Water Quality Update: PFOA and PFOS in Drinking Water
Updated 8/13/18
- As you may be aware, Aqua, one of our region’s local water suppliers, has recently recorded two local drinking water wells as containing elevated levels of PFOA and PFOS.  The two wells are the North Hills well (in Glenside) and the Upper Dublin Township well, known as the Aidenn Lair well, which serve portions of Abington, Upper Dublin, Cheltenham and Springfield Townships. Click here for up-to-date information and resources.
