PRIMA ENVIRONMENTAL FIELD METHODS FOR BENCH TEST ANALYSIS
<br /> ' Task 1 - Characterization of Soil and Water
<br /> ' Untreated soil will be homogenized prior to testing and analyzed for the following:
<br /> CDCs and potential breakdown products (TPHg, TPHd, BTEX, MTBE, acetone, TBA),
<br /> Cr(VI), and metals (Al, Sb, As, Ba Be, Cd, Ca, Cr, Co, Cu, Fe, Pb, Mg, Mn, Hg, Mo, Ni,
<br /> K, Se, Ag, Na, TI, W, V, and Zn).
<br /> Groundwater will be analyzed for: CDCs and potential breakdown products (TPH-g,
<br /> ' TPH-d, BTEX, MTBE, acetone, TBA), alkalinity, chloride, conductivity, Cr(VI), metals (Al,
<br /> Sb, As, Ba Be, Cd, Ca, Cr, Co, Cu, Fe, Pb, Mg, Mn, Hg, Mo, Ni, K, Se, Ag, Na, TI, W, V,
<br /> and Zn), nitrate, ORP, pH, sulfate, and total dissolved solids (TDS)
<br /> ' The method for each analysis and the laboratory to perform the analysis are given in
<br /> Table 2.

<br /> Task 2— Ozone Demand
<br /> The ozone demand of soil and groundwater will be estimated using methods based on
<br /> the "Ozone Demand" tests described in Standard Methods for the Examination of Water
<br /> and Wastewater, 19"' Ed.
