4 public water systems serve this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.
CITY OF DENTON
PWSID TX0610002 · TX · serves 150,037 people
PFAS and lithium
5 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 19 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 10 µg/L | 1 | 10/23/2023 |
| PFBA | 0.0089 µg/L | 7 | 7/10/2023 |
| PFHxA | 0.0058 µg/L | 4 | 7/10/2023 |
| PFPeA | 0.0057 µg/L | 4 | 7/10/2023 |
| PFBS | 0.0047 µg/L | 3 | 7/10/2023 |
A detection is a measurement, not a violation and not a health finding. EPA states that UCMR 5 results do not indicate compliance or non-compliance with any limit.
Health-based violations
No open health-based violation on record. This covers MCL, treatment technique and MRDL violations in SDWIS that have not been returned to compliance. It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.
Hardness
No hardness measurement. Hardness is measured at environmental monitoring stations, and none fell inside this system’s service area. That is a gap in where monitoring happens, not a finding about the water.
BOLIVAR WSC
PWSID TX0610049 · TX · serves 11,901 people
PFAS and lithium
1 compound detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 30 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 57 µg/L | 30 | 4/7/2025 |

Hardness
Too few readings to state a hardness. 1 station(s), 120 result(s). Below two stations and five results this page will not state a number: a median of two readings from one creek is not your water.
TOWN OF PONDER
PWSID TX0610039 · TX · serves 2,711 people
PFAS and lithium
Not sampled for PFAS. EPA’s UCMR 5 monitoring covered every system serving more than 3,300 people and only a sample of smaller ones. This system was not in it, so there is no result to show, which is not the same as a result showing nothing.

What this report cannot tell you
Every figure describes water at a sampling point: a treatment plant, an entry point to the distribution system, or a monitoring station. None of it describes water arriving at your tap. Plumbing between the two can add lead and copper, and if your home was built before 1986 a test kit tells you something no federal dataset can.
