The short answer

2 results are above EPA’s legal limit. The worst: Lead, above the action level. 3 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2024 to 2025.

Nitrate, haloacetic acids (HAA5), total trihalomethanes (TTHM), arsenic and uranium: North Carolina’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 April 2, 2014 to April 5, 2017. Newer results are in the utility’s annual water quality report.

Above the legal limit2

Lead

Comes from pipes, often your own

Above the action level

18ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 18 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

Nitrate

Comes from the source

Above the legal limit

6.0ppm

Highest yearly average, 2020 to 2023

2023 average: 5.7 ppm

Averaged by year, the highest was 6.0 ppm, in 2020, below EPA’s legal limit of 10 ppm. In 2023, the latest year on file, it averaged 5.7 ppm. EPA judges this limit at each sampling point, and recorded violations for nitrate at this utility in 2022 and 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 10.6 ppm, in 2018, and EPA recorded a violation in 2018.

What handles it

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

Below EPA’s limits2

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

5.5ppb

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 5.5 ppb, in 2023, below EPA’s legal limit of 60 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.8 ppb, in 2014.

Total trihalomethanes (TTHM)

Below EPA’s limits

5.3ppb

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 5.3 ppb, in 2023, below EPA’s legal limit of 80 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 9.2 ppb, in 2017.

What handles it

  • NSF/ANSI 53 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, Nitrate/Nitrite (30 ppm challenge)

    For: Lead, Nitrate

  • NSF/ANSI 58

    Claims: Lead Reduction, Nitrate/Nitrite Reduction

    For: Lead, Nitrate

    Other certifiers’ wording: Nitrate

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. Nitrate, haloacetic acids (HAA5), total trihalomethanes (TTHM), arsenic and uranium results here are North Carolina’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. Winstead Mobile Terrace’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 North Carolina cover 2020 to 2023; EPA’s compliance samples are from April 2, 2014 to April 5, 2017.

Testing your own tap

Winstead Mobile Terrace’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 North Carolina certifies.
