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.

United States Forest Service Riley Pass Abandoned Uranium Mine

 

The United States Forest Service is conducting a Superfund (CERCLA) non-time critical removal action to address metals and radioactive mine waste contamination coming from the Riley Pass Abandoned Uranium Mine. The mine is located on U.S. Forest Service property approximately 25 miles north of Buffalo, South Dakota in the North Cave Hills. The localized contamination is a result of uranium strip mining that occurred in early 1960's. The goal of the Forest Service's current actions at the site is to remove or reduce any exposure to the contaminated surface material.
