The short answer

1 result is above the limit’s level with no violation recorded, and 1 more is above the health goal. The worst: Total trihalomethanes (TTHM), above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 1996.

Total trihalomethanes (TTHM) and haloacetic acids (HAA5): Pennsylvania’s own results, samples taken from Feb. 17, 2020 to Aug. 18, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the limit’s level, no violation

81.5ppb

Highest yearly average, 2020 to 2026

2026 average: 37.3 ppb

Averaged by year, the highest was 81.5 ppb, in 2022, above EPA’s legal limit of 80 ppb. Its highest single sample was 90.8 ppb. In 2026, the latest year on file, its six samples averaged 37.3 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for total trihalomethanes (TTHM) at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 59.6 ppb, in 2017.

Above the health goal1

Lead

Above the health goal

10ppb

90th percentile, 1996

In the latest period, 9 in 10 homes sampled were at or below 10 ppb, below 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.

16.7ppb

Highest yearly average, 2020 to 2026

2026 average: 14.1 ppb

Averaged by year, the highest was 16.7 ppb, in 2023, below EPA’s legal limit of 60 ppb. Its highest single sample was 27 ppb. In 2026, the latest year on file, its six samples averaged 14.1 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 20.4 ppb, in 2018.

What handles it

No certification claim covers this compound yet.

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: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

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.

Hardness

Moderately hard, 73 mg/L (4.2 grains per gallon), at its one sampling point, in 2025.

Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

Violations since 2016

No health-based violations on file with EPA since 2016. There are 4 monitoring or reporting violations: a sample missed, late or not reported.

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. Lca Washington Township Div’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. 17, 2020 to Aug. 18, 2026.

Testing your own tap

Lca Washington Township Div’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.
