other week.

Some years ago I was asked to do a consultancy for one of the largest bottled water suppliers in Australia. My initial evaluation revealed inadequately qualified and trained  QC and laboratory staff, and vastly inadequate lab equipment and water testing protocols. This experience shattered my assumptions about the bottled water industry.

I have a small home-based lab. Can you recommend an affordable testing kit for water? Thanks in advance.
