PWSID MD01700192026 edition · EPA data

Read this first

  • Lithium was found in six of 12 samples, highest 11 ppb. Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.

No health-based violations on file since 2016. EPA lists 4 monitoring or reporting violations, which are paperwork and testing lapses rather than water quality findings.

What was found

Highlighted: above the health goal. Circled: above the legal limit in at least one sample. Every scale puts the legal line at its middle.

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 Stevensville’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 Jan. 14, 2025 to July 15, 2025.
