The short answer

2 results are above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 15 health-based violations since 2016.

What handles it

What was found

Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and nitrate: Missouri’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from Sept. 27, 2012 to Sept. 19, 2018. Newer results are in the utility’s annual water quality report.

Above the legal limit2

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the legal limit

88.4ppb

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 88.4 ppb, in 2023, above EPA’s legal limit of 80 ppb. That was also the latest year on file. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2023, 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 73.2 ppb, in 2018.

Haloacetic acids (HAA5)

Forms or is added in treatment

Above the legal limit

60.1ppb

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 60.1 ppb, in 2023, which EPA rounds to 60 ppb to compare: at its legal limit of 60 ppb, not above it. That was also the latest year on file. EPA judges this limit at each sampling point, and recorded violations for haloacetic acids (HAA5) at this utility in 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 39.3 ppb, in 2018.

2018: not found

Averaged by year, the highest was 2.0 ppb, in 2012, below EPA’s legal limit of 100 ppb. In 2018, the latest year on file, it wasn’t found in its one sample.

  • Nitrate

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

    Claim: Trihalomethanes (TTHM) Reduction

    For: Total trihalomethanes (TTHM)

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claim: Trihalomethanes (TTHM) Reduction

    For: Total trihalomethanes (TTHM)

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and nitrate results here are Missouri’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. Blodgett PWS’s own annual report, which it must send you every year, has newer results for those and 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; CDC’s yearly averages for Missouri cover 2020 to 2023; EPA’s compliance samples are from Sept. 27, 2012 to Sept. 19, 2018.

Testing your own tap

Blodgett PWS’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 Missouri certifies.
