<br /> certified laboratory for the following constituents:
<br /> • TPH-g and TPH-d in accordance with EPA Method 8015M;
<br /> • Volatile organic compounds (VOCs): BTEX and fuel additives DIPE, ETBE, MTBE,
<br /> TAME,TBA, EDB, and 1,2-DCA in accordance with EPA Method 8260B.
<br /> • General Minerals(metals;Al,Sb,As,Ba,Be,Ca,Cd,Cr,Co,Cu,Fe,Pb,Mg,Mn,Hg,Mo,
<br /> K, Ni, Ag, Na, Se, Tl, W, V, and Zn) by EPA Method 200.8 and Hexachrome by EPA
<br /> Method 218.6;
<br /> • Metals including antimony, arsenic, bromide, bromate, barium, beryllium, cadmium,
<br /> calcium, chromium, cobalt, copper, iron, lead, mercury, magnesium, manganese,
<br /> molybdenum,nickel,potassium,selenium,silver,sodium,thallium,vanadium,and zinc by
<br /> EPA Method 200.8,and hexavalent chromium by EPA Method 218.6/DISTLC/3060A;
<br /> • General Minerals(anions: Cl,F,N031SO4, and others)by EPA Method 300.1;
<br /> • pH by EPA Method 150.1, specific conductivity by EPA Method 120.1,natural oxidation
<br /> demand as chemical oxygen demand(COD)by EPA Method 410.4;
<br /> • For water only: oxygen reduction potential(ORP)by SM 2580B,alkalinity by EPA Method
<br /> 310.1, and total dissolved solids (TDS) by EPA Method 160.1., organic carbon and soil
<br /> oxidation demand will be included in the soil analysis by SM (EPA) Method 5220D/
<br /> 53310B.
<br /> The lowest practical reporting and detection limits will be attempted during the course of chemical
<br /> and physical analysis for the soil and ground water samples.
<br /> In addition, during purging of the wells for ground water sample collection, purge water will be
<br /> measured for pH,specific conductivity,temperature,dissolved oxygen(DO),and ORP.Laboratory
<br /> reports for soil and ground water analysis,testing methods,laboratory QA/QC reports,and sample
<br /> chain of custody documentation will be presented in a report with findings and recommendations.
<br /> 3.5.2. Ozone BST Laboratory Procedures
<br /> The Ozone BST will consist of assessing soil and groundwater samples collected from the 60 to 100
<br /> foot saturated zone. For the Ozone BST, a minimum of 2,000 grams (4.4 pounds) of soil and
<br /> 2,500 milliliters (ml) or 0.66 gallons of the ground water will be required for each evaluation.
<br /> However,the analytical laboratory recommends that each set of soil samples consist of four 2-inch
<br /> by 6-inch brass sleeves; and each ground water sample consist of 6 liters. The Ozone BST will be
<br /> conducted by the laboratory for a total of five days.An ozone generator will be utilized to produce
<br /> Advanced GeoEnvironmental,Inc.
