2017 Split Sampling Summary Now Available

Each year, the SWP carries out split sampling at permit required monitoring sites at the Eagle Mine site and the Humboldt Mill (groundwater, surface water, and facilities) in conjunction with Eagle Mine’s scheduled monitoring. Split sampling is when a sample taken from a single source (ex. a groundwater well) is divided in two, with each sample analyzed by a different certified laboratory. The objective of the split sampling is to verify that  independent lab results corroborate and are representative of environmental conditions. A summary of the split sampling results from 2017 is available here.

CEMP and KBIC Partner to Monitor Water Quality in the Headwaters of the Salmon Trout River

During 2017, CEMP in cooperation with the Keweenaw Bay Indian Community (KBIC) began water quality monitoring at 8 sites in the headwaters of the Salmon Trout River. The headwaters of the Salmon Trout River begin as “seeps” or natural springs at locations where groundwater daylights and becomes surface water (see map of sites). Results of the monitoring will be used to assess potential impacts from mining activities to the Salmon Trout River.  Please contact SWP for questions or comments on the additional monitoring locations at (906) 228-6095 ext. 13, or geri@superiorwatersheds.org.

New CEMP Groundwater Monitoring Well Installed Near Eagle Mine

On August 30, 2017, the SWP Community Environmental Monitoring Program (CEMP) installed a new groundwater monitoring well northeast of Eagle Mine to better understand the mine’s potential impact on groundwater quality and the Salmon Trout River. The new well, located between the mine and the headwaters of the East Branch of the Salmon Trout River, will monitor groundwater quality at a depth of 175 feet.
