Quality Assurance/Quality Control Plan Page 12 <br />indicated by field evidence. Where several types of analysis will be performed for a given well, <br />individual samples will be collected in the following order: <br />1. <br />Volatile organics <br />2. <br />Purgeable organic carbon <br />3. <br />Purgeable organic halogens <br />4. <br />Total organic carbon] <br />5. <br />Total organic halogens <br />6. <br />Extractable organics <br />7. <br />Total metals <br />8. <br />Dissolved metals <br />9. <br />Phenols <br />10. <br />Cyanide <br />The specific analytical methods be utilized for the common volatile/semivolatile to analyses are <br />shown on Table 2. <br />Groundwater samples will be collected with a teflon bailer with bottom emptying device. <br />Duplicate samples will be transferred to vials or containers that meet Regulatory Agency <br />specifications (Table 1). Groundwater from the bailer will be transferred to the sample container <br />by allowing the fluid to flow slowly along the sides of the vessel. All containers will be filled <br />above the top of the opening to form a positive meniscus. No head space should be present in <br />the sample container once it is sealed. After the vial is capped it will be inverted to check for <br />air bubbles. If bubbles are present the sample will be discarded and replaced. If it is not <br />possible to collect a sample without head space, the problem will be noted on the field <br />technicians's sampling log. <br />Immediately following sample collection, samples will be labeled and stored in an ice chest <br />containing frozen chemical ice sealed in plastic bags. Sample labels will contain the following <br />information: date, time, project ID, sample ID, name of sampler and type of analysis. All <br />samples will be transported under chain -of -custody protocol to a state certified laboratory within <br />24 hours. A sample container filled in the laboratory with organic free water and carried <br />
