Is it safe to refill single-use water bottles?

Most drinking water bottles are PET bottles (Number 1). The bottles are safe to reuse as long as they're cleaned with hot, soapy water and thoroughly dried every time you refill them, to quell potential bacteria growth. Extensive testing has demonstrated that PET, used widely in food and drink containers, is safe for both single and repeated use.

For safety: Clean your bottles regularly with hot, soapy water.

Leaching of Plasticizers: This is an urban myth. See the related links.

The bottom line: Go ahead and reuse those water bottles. Just keep them clean.

Actually, the leaching of PET Plasticizers is Not just a myth. The exposure of these plastics to hot water and soap can even SPEED UP the release of toxins from the plastic into the water! Just use a cup or buy a new water bottle (atleast) weekly. Also, specifically created re-usable water bottles are available at most stores for about the same price as plastic bottles and can last years--it is important to note, however, that these do still require frequent cleaning.

It is better to use the 5 gallon PC or PET usable containers and refill at Vending machines or Water stores.

The quality of the water stores are the best, excellent RO water with a TDS of below 40.

No because you cant really clean a plastic bottle because of the small ring around it so the germs start eating the plastic and you will get sick.You will realise this when the drink tastes FUNKY.

There are two main categories of concern with regard to water bottle reuse:

The case against reusing plastic bottles makes many claims, but cites no evidence. In contrast, the case for safe bottle reuse has a wealth of peer-reviewed scientific evidence supporting it. A prime reference can be found in the following document from the International Life Sciences Institute:

Note especially the following paragraph:

"There has been increasing public concern that certain man-made chemicals, if absorbed into the body, can act like the female hormone oestrogen disrupting the normal endocrine cycles and causing genetic disorders or adverse reproduction effects like reduced male sperm counts. It is important to stress that the chemistry of compounds that are used to manufacture PET shows no evidence of oestrogenic activity. There is a significant body of evidence that demonstrates that the use of PET is not a concern and is perfectly safe in this respect. PET and its components have no links with any reported endocrine disrupters [9,15,16]."

It is understandable that people would be scared about the transfer of plastic packaging materials to their food, but there is very little evidence to support this fear, and a large body of evidence to refute it.
