5 public water systems serve this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.

HIGH POINT WATER SUPPLY CORPORATION

PWSID TX1290016 · TX · serves 16,341 people

PFAS and lithium

2 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 4 samples.

CompoundHighest detectedSamplesMost recent
PFBA0.0093 µg/L33/21/2023
PFHxS0.003 µg/L13/21/2023

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.

Hardness

We do not state a hardness for any system, and this is why. Hardness here would come from environmental monitoring stations that happen to sit inside your water system’s service area. We checked that method against the figures twenty large utilities publish about their own supply: it agreed with the utility fewer than half the time, and where it was wrong it usually read HIGH. Cities supplied from a distant watershed came off worst, because the stations end up sampling local groundwater nobody drinks. We are paid a referral fee when somebody asks for an installer, so a number that overstates hardness is the last error we are willing to publish. Your utility publishes its own hardness in its annual water quality report, and that figure is the one to trust.

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.
