Kennedy Mine Tailings Wheel Park (TEA project)

Project Profile
Kennedy Mine Tailings Wheel Park (TEA project)
Location: Jackson
Owner: City of Jackson
Total Project Value: Unknown
Consultant/Engr. Cost: $3,500
Square Footage/Area: < 1 acre
Completion Date: 1999

The historic gold mine transfer structures for mill-tailings were preserved in the City of Jackson recreation area. The wheel house foundation areas had potential to contain hazardous materials due to mine mill tailings that had spilled from wheel operation and accumulated at the base of the wheels.

The City charged Stratus personnel to conduct Phase I and II environmental assessments to fulfill state special-project funding requirements.

Project Challenges

Concentrations of heavy metals were reported from laboratory analyses of the mill tailings during the assessment. The laboratory results indicated the materials would be classified by state regulating agencies as Designated Waste possibly requiring costly excavation, transportation and disposal at a Class II landfill.

Stratus Solutions

The potential existed for metal constituents to leach from the tailings into the area’s groundwater or be wind-borne or scattered onto adjacent properties. Stratus personnel recommended an in-place cement treatment of mine mill tailings at the base of the tailings wheels to bind the metals-laden sand into a solid inert cement mixture. This solution provided an alternative to avoid costly excavation, transportation and disposal.
