Do you know if your water bottle is safe? We all want safe water to drink. However, even if we buy clean bottled water or put our own clean water in an existing bottle, the water could be unsafe if the bottle is unsafe. Know what to look for in bottled water and how to use existing bottles to be safe.
Read the number on the bottom of the bottle.
Each water bottle has a number on the bottom of it. That number tells what kind of plastic it is. Even though all plastic bottles used to package water have been approved by the FDA, they may not actually be as safe we might like to think. Certain kinds of plastic can leach chemicals that have been linked to risks with brain development in fetuses, infants and children. Never drink water from a bottle with #3,6, or 7 on it.
Know the risks of the "bad" plastics.
Plastics with the #3 on them are also used in food containers and have been linked to certain cancers (breast and prostrate), hormonal imbalances and other diseases. Plastics with the #6 on them have been shown to interfere with hormones. Plastics with the # 7 on them are used for baby bottles and 5 Gallon water bottles. That plastic can leach a toxin that has been linked to breast and ovarian cancer. The U.S. Center for Disease Control and Prevention found that toxic chemical in over 90% of the people it tested. Stay away from #3,6, and 7. Number 7 has been shown to be the greatest concern, while #3 and 6 have been linked to adverse effects. You can find the study by the Health Department in the "Additional Resources" section.
Use, but do not reuse plastic bottles with the numbers 1,2,4 and 5.
So far, those numbers are being reported as safe. However, they might not even be safe when reused. We all want to reuse and save on repurchasing when we can. However, plastic bottles tend to bend and get small, even unnoticeable, cracks in them as they are used. And plastic bottles are being made thinner than ever. Do you notice how the new bottles even tend to suck in more as you drink the water from them? The cracks in used bottles can cause them to leach out toxins. Reports say that you can wash and reuse them once or twice, but, personally, I would not trust that.
Do not heat bottles or any other plastic container.
Even the good plastics can leach chemicals when heated. Never put warm or hot liquid into any water bottle or plastic container. Also, avoid heating things in plastic containers.
