Task 5: Matrix Design

5.1 Soil Matrixes Design and Test  The team proposes three different Matrix designs 5.2 Design Modification  Best two designs will be modified for optimization 5.3 Optimal Matrix Design  Optimize final design 6.1 Final Design Testing-Contaminate Removal

• Contaminate testing before and after

flow through matrix
