Ever wonder why coffee maker instructions warn you to run a batch of hot water through your new coffee maker before brewing your first pot of coffee?
Consumer Reports did a study on water run through the home coffee brewers according to the manufacturers’ instructions and had an outside lab analyze the water for semivolatile compounds, including six common plasticizers (phthalates) used in consumer products.
Studies were done for bisphenol A (BPA), benzyl butyl phthalate (BBP) and benzyl alcohol. Seven coffee makers were studied, and two of them stored water in them until ready for brewing. Small levels of benzyl butyl phthalate (BBP) and benzyl alcohol were found in water heated in six of the seven coffeemakers models. They also found very low levels of BPA in two of those six coffeemakers.
The good news: Based on their analysis, they concluded the levels of compounds detected would not be expected to pose a health risk.
