Precision Plating Superfund Bench Scale Study Services

The vendor required to provide Remedial actions for the site include in-situ treatment of remaining chlorinated volatile organic compound (CVOC) contaminated soils with in-situ chemical reduction (ISCR) or oxidation (ISCO) and solidification and stabilization (ISS) amendments as well as metal stabilization amendments.
•    Conduct baseline analyses of site soil for CVOCs, metals, applicable general chemistry parameters, and laboratory parameters. 
•    Conduct baseline analyses of site groundwater for CVOCs, applicable general chemistry parameters, and laboratory parameters. 
•    Conduct a batch or column treatability study to evaluate the potential impact of ISCR amendments on site soil and the smear zone. 
•    Conduct three to five separate studies with mixed doses of ISCR amendments ranging from 0% to 3% or as recommended by the vendor. 
•    For each column tests, effluent water collected post treatment column will be tested for potential of hydrogen (PH) and oxidation reduction potential (ORP) on days 7, 14, 28, 56, and 84, and for CVOCs, total organic carbon (toc), and ferrous iron on days 28, 56, and 84.
•    After the study is complete, analyze soil from each column for final CVOC concentrations and general chemistry analysis.
•    Conduct an ISCO and ISS treatability study to evaluate the potential impact of ISCO and ISS with amendments on site soil and smear zone. 
•    Conduct analysis to determine soil-specific soil oxidant demand and base buffer capacity. 
•    Conduct three to five tests to be performed using varying dosages of ISCO and stabilization amendments to evaluate the effectiveness of various reagent blends for contaminant destruction, hydraulic conductivity (1.0×10−6 cm/s or less), unconfined compressive strength (40 to 50 psi), and contaminant leachate (to meet concentrations below agency health risk levels (HRLS). 
•    Amended soils from each batch condition should be sampled for compressive soil strength, hydraulic conductivity, and leachate testing synthetic precipitation leaching procedure (SPLP) or leaching environmental assessment framework (leaf) testing after 28 and 42 days. 
•    Soil strength to be measured using a pocket penetrometer 7 and 14 days after mixing. 
•    The test may be terminated at 28 days if treatment objectives are met.
•    Conduct a metal stabilization treatability study utilizing two to five different doses of metal stabilization amendments. 
•    After approximately 2 to 3 days of applying the amendments, the soil samples from each of the test conditions will be tested for metal leachability using toxicity characteristic leaching procedure (TCLP).
