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.
