The short answer

1 result is above EPA’s legal limit. The worst: Lead, above the action level. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2014 to 2026.

Total trihalomethanes (TTHM) and haloacetic acids (HAA5): Kansas’s own results, samples taken from Jan. 26, 2020 to July 21, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Lead

Comes from pipes, often your own

Above the action level

46.5ppb

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.”

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 Kansas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Montgomery Co RWD 2c B’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; Kansas’s results run from Jan. 26, 2020 to July 21, 2026.

Testing your own tap

Montgomery Co RWD 2c B’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 Kansas certifies.

No lab Kansas certifies is within 75 miles of the area Montgomery Co RWD 2c B serves on the state’s list. Some take samples by mail; the state’s page lists them all.
