Used samples are to be analyzed for metals, they may be placed in lahuralory-prepared clean glass jars. Soil should be cooled as iadtr:alcd under"preservaliun' and maximual holding limes apply to both soil and water urdess otherwise noted. ` For analysis in California,use California DIIS rcconunended procedure as presented in LUFf manual using gas chromatography with a flame ionization detector. In other slates,local requirements should be followed. ' hiclhod to be used in California Regional Water Quality Comtel Board North Coast and Central Valley Regions. In other areas,local requirements should be followed. ' If UPA hlnhuds 8010 and 8020 are to be ten in sequence, HCL may be added. Check with the project manager before adding acid. ' Chlowelhylvinylethcr may be detected at concentrations below 50 pans per billion due to degradation of HCL. Refelenees: II.S.
