Due to the complex nature of the waste matrix, a conservative experiment evaluated higher adsorbent mass loadings than the equilibrium predictions would normally specify. Samples were vigorously mixed using a magnetic stirrer for 48 hours. Samples were obtained for TCLP and the remaining solution was solidified using Water Works SP-400 (10 percent by weight). After waiting one day for solidification, the mass was tested for TCLP. The laboratory procedure incorporated SW-846 method 7471A requirements for solid samples on a Perkin Elmer FIMS CVAA instrument. Table 4 records that the laboratory was able to show that the sample results meet the TCLP limits for mercury provided the level of addition was greater than the amount predicted to absorb all of the mercury. isotherm after the organics were sparged. According to Table 5, this ratio should yield a TCLP value of about 0.037 mg/L, well below the limit of 0.20 mg/L. The materials were was added with an aqueous mixture of isopropyl alcohol, to increase its wetting potential in the aqueous V-9 waste. Table 5 summarizes the result of the V-9 treatment. All five samples easily met the treatment standard. Upon demonstration that the VOCs had also met their treatment standard through sparging, the waste was solidified for disposal at the Idaho CERCLA disposal facility.

Steward Environmental Solutions LLC is commercializing SAMMS adsorbents for a wide variety of heavy and precious metals, arsenic and selenium. SAMMS is a trademarked product of Steward Environmental Solutions. Water Works SP-400 is a product from Waterworks America. Final V-9 tank treatment Using the measured concentration of mercury (1.6 percent), the laboratory estimated that 13.5 pounds of mercury was in the V-9 tank, and determined to add 1.4 to 1.6 times the estimated mass of adsorbent predicted by the equilibrium adsorption References: 1. http://yosemite.epa.gov/r10/CLEANUP.NS F/6EA33B02338C3A5E882567CA005D382F/ INEEL/$FILE/ESD-ROD-TANOU1-10.pdf 2. www.epa.gov/epaoswer/osw/hazwaste.htm 3.
