Bottled water is regulated by the Department of Consumer Protection as a food product. Many retail water bottlers publish water quality testing data, and while PFAS chemicals are not regulated in bottled water, many bottlers do test for it and include the information on their web pages. Some water bottlers use numerous sources and water quality may vary depending on the source location. If you are making your own purchasing decisions about bottled water, make sure that when you search for water quality data, you are viewing the data from the correct source.
Effective October 1, 2021; sections 86 and 87 of Public Act 21-121 require that bottlers collect samples prior to any water treatment and annually test each DPH approved bottled water source in Connecticut for unregulated contaminants such as PFAS chemicals. There are currently four Connecticut DPH-approved sources for bottled water located in the state of Connecticut, and these are the sources that bottlers would be required to sample and test. If the results of such sampling exceed Connecticut's PFAS drinking water AL, then DPH may require the bottler to discontinue use of the source until it is rendered safe to drink.
Bottled water delivered to homes in conjunction with a DEEP investigation has been tested for PFAS per the contract DEEP has with its bottled water vendor.
