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. 2 health-based violations since 2016.

What handles it

What was found

Nitrate, arsenic, uranium, fluoride and chromium (total): Texas’s own results, samples taken from March 2, 2026 to March 2, 2026.

Above the legal limit1

Nitrate

Comes from the source

Above the legal limit

12.7ppm

One sample

2026, one sample: 12.7 ppm

One sample, in 2026, was above EPA’s legal limit of 10 ppm, at 12.7 ppm. No follow-up sample at that point within 30 days is on file. That is the only year on file, and its one sample was 12.7 ppm, above the limit. EPA recorded a violation for nitrate at this utility in 2026.

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

Arsenic

Comes from the source

Above the health goal

6.6ppb

Highest yearly average, 2026

Averaged by year, the highest was 6.6 ppb, in 2026: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That is the only year on file.

What handles it

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

Uranium

Comes from the source

Above the health goal

9.5ppb

Highest yearly average, 2026

Averaged by year, the highest was 9.5 ppb, in 2026: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file.

What handles it

Below EPA’s limits2

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.88ppm

Highest yearly average, 2026

Averaged by year, the highest was 0.88 ppm, in 2026, below EPA’s legal limit of 4.0 ppm. That is the only year on file.

What handles it

Chromium (total)

Comes from the source

Below EPA’s limits

1.4ppb

Highest yearly average, 2026

Averaged by year, the highest was 1.4 ppb, in 2026, below EPA’s legal limit of 100 ppb. That is the only year on file.

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), Arsenic (Pentavalent)<=50 ppb Reduction

    For: Nitrate, Arsenic

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

  • NSF/ANSI 58

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

    For: Nitrate, Arsenic, Uranium

    Other certifiers’ wording: Nitrate; 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. Nitrate, arsenic, uranium, fluoride and chromium (total) results here are Texas’s own from 2026 on, with EPA’s national file for 2012 to 2019. Walle World Rv 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 March 2, 2026 to March 2, 2026.

Testing your own tap

Walle World Rv 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 Walle World Rv Park serves on the state’s list. Some take samples by mail; the state’s page lists them all.
