PWSID MI0001990 · EPA data

Read this first

  • Lithium (above EPA’s health benchmark) was found in two of 2 samples, highest 17.5 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 2 monitoring or reporting violations, which are paperwork and testing lapses rather than water quality findings.

What was found

Highlighted: above the health goal, or EPA’s health benchmark where there is no goal. Circled: above the legal limit in at least one sample, or the action level. Every scale puts that line at its middle.

PFAS and lithium: EPA UCMR 5, samples taken from June 1, 2023 to Dec. 14, 2023. Each blue tick on a scale is one sample where it was found.

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 City of East Lansing’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 June 1, 2023 to Dec. 14, 2023.

    About Lithium

  • Get the utility’s own report

    City of East Lansing must send you a water quality report every year. It lists nitrate, arsenic and byproduct levels this page cannot.

    How to read it

  • Test your own tap for lead

    Your service line, solder and fixtures decide the lead at your faucet, not the utility’s average.

    Lead in your water: what to do

  • Decide if you want a filter at all

    A filter for taste or chlorine is a preference, not a need. The standards say what each kind can do.
