My wife says plastic spring bottles are safe to reuse. Are they?
My wife insists on reusing the plastic spring water bottles for drinking water. The label on the bottles clearly says in bold letters “do not reuse.” Her argument is that if the plastic is not safe to reuse, why do they put the spring water in them in the first place. I remember reading somewhere that, once used, the plastic in these bottles breaks down and gets into the refilled drinking water. I can’t convince my wife that it’s not good to reuse these bottles. Does anyone have an expert opinion on this subject?

While plastic water and soft drink bottles are sold with the intention of single use, then recycling, they can be safely reused if cleaned and handled properly. The keys are to ensure that the bottle is not damaged, has been thoroughly cleaned before each use, and is filled with clean tap water.
The reuse of bottles has recently been discussed as having possible health risks. There are two main concerns. There is a potential for the presence and growth of bacteria in these bottles, but with proper cleaning and handling, this risk can be minimised. Another health concern sometimes mentioned around the reuse of plastic bottles is that the plastic may breakdown and release ’chemicals' into the water. Current research into this topic indicates that these concerns are unfounded.
It is important to note that water or soft drink bottles shouldn't be shared during use - they should be used by one individual only to prevent the spread of germs that can lead to illnesses such as meningococcal disease.
Refilling water bottles can result in contamination of the water with bacteria, for example from the hands or mouth of the person filling or using it. With time and in warm conditions, bacteria can multiply to harmful levels, but safe handling and proper cleaning can help prevent this from happening.
Recent reports have specifically suggested that a common plasticiser, DEHA, can leach from plastic soft drink bottles into the liquids they hold, particularly with reuse. However, the majority of plastic water and soft drink bottles are made with a substance called PET, and do not contain DEHA.
While current research indicates chemicals are not released into water by reuse, many of these bottles are manufactured to be recycled, not reused. Some plastic bottles can warp when exposed to heat in the cleaning process. It is therefore important to ensure that after the bottle has been washed in hot water and left to air dry that it is intact and has not been damaged.
Before filling bottles, wash and dry your hands thoroughly so that you don't contaminated it with bacteria.
Examine the bottle to ensure that it is not damaged.
After use, clean bottles and nozzles with hot, soapy water and make sure the inside of the bottle air dries completely before use.
Use good quality water from a safe source.
Bottles should be used by one individual only. Don't share bottles- saliva can transfer germs that can lead to illnesses such as meningococcal disease. Make sure they are labelled with the person's name for easy identification
