No health-based violations on file since 2016. EPA lists 1 monitoring or reporting violation, which are paperwork and testing lapses rather than water quality findings.
What was found, stop by stop

- Above the health goal

At the source
EPA’s UCMR 5 did not sample this utility, so there are no federal PFAS or lithium results for it. Its own annual report lists what it tests for.
In treatment
No federal results for this stop. Disinfection byproduct, chlorine and fluoride levels are in East Montgomery County MUD 6’s own annual report, which it must send you every year.
In the pipes
No lead and copper results on file with EPA for this utility.
At your tap
The last stretch is your own plumbing. A certified lab test is the only way to know what reaches your glass. Lead in your water: what to do
Tested and not found

The one compound tested and not found
- Lead
Violations since 2016
No health-based violations on file with EPA since 2016. There is 1 monitoring or reporting violation: a sample missed, late or not reported.
What this report cannot tell you
- Levels of everything else. Federal bulk data carries results for PFAS, lithium, lead and copper, and violations for the rest. Nitrate, arsenic, disinfection byproducts and other levels are in East Montgomery County MUD 6’s own annual report, which it must send you every year.
- 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.
- Anything after the latest data. SDWIS data is from 2026 Q2; UCMR 5 samples are from no sampling at this utility.
