Dear Aqua Pennsylvania Customer:
At Aqua, our mission has always been to protect and provide Earth’s most essential resource. When something interferes with that mission, we take it very seriously and we want to assure our customers that we are taking appropriate measures to ensure the safety and quality of their drinking water each and every day.
In recent years, the presence of two contaminants – Perfluorooctanoic acid (PFOA) and Perfluorooctanesulfonic acid (PFOS), known as a part of the PFAS family of chemicals – in drinking water supplies has become a concern across the country and around the world.
In May 2016, the U.S. Environmental Protection Agency replaced its 2009 provisional health advisories for PFAS with new, lifetime health advisories, setting a health advisory level of 70-parts per trillion for both contaminants. This lower limit is of particular interest in those areas of eastern Montgomery County and Bucks County, where groundwater contamination from PFAS is believed to originate from nearby military bases.
Since the health advisory limit was announced in 2016, Aqua has taken proactive measures to ensure that water provided outperforms the EPA’s 70 PPT health advisory, including investing heavily in equipment for regular in-house analysis; installing granular activated carbon (GAC) filters on two systems with the highest level of PFAS; conducting engineering evaluations of the Neshaminy water treatment plant and evaluating impacts of the Air National Guard’s treatment system on levels in the creek; and continually assessing alternative treatment options, including ion exchange resins and other technologies.
Aqua continues to develop and expand a PFAS action plan that employs a tiered approach, starting with systems of highest PFAS concentrations and evaluating best actions for each. Developing this plan for all sources is ongoing and may take some time due in part to the regional and interconnected nature of our systems, which require coordination with various local, state and federal stakeholders.
We look forward to updating our partners and customers on the status of our plan and resulting activity, and we will continue to update this website with information on our progress. If you have additional questions that are not answered here, please contact us at 877.987.2782 or custservreply@AquaAmerica.com, or visit our Resources page to access additional information.
