Community Environmental Monitoring Program


The Keweenaw Bay Indian Community (KBIC) recently partnered with the Superior Watershed Partnership (SWP) and the Community Foundation of Marquette County (CFMC) to collaboratively conduct the Community Environmental Monitoring Program (CEMP), an independent monitoring program of Eagle Mine operations. The CEMP Technical Committee (Eagle Mine, SWP, and KBIC) meets monthly to share updates, review monitoring results and discuss outreach plans and additional monitoring requests/special studies. The CEMP Policy group (Eagle Mine, SWP, KBIC, and CFMC) meets quarterly to discuss CEMP Agreement timelines and other program issues/opportunities. This partnership allows KBIC to share stewardship responsibilities and first treaty obligations with other communities, and to learn more about world views.


The CEMP program began in 2012 and provides an independent and comprehensive picture of groundwater quality, surface water quality, air quality, plant life and more. To date, the program has focused primarily on Eagle operations at the mine site, the Humboldt Mill and along the designated transportation route. KBIC Natural Resource Department (NRD) technical staff are working with SWP staff to prioritize and conduct all facets of CEMP monitoring and reporting.

Prior to partnering on the CEMP program KBIC had requested that SWP include additional CEMP monitoring for unique sites such as groundwater seeps and traditional tribal foods such as blueberries and wild rice. KBIC and SWP have a long history of collaborating on other initiatives including environmental restoration projects and a summer conservation program for tribal youth. The Community Foundation provides an independent administrative and coordination role in addition to assisting with community outreach.

Eagle Mine is located in the Lake Superior watershed and straddles the headwater regions of the Salmon Trout River and Yellow Dog River. The Humboldt Mill is located in the Lake Michigan watershed where treated water from the Humboldt Tailings Disposal Facility (HTDF) is discharged to the Middle Branch of the Escanaba River. CEMP utilizes EPA-approved independent laboratories to analyze monitoring samples collected from hundreds of sites in and around Eagle Mine, Humboldt Mill and the transportation route. The CEMP program consists of four main components: 1) Verification Monitoring, which includes verifying the environmental monitoring conducted by Eagle Mine as required by state permits, 2) Additional Monitoring, which includes environmental monitoring done by SWP and KBIC over and above required state permit monitoring, 3) Publication of Monitoring Results, and 4) Community Outreach. All historic and current CEMP monitoring data can be viewed on the CEMP website.

KBIC becomes part of most recent CEMP agreement (The Mining Journal)



Operated in cooperation with KBIC and other partners, the U.S. Geological Survey (USGS) supports the collection and delivery of both streamflow and water-level information for five local sites. The data are served online - most in near realtime.

Current data typically are recorded at 15- to 60-minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. See local site information and more general information about the network below:
