1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Arsenic, above the legal limit. 3 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1995 to 2024.

Arsenic, nitrate, fluoride, chromium (total), haloacetic acids (HAA5), total trihalomethanes (TTHM) and uranium: Texas’s own results, samples taken from Dec. 7, 2020 to Sept. 14, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Arsenic

Comes from the source

Above the legal limit

11.6ppb

Highest yearly average, 2022 to 2026

2026 average: 6.8 ppb

Averaged by year, the highest was 11.6 ppb, in 2023, above EPA’s legal limit of 10 ppb. Its highest single sample was 13.8 ppb. In 2026, the latest year on file, its three samples averaged 6.8 ppb.

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

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

0.6ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 0.6 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.

What handles it

Below EPA’s limits2

Nitrate

Comes from the source

Below EPA’s limits

3.5ppm

Highest sample; found in 7 of 7

2026, one sample: 3.1 ppm

The highest sample, in 2020, was 3.5 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 3.1 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 3.4 ppm, in 2018.

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

0.14ppm

Highest yearly average, 2022 to 2025

2025, one sample: 0.12 ppm

Averaged by year, the highest was 0.14 ppm, in 2022, below EPA’s legal limit of 4.0 ppm. In 2025, the latest year on file, its one sample was 0.12 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.16 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)
  • Total trihalomethanes (TTHM)
  • Uranium

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: Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Arsenic, Lead

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

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. Arsenic, nitrate, fluoride, chromium (total), haloacetic acids (HAA5), total trihalomethanes (TTHM) and uranium results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Kitzwood Subdivision’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 Dec. 7, 2020 to Sept. 14, 2026.

Testing your own tap

Kitzwood Subdivision’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.
