TASK 1 – Mine Tailing Stabilization
Develop and demonstrate the remediation of a large tailings pile which is contaminating ground water and surface water with cadmium, copper, lead, arsenic, and zinc. The design must consider leaving the tailings in place in order to preserve the look of a historical mining district.

TASK 2 – Suppression and Immobilization of Radioactive airborne particulates.
Develop and demonstrate a suppression and immobilization process for particulates in plutonium contaminated gloveboxes.  The process is to be demonstrated on  8″X8″ stainless steel plates.  A surrogate will be used to simulate the radioactive particulate contamination.

TASK 3 – Innovative landfill closure cap
Develop an innovative cap system for solid waste landfills to meet the regulatory permeability standards for 30 years.  The full-scale design is to be modeled and verified using a bench-scale demonstration.

TASK 4 – Transuranic waste reduction
Develop and demonstrate a decontamination/destruction process to economically reduce TRU (transuranic) waste.  The process must be demonstrated on a variety of contaminated items (i.e. cheesecloth, rubber gloves,  vinyl tape, etc).  Non-radioactive surrogates will be used to simulate the contaminant.

TASK 5 – Pipeline waste removal
Develop and demonstrate a process for removal of a gelated plug in a waste pipeline.  The process could use chemical or other physical techniques (i.e. pressure/temperature variation, ultra-sonic vibration, etc.). However, avoid using removal tools such as roto-rooter.    The process will be demonstrated using a twenty-foot, 1 2″ – 2″ pipe, with open ends.

TASK 6 – In-situ soil decontamination
Develop and demonstrate in-situ soil remediation (preferably bio-remediation) of High Explosive (HE) and Research Development Explosive (RDX) in tight clay soils. The process must be demonstrated using soil samples packed into test cylinders which simulate natural permeability and porosity.

HS Tasks –
Task A – Innovative landfill closure cap for municipal solid waste landfills
Task B – Local Implementation of solid waste reduction
