Before plastic water bottles became fashionable, we drank our water off the tap or boiled, filtered and cooled. Most municipalities supply water that is safe to drink. Water samples are tested daily and periodically for microbiological and chemical contaminants as stipulated by the Environmental Protection Agency. However the doubts relating to the safely of tap water, particularly the presence of the chlorine resistant cryptosporidium that causes intestinal disorders have not been entirely removed. Filtered tap water helps remove this harmful microbe as well as chemical contaminants such as phthalates.
The successful marketing of plastic water bottles has led to a mass belief that bottled water is cleaner and safer. While some bottle water companies source their water from fresh water springs, about 40% come from tap water that has been filtered. A report published in 1999 by the Natural Resources Defense Council based on a four year study found that 22% of bottles tested contained chemical contaminants.
Access to clean water is a basic human right, It does not make sense that we have to pay exorbitant prices to drink water from a brand-named plastic bottle that may not even be safe. These findings point to the need for a healthier way to drink and carry our water around. Carrying water in reusable plastic water bottles is another option. However, there is the risk of harmful chemicals leaching in to the water, especially when exposed to sunlight.
A healthier alternative is to carry filtered tap water in reusable containers made from eco-friendly materials. They fill the need to stay hydrated while on the go. As they can be safely re-used, there is a cost saving as well..
