For several years the compound known as Bisphenol A has repeatedly made headlines as a threat to humans. Studies have linked it to a wide range of ailments and medical conditions, none of which the average person would want.
BPA, a toxic component used in plastic manufacture that hardens the material, has long been connected to a wide variety of adverse effects, including increased risks of brain, reproductive, cardiac, and immune system diseases and disorders; problems with liver function testing; interruptions in chemotherapy treatment; and links with serious health problems. Studies have overwhelmingly found BPA to have negative effects at doses lower than the U.S. Food and Drug Administration’s (FDA) current standards; retention in the body longer than was previously believed; leeching into liquids being held in containers regardless of the containers’ temperature; and longer lasting damage, which can be passed to future generations. Over 200 peer-reviewed studies have linked BPA to health problems. ( source )
So… Naturally people want to know what sorts of containers they ought to avoid so they can minimize their exposure.
Look for the number 7 on plastic products.
A commonly used plastic hardener and polycarbonate plastic byproduct, BPA has been found in everything from baby bottles, sippy cup, water bottles, aluminum can linings, eyeglasses, and cars, to DVD and CD cases and some dental sealants. BPA can also be found in appliances and windshields; on recyclable bottles, BPA as a component can be verified if the item contains recycling number 7. ( source )
What does BPA have to do with water testing? Not much… except that it really doesn’t make a whole lot of sense to put freshly filtered, pure drinking water into a container that has the potential to leach toxic chemicals into it.
As usual we suggest people test the quality of their water routinely… and now we suggest they be careful not to use portable water containers made with BPA.
