Update on PFAS in Newtown's Water Supply

Update on PFAS in Newtown's Water Supply

As late as August 2018, Dan Angove, General Manager of the Artesian Water Company (NAWC), reported that PFAS - perfluorinated compounds Definition - in the town's drinking water were at "undetectable" levels (see below).

After NAWC sent a letter to residents in February 2019, that PFAS were detected in Newtown's water, Supervisor Mack requested that Mr. Angove return to report on the situation. Mr. Angove complied and presented the latest Q1 2019 test results at the May 8, 2019, Board of Supervisors public meeting.

At the meeting, Supervisor Mack asked Mr. Angove to explain the results in comparison to the Q4 results focusing on (1) how sampling is done, (2) when was sampling done, (3) were multiple samples collected & combined for the test? (4) what company did the testing, (5) how accurate is the test? What's the margin of error? Residents also asked if the NAWC had set aside money to lower the levels of PFAS if necessary to comply with the Maximum Contamination Levels (MCLs) set by the PA Department of Environmental Protection.

Regarding the letter that NAWC sent to Newtown Township residents:

Dan Angove, Assistant General Manager, Newtown Artesian Water Company, gave a report on Newtown's drinking water at the August 8, 2018, Board of Supervisors meeting. Mr. Angove answered questions from Supervisor John Mack about Maximum Compliance Levels of PFAS - perfluorinated compounds - in the town's drinking water and assured the Township that PFAS were at "undetectable" levels (below 5 ppt) in the Township's water supply.

As shown in the chart below, there are several conflicting standards for what is considered the Maximum Contaminant Level (MCL) for these compounds in drinking water and communities are demanding that contaminated wells be shut down even if the water is well below the MCL suggested by the EPA (see Upper Dublin video below the chart).
