Three Michigan systems, reports covering 2025
Grand Rapids · MI0002790
Lake Michigan and separate lead and PFAS sections
Grand Rapids’ 2025 report identifies Lake Michigan as the source treated for its water system.
The report separately discusses known or presumed lead service lines, a lead sample above the action level, and PFOS results. The short report overview is an entry point to those sections, rather than a summary of every sample or condition at a home.
Sterling Heights · MI0006385
Purchased GLWA water from the Lake Huron watershed
Sterling Heights’ 2025 report describes purchased water supplied by the Great Lakes Water Authority, with source water from the lower Lake Huron watershed. The City’s distribution system and its wholesale supplier have different roles.
Keep the report’s service-line inventory statements, lead and copper testing, and special-monitoring results with their dates. A reported inventory total cannot establish the current pipe material or water result at an individual property.
Lansing · MI0003760
Saginaw Aquifer groundwater
Lansing Board of Water & Light’s 2025 report describes 112 groundwater wells in the Saginaw Aquifer. This is the report’s system-level source description.
The document includes 2023 lead and copper results, a 2026 sampling schedule, and other results from different years. Its statements about lead-service-line work and PFAS belong to the report’s scope; they do not establish current household conditions.

Sources, methodology, and limitations

Review methodologyMichigan context
Great Lakes water and groundwater serve different systems
Source comparison
Follow the system’s source description
Grand Rapids’ report describes Lake Michigan, Sterling Heights’ describes purchased GLWA water from the lower Lake Huron watershed, and Lansing’s describes Saginaw Aquifer groundwater.
These examples do not provide statewide source shares or identify the source serving an address. A city name or proximity to a lake is not enough to confirm a supplier.
Supplier roles
A wholesale supplier is separate from the local system
Sterling Heights’ report combines GLWA treatment and source context with local distribution-system results. Check which organization and sampling location a section describes before comparing it with another system.
Review dates
Older tables remain older measurements
These selected system profiles retain their August 9, 2026 review date. This state guide’s source review was September 13, 2026; it does not refresh their samples or current-notice status.
For example, Lansing’s 2025 report includes a 2023 lead-and-copper table. The report cover year does not change the date of that sampling.

System identity
Start with the provider and PWSID
The selected records are Grand Rapids MI0002790, Sterling Heights MI0006385, and Lansing Board of Water & Light MI0003760. EPA’s public identity record separately identifies GRAND RAPIDS as MI0002790.
- Compare the supplier name on your water bill with the provider’s official report page.
- Keep the exact public water system ID with the report. For Grand Rapids, the official municipal report and EPA identity record work together to identify MI0002790.
- If the name or service relationship is unclear, ask the provider to confirm the PWSID and whether it supplies your address.
EGLE program
Use the right agency resource
Michigan’s Department of Environment, Great Lakes, and Energy oversees community water supplies through its Community Water Supply program. Its page links consumer confidence reports, public-notification information, lead and copper resources, PFAS information, and contacts.
MiEHDWIS is described as a workspace for regulated entities to submit information, with business-account access. Residents looking for a report can use the provider archive or EGLE’s public program resources.
Official resources
Michigan report, service-line, and notice resources
Lead and service lines
Understand Grand Rapids’ inventory map
Grand Rapids’ map instructions say to zoom to a property and open the circle for its service-line material record. The guidance distinguishes records and assumed material; it also describes a separate replacement-scheduling indicator.
Use the City’s instructions and ask the provider to confirm uncertain information. An inventory entry does not supply a tap-test result, and a replacement schedule can change.
PFAS
Read results with the compound and sampling period
Grand Rapids provides a dedicated PFAS page alongside its annual report. The report’s PFOS row is separate from its other monitoring results.
Use the compound name, sampling date, unit, and result-column label together. A range maximum and a separately labeled reported value are not interchangeable, and a system result does not determine exposure at a home.
Current instructions
Go to the provider’s notice destination
Grand Rapids links water-quality resources and emergency-alert registration. Sterling Heights provides City Alerts connections, and Lansing BWL provides an outage-center alert surface.
A subscription or outage page does not establish that every water notice has been found. Check your own provider’s latest notice for the affected area, issue date, and instructions.

Lead questions
Ask Lansing BWL about testing and inventory records
BWL’s lead-information page discusses its earlier service-line replacement work, lead-and-copper sampling, and material-inventory verification. These are different kinds of evidence.
For a question about your service line or testing, use the provider’s current guidance. A historical replacement milestone does not determine materials inside a building or a present tap result.
Private wells
Use Michigan’s private-well testing pathway
EGLE’s private residential well-testing page directs owners to listed local health departments or the EGLE Laboratory for test kits. It also provides sampling guidance and a route to interpret laboratory results.
Start with the health-department or laboratory instructions for your location and question. A nearby city’s annual report cannot characterize a private well.
Michigan questions
Questions raised by these reports
Purchased water
Why does Sterling Heights’ report discuss GLWA?
The City purchases treated water from the Great Lakes Water Authority. The report includes supplier treatment and source context alongside local distribution information; keep those roles distinct.
Sampling dates
Are Lansing’s lead results from 2025?
The lead-and-copper table in the 2025 annual report is labeled 2023. The same document describes a 2026 sampling schedule. Neither the cover date nor the schedule supplies a new sampling result.
Inventory records
Does a service-line map tell me what is in my tap water?
No. Grand Rapids’ inventory guidance concerns recorded or assumed pipe material. A laboratory sample concerns water collected at a particular place and time. Use the provider’s guidance to follow up on either question.
Report access
What if a Michigan annual-report link fails?
Start from the official provider archive and request the report title and monitoring year, including an accessible copy if needed. Grand Rapids, Sterling Heights, and Lansing BWL publish their reports on different sites.
