The short answer

1 result is above the health goal. The worst: Uranium, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Uranium, nitrate, fluoride, arsenic, chromium (total), haloacetic acids (HAA5) and total trihalomethanes (TTHM): Texas’s own results, samples taken from Aug. 6, 2020 to May 4, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Uranium

Comes from the source

Above the health goal

1.2ppb

Highest yearly average, 2021

Averaged by year, the highest was 1.2 ppb, in 2021: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 1.4 ppb. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.1 ppb, in 2015.

What handles it

Below EPA’s limits2

Nitrate

Comes from the source

Below EPA’s limits

1.4ppm

Highest sample; found in 13 of 13

2026 average: 1.2 ppm

The highest sample, in 2021, was 1.4 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its two samples averaged 1.2 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.8 ppm, in 2015.

What handles it

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

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.29ppm

Highest yearly average, 2021 to 2024

2024 average: 0.26 ppm

Averaged by year, the highest was 0.29 ppm, in 2021, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.33 ppm. In 2024, the latest year on file, its two samples averaged 0.26 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.32 ppm, in 2012.

What handles it

5 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic
  • Chromium (total)
  • Haloacetic acids (HAA5)
  • Lead
  • Total trihalomethanes (TTHM)

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.”

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

Filters with those claims on a certifier’s listing

None of the filters TapBuff has checked so far carry these claims. Search the certifier listings for the claim above.

What this report can’t tell you

  • Everything else. Uranium, nitrate, fluoride, arsenic, chromium (total), haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Canyon Lake Mobile Home Estates’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 Aug. 6, 2020 to May 4, 2026.

Testing your own tap

Canyon Lake Mobile Home Estates’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.
