The store doesn't know what a buyer does with their product, leaving milk in the hot sun in a car or a kid dumps some fish tank water back in the spring water. All ingested products have batch numbers on the packaging so that the gov't can determine what happened at a factory, by batch. Individual problems are just that, and the store is just obliging customers who are unhappy.
This is not to suggest that you leave milk out or put something in the water! Just that if you want to know what happened, you are on your own getting testing done.
I personally would never buy bottled water, having read some stories that suggest it isn't just a waste of money, but also there are many brands that are dubious at best in terms of 'spring' quality. There might be one or two that are very well known as being 100% from real springs that are 100% uncontaminated.
