The short answer

2 results are above EPA’s legal limit. The worst: Lead, above the action level. 5 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 2016.

Total trihalomethanes (TTHM) and haloacetic acids (HAA5): Pennsylvania’s own results, samples taken from Feb. 13, 2020 to Aug. 18, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit2

Lead

Comes from pipes, often your own

Above the action level

20ppb

90th percentile, 2016

In the latest period, 9 in 10 homes sampled were at or below 20 ppb, above EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027, and this result is at or above that. EPA’s health goal for lead is zero.

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

  • NSF/ANSI 53

    Claims: Lead Reduction, Trihalomethanes (TTHM) Reduction

    For: Lead, Total trihalomethanes (TTHM)

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claims: Lead Reduction, Trihalomethanes (TTHM) Reduction

    For: Lead, Total trihalomethanes (TTHM)

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM) and haloacetic acids (HAA5) results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. East Deer Twp Water Dept’s own annual report, which it must send you every year, has the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Pennsylvania’s results run from Feb. 13, 2020 to Aug. 18, 2026.

Testing your own tap

East Deer Twp Water Dept’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Pennsylvania certifies.
