The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Arsenic, above the legal limit. 15 health-based violations since 2016.

What handles it

What was found

Arsenic, uranium, nitrate, fluoride, chromium (total), haloacetic acids (HAA5) and total trihalomethanes (TTHM): Texas’s own results, samples taken from Feb. 10, 2020 to Aug. 19, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Arsenic

Comes from the source

Above the legal limit

10.8ppb

Highest yearly average, 2020 to 2026

2026 average: 10.0 ppb

Averaged by year, the highest was 10.8 ppb, in 2021, above EPA’s legal limit of 10 ppb. Its highest single sample was 11.2 ppb. In 2026, the latest year on file, its three samples averaged 10.0 ppb. EPA recorded violations for arsenic at this utility in 2021 and 2022. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 12.3 ppb, in 2013, and EPA recorded a violation in 2017.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Above the health goal1

Uranium

Comes from the source

Above the health goal

15.4ppb

Highest yearly average, 2020 to 2026

2026, one sample: 11.9 ppb

Averaged by year, the highest was 15.4 ppb, in 2023: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 17 ppb. In 2026, the latest year on file, its one sample was 11.9 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 15.2 ppb, in 2013.

What handles it

Below EPA’s limits2

Nitrate

Comes from the source

Below EPA’s limits

5.8ppm

Highest sample; found in 25 of 25

2026 average: 5.4 ppm

The highest sample, in 2026, was 5.8 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its three samples averaged 5.4 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 5.4 ppm, in 2013.

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

2.0ppm

Highest yearly average, 2022 to 2025

2025, one sample: 1.9 ppm

Averaged by year, the highest was 2.0 ppm, in 2022, below EPA’s legal limit of 4.0 ppm. In 2025, the latest year on file, its one sample was 1.9 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.2 ppm, in 2013.

What handles it

4 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • 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.”

  • NSF/ANSI 53

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Uranium

    For: Arsenic, Uranium

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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.

What this report can’t tell you

  • Everything else. Arsenic, uranium, nitrate, fluoride, 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. Deys Rv and Mobile Park’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. 10, 2020 to Aug. 19, 2026.

Testing your own tap

Deys Rv and Mobile Park’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.

No lab Texas certifies is within 75 miles of the area Deys Rv and Mobile Park serves on the state’s list. Some take samples by mail; the state’s page lists them all.

Texas Well Owner Network, Texas A&M AgriLife Extension: Well Informed screening events, where well owners bring in water samples to be screened for common contaminants, followed by an hour-long session explaining the results. Upcoming events are on the network's calendar. Trainings, Texas Well Owner Network.
