4 <br /> Smith Technology Corporation <br /> Quality Assurance/Quality Control Plan <br /> Revised February 1995 <br /> evidence. Where several types of analysis will be performed for,a given well, individual samples will be <br /> collected in the following order: <br /> 1. Volatile Organics <br /> 2. Purgeable Organic Carbon <br /> 3. Purgeable Organic Halogens <br /> 4. Total Organic Carbon <br /> 5. Total Organic Halogens <br /> 6. Extractable Organics f <br /> 7. Total Metals <br /> 8. Dissolved Metals <br /> 9. Phenols <br /> 10. Cyanide <br /> j <br /> The specific analytical methods be utilized for the common volatile/semivolatile to analyses are shown ! <br /> on Table 2. <br /> I Groundwater samples will be collected with a teflon bailer with bottom emptying device. Duplicate <br /> samples will be transferred to vials or containers that meet Regional Board specifications (Table 1). <br /> Groundwater from the bailer will be transferred to the sample container by allowing the fluid to flow <br /> slowly along the sides of the vessel. All containers will,be filled above the top of the opening to form a <br /> positive meniscus. No headspace should be present in the sample container once it is sealed. After the <br /> vial is capped it will be inverted to check for air bubbles. If bubbles are present the sample will be <br /> discarded and replaced. If it is not possible to collect a sample!without headspace, the problem will be <br /> noted on the field technician's sampling log. <br /> Immediately following sample collection, samples will be labeled and stored in an ice chest containing <br /> k <br /> frozen chemical ice sealed in plastic bags. Sample labels will contain the following information: <br /> ✓ date and time ` <br /> W AAdminlShe11 s1QAQC-97.DOC <br /> 14 <br /> i <br />
