Z -- CONTAMINATED SOIL REME- DIATION, AMMO DEMO AREA & MISC SITES UMAT ILLA DEPOT HERMISTON, OREGON SOL DACA67-95-R-0037 DUE 060895 POC Contact, Rose Porcincula, (206) 764-3653 The work involves cleanup of metals and explosives contaminated soil. The contaminates of concern are lead cadmium, chromium, trinitrotoluene (TNT) and Royal Demolition Explosives (RDX). The depth of contamination is from the surface to as much as 10 feet deep. An estimated quantity of 8,600 cubic yards of contaminated soil will be excavated, treated by solidification/stabilization (S/S) mix plant operation, and disposed in a solid waste landfill on the Umatilla Army Depot. To the extent possible unexploded ordnance will be cleared from the soil sites within an Ammunition Demolition Area (ADA) by others. Residual ordnance and explosive waste scrap may remain at the ADA sites and will require the Contractor to provide an explosives ordnance safety specialist during an estimated 7,500 cubic yards of soil remediation. Gravel soil fractions will be processed by screening, crushing and washing with water prior to S/S. The Contractor will prepare a S/S mix design and perform a full- scale demonstration test of the approved mix prior to production S/S. Field screening using x-ray fluorescence techniques and laboratory analysis for metals will be conducted to verify contaminated soil removal to the required level for lead, cadmium, and chromium. Field screening using EPA Method 8515 and 8510 for TNT and RDX and laboratory EPA method 8330 to verify explosives soil removal. Field and laboratory tests will be conducted to control the material properties of the S/S mix. The treated soil will be required to pass the appropriate RCRA regulatory limit for metals and explosives by the Toxicity Characteristic Leaching Procedure (TCLP). Demolition, decontamination and disposal in the depot landfill of a 15 foot by 30 foot by 12+inch thick reinforced concrete slab is also included in this work.
