Drinking enough water is essential to replace the large amounts of water lost each day from our body. But drinking water, including bottled water may reasonably contain at least small amounts of some unknown contaminants, especially endocrin disrupting compounds (EDs). This statement is proven when EDCs were observed across the drinking water supply of 28 million Americans even though United States is known for having very high quality of tap water with an incredible water treatment, storage and distribution.
Consumers should be aware that EDCs can be found in everyday products such as detergents, toothpaste, cosmetics, food and beverage cans, kitchenware and plastic toys. Furthermore, may water treatment facilities particularly the conventional one has relatively low capability in removing these chemicals. The existence of EDCs can have serious adverse health impacts in low doses. The health problems including the commonly known diseases such as cancer, diabetes and obesity.
Also, a study reported infants and children, which entails greater drinking water consumption on a body0weight basis, could have approximately 6 times greater exposure and risk than those in adolescence and adulthood. Currently, the inadvertent exposure to EDCs via drinking water consumption and the associated risks may have been underestimated and subsequently not investigated because of the incompetent water monitoring and management.
The World Health Organization (WHO) has also declared that the development of formal guideline values for EDCs in the WHO Guidelines for Drinking Water Quality is unwarranted. Should you still have concerns about sustainable access to safe drinking water, it is important to know the current environmental regulations and policy are under the threat of EDCs.
