The short answer

2 results are above the health goal. The worst: Nitrate, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1994 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 health goal2

Nitrate

Comes from the source

Above the health goal

11.3ppm

Highest sample; found in 55 of 55

2026 average: 5.6 ppm

One sample, in 2023, was above EPA’s legal limit of 10 ppm, at 11.3 ppm. No follow-up sample at that point within 30 days is on file. 10 ppm is also EPA’s health goal. In 2026, the latest year on file, its six samples averaged 5.6 ppm. EPA recorded no violation for nitrate at this utility since 2020.

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

Lead

Comes from pipes, often your own

Above the health goal

2.5ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 2.5 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

10.6ppb

Highest yearly average, 2020 to 2026

2026 average: 8.1 ppb

Averaged by year, the highest was 10.6 ppb, in 2020, below EPA’s legal limit of 80 ppb. Its highest single sample was 32.3 ppb. In 2026, the latest year on file, its six samples averaged 8.1 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 23.3 ppb, in 2016.

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 Lockett 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 Lockett 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.
