The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Nitrate, above the legal limit. 10 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2018 to 2024.

Nitrate, uranium, fluoride, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and chromium (total): Texas’s own results, samples taken from June 11, 2020 to Aug. 12, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Nitrate

Comes from the source

Above the legal limit

11.4ppm

Highest sample; found in 26 of 26

2026 average: 6.7 ppm

In 2024, three samples were above EPA’s legal limit of 10 ppm, the highest 11.4 ppm. Three have no follow-up sample on file within 30 days. In 2026, the latest year on file, its three samples averaged 6.7 ppm. EPA recorded a violation for nitrate at this utility in 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 5.0 ppm, in 2018.

What handles it

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

Above the health goal2

Above the health goal

9.4ppb

Highest yearly average, 2022 to 2025

2025, one sample: 4.4 ppb

Averaged by year, the highest was 9.4 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. In 2025, the latest year on file, its one sample was 4.4 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 10.1 ppb, in 2019.

Above the health goal

4.6ppb

90th percentile, 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

6.2ppb

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 6.2 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 3.5 ppb, in 2016.

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, Uranium, Lead Reduction

    For: Nitrate, Uranium, 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, uranium, fluoride, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and chromium (total) results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Lake Front Buchanan’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 June 11, 2020 to Aug. 12, 2026.

Testing your own tap

Lake Front Buchanan’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.
