The short answer

2 results are above the health goal. The worst: Lead, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2004 to 2025.

Arsenic, nitrate, haloacetic acids (HAA5) and total trihalomethanes (TTHM): Tennessee’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2022, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

4.0ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 4.0 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

What handles it

Arsenic

Comes from the source

Above the health goal

0.4ppb

Highest yearly average, 2020

Averaged by year, the highest was 0.4 ppb, in 2020: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That is the only year on file.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Below EPA’s limits3

Nitrate

Comes from the source

Below EPA’s limits

0.98ppm

Highest yearly average, 2021

Averaged by year, the highest was 0.98 ppm, in 2021, below EPA’s legal limit of 10 ppm. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.97 ppm, in 2019.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

2.3ppb

Highest yearly average, 2020 to 2022

2022 average: 1.0 ppb

Averaged by year, the highest was 2.3 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2022, the latest year on file, it averaged 1.0 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.5 ppb, in 2015.

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

2.3ppb

Highest yearly average, 2020 to 2022

2022 average: 1.4 ppb

Averaged by year, the highest was 2.3 ppb, in 2020, below EPA’s legal limit of 80 ppb. In 2022, the latest year on file, it averaged 1.4 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.0 ppb, in 2018.

What handles it

  • NSF/ANSI 53 look for “Trihalomethanes (TTHM) Reduction”
  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

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, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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. Arsenic, nitrate, haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are Tennessee’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. South Carroll Utility District’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; CDC’s yearly averages for Tennessee cover 2020 to 2022.

Testing your own tap

South Carroll Utility District’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 Tennessee certifies.
