The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Nitrate, above the legal limit. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1995 to 2024.

Nitrate, total trihalomethanes (TTHM) and haloacetic acids (HAA5): Texas’s own results, samples taken from Feb. 26, 2020 to Sept. 9, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Nitrate

Comes from the source

Above the legal limit

13.1ppm

Highest sample; found in 27 of 27

2026 average: 5.3 ppm

In 2023, two samples were above EPA’s legal limit of 10 ppm, the highest 13.1 ppm. The next sample at the same point, within 30 days, kept the average above the limit for one; one has no follow-up sample on file within 30 days. In 2026, the latest year on file, its three samples averaged 5.3 ppm. EPA recorded a violation for nitrate at this utility in 2023.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

4.6ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 4.6 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.

Below EPA’s limits

5.8ppb

Highest yearly average, 2022 to 2025

2025, one sample: 4.5 ppb

Averaged by year, the highest was 5.8 ppb, in 2022, below EPA’s legal limit of 80 ppb. In 2025, the latest year on file, its one sample was 4.5 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 8.6 ppb, in 2016.

1.3ppb

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 1.3 ppb, in 2025, 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 1.9 ppb, in 2016.

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: Nitrate/Nitrite (30 ppm challenge), Lead Reduction

    For: Nitrate, Lead

  • NSF/ANSI 58

    Claims: Nitrate/Nitrite Reduction, Lead Reduction

    For: Nitrate, Lead

    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, total trihalomethanes (TTHM) and haloacetic acids (HAA5) results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Rra Box Community Water System’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; Texas’s results run from Feb. 26, 2020 to Sept. 9, 2026.

Testing your own tap

Rra Box Community Water System’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 Texas certifies.
