Purgeable organic halogens 4 Total organic carbon] r 5 Total organic halogens 4 b Extractable organics 7 Total metals ;w 8 Dissolved metals 9 Phenols C 10 Cyanide r K The specific analytical methods be utilized for the common volatile/semivolattle to analyses are ` shown on 'fable 2 3 Groundwater samples will be collected with a teflon bailer with bottom emptying device Duplicate samples will be transferred to vials or containers that meet Regulatory Agency r specifications(Table 1) Groundwater from the bailer will be transferred to the sample container by allowing the fluid to flow slowly along the sides of the vessel All containers will be filled above the top of the opening to form a positive meniscus No head space should be present in } the sample container once it is sealed After the vial is capped it will be inverted to check for ` air bubbles If bubbles are present the sample will be discarded and replaced. If it is not 4 possible to collect a sample without head space, the problem will be noted on the field technicians's sampling log Immediately following sample collection, samples will be labeled and stored in an ice chest s t containing frozen chemical ice sealed in plastic bags Sample labels will contain the following information, date, time, project ID, sample ID, name of sampler and type of analysis All samples will be transported udder chain-of-custody protocol to a state certified laboratory within 24 hours A sample container filled in the laboratory with organic free water and carred 4 �
