U.S. Forest Service

United States Forest Service – Nemo, SD

 

 The United States Forest Service is conducting a Superfund (CERCLA) non-time critical removal action to address groundwater contaminated with pesticides near the Nemo Work Center located in Nemo, South Dakota.  The U.S. Forest Service was trying to control bark beetle infestations through the use of pesticides in the 1970’s.  The mixing and handling practices of the pesticides at the Nemo Work Center resulted in spillage that has reached private drinking water wells in the Nemo area.  The Superfund non-time critical removal action underway includes providing clean drinking water to the impacted parties, a pump and treat remediation system to clean the groundwater, and groundwater monitoring to evaluate to the size and movement of the contamination plume.
