OEOMATRIX TABLE 1 WATER AND SOIL ANALYTICAL METHODS AND SAMPLE HANDLING Parameter Method Water Containers' Preservation' Maximum Holding Time Total Petroleum Hydrocarbons: •as diesel GCFID(3 550)2 2- i liter amber glass cool on ice 14 days(unacidified water,7 days) •as gasoline GCFID(5030)2 2-40 ml VOA glass HCL to pH 2 in water samples: cool on ice 14 days(unacidified water,7 days) Benzene,Toluene,Xylene,and EPA 8020 2-40 ml VOA glass HCL to pH 2 in water samples: cool on ice 14 days(unacidified water,7 days) Ethylbenzene Volatile Organics with BTEX EPA 80213 2-40 ml VOA glass HCL to pH 2 in water samples: cool on ice 14 days(unacidified water,7 days) Oil and Grease 5520 E&F(Soil)4 2- I liter amber glass H2SO4 to pH<2 in water samples: cool on ice 28 days 5520 C&F(water)4 Volatile Organics EPA 8010 2-40 ml VOA glass cool on ice 14 days(unacidified water,7 days) EPA 82405 2-40 ml VOA glass HCl to pH 2 in water samples: cool on ice 14 days(unacidified water,7 days) Semi-volatile Organics EPA 8270 2- I liter amber glass cool on ice 7 days for extraction,water 14 days for extraction,soil 40 days for analysis Polynuclear Aromatic EPA 8310 2- 1 liter amber glass cool on ice 7 days,water Hydrocarbons 14 days,soil Metals(dissolved) EPA 7000 series for 1 - 500 ml plastic Water Samples: field filtration(0.45 micron filter) 6 months,except: specific metal and field acidify to pH 2 with HNO3 except:Cr+6- Hg-28 days cool on ice Cf 6-24 hours,water; 24 hours after prep,soil Notes: ' All soil samples should be collected in full,clean brass liners,capped with aluminum foil or Teflon and plastic caps,and sealed with tape. If soil samples are to be analyzed for metals,they may be placed in laboratory-prepared clean glass jars. Soil should be cooled as indicated under"preservation"and maximum holding times apply to both soil and water unless otherwise noted. 2 For analysis in California,use California DHS recommended procedure as presented in LUFT manual using gas chromatography with a flame ionization detector. In other states,local requirements should be followed. Method 3660M is silica gel cleanup. 3 EPA Method 8021 is equivalent to 8010/8020 in series. 4 Method to be used in California Regional Water Quality Control Board North Coast and Central Valley Regions. In other areas,local requirements should be followed. Method 5520F is silica gel cleanup. 5 Chloroethylvinylether may be detected at concentrations below 50 parts per billion due to degradation of HCl. EPA Method 8260B was formerly 8240. 6 If EPA Methods 8010 and 8020 are to be run in sequence,HCI may be added. Check with the project manager before adding acid.
