Clean drinking water is the most basic and essential resource for human survival. Water is also the main carrier of bacteria and viruses that can lead to various horrific diseases. It also used to be free. In this age of health consciousness, drinking water has now become a very valuable and expensive commodity. Drinking water is now being filtered and purified, poured in a bottle, sealed, and sold. Anyone can assume that the water in the bottle sold in any convenience store or grocery is clean and safe since it passes through various purification processes. This is probably true. However, can you say the same for the water bottle? Water bottles come in many shapes and sizes and are made from various materials.
What are water bottles made of? There are many types of water bottles in the market today. You have the small and portable bottles with a plastic screw-on cap and you have the bigger water cooler or dispenser bottles that you typically have at home or in the office for communal use. You also have eco-friendly bottles with an integrated water filter inside to provide added purification of the water before consumption. These bottles are supposed to be reusable for as long you replace the water filter when it reaches its maximum user cycle.
These water bottles are typically made with plastic. There are two commonly used chemicals used for the creation of plastic bottles. These chemicals are the basis of the reusability of the water bottle. In fact, if you look at the bottom of each water bottle that is commercially sold, you will see a number inside a triangle indicating which type of chemical was used to create the plastic bottle.
A number 1 inside a triangle at the bottom of the plastic bottle indicates that the plastic was made with a chemical known as Polyethylene Terepthalate or PETE. This means that the plastic bottle is only good for one use. Reusing this type of plastic bottle will result in you consuming small amounts of the chemical with the drinking water, which could be harmful. According to various studies and reports, PETE is a carcinogen. There is no concrete proof on what PETE can cause to a human body when ingested in small amounts but then again do you really want to have chemicals swimming in your system?
A number 7, on the other hand, indicates that it is a Nalgene bottle. Nalgene is a type of plastic made from Polycarbonate. This type of plastic bottle enables reuse to a certain limit. Once the maximum reusability lifespan is achieved, the chemical begins to leach and will combine with the drinking water. Ingestion of this chemical is said to contribute to breast cancer emergence, fetal abnormalities, and endocrine system instability.
Some water bottle plants and manufacturers have started to coat plastic bottles with a type of resin that will lengthen the reusability of the plastic bottle. The resin will prevent the seeping of the chemicals into the water. Of course, these bottles do come at a premium due to that little extra in it to ensure your health.
Water is the lifeblood of the human body. If the water you drink consists of harmful chemicals, the natural processes in your body will start to falter which could lead dysfunction and disease. Knowing what water bottle you are using to drink water from could be that minute detail that can keep you clean, green, and healthy.
