<br /> 3. All water produced from the well developments will be collected
<br /> in 55-gallon drums, labeled, covered and stored on-site for later
<br /> disposition contingent on analytical results of the water samples.
<br /> Disposal of the developed waters will conform to applicable
<br /> hazardous waste requirements and will, at no time, be stored on
<br /> site more than 60 days after the time of initial placement in the
<br /> drums. Figure 7 depicts a suitable drum label THE ENVIRONMENTAL
<br /> CONSTRUCTION COMPANY uses in all their groundwater projects.
<br /> SAMPLE HANDLING AND PRESERVATION
<br /> 1. All chemical sampling, handling, and storage will be conducted
<br /> In accordance with Regional Water Quality Control Board guidelines
<br /> for the investigation of suspected underground storage tank leaks.
<br /> i
<br /> 2. In the field, all sample containers will be properly sealed,
<br /> labeled and identified. Included in the label will be the date,
<br /> sampling time, identification number, sample depth, project name,
<br /> and analytical method requested, IAD example of a completed sample
<br /> label is shown in the attached Figure 4.
<br /> 3. The samples will be delivered to a state-certified analytical
<br /> laboratory, Chromalab Inc. of San Ramon, California (Certification
<br /> # E 694 and # 955) within 3 working days of their acquisition.
<br /> Samples will be kept on ice and/or refrigerated continuously
<br /> before, during and after transport to the laboratory. Dry ice will
<br /> be used for all soil sample storage prior to transport to the
<br /> laboratory.
<br /> 4. Unless otherwise requested by the laboratory, no preservatives
<br /> will be added to the sample.
<br /> 5. The sealed sample will only be opened by laboratory personnel
<br /> who will perform the chemical analysis.
<br /> 6. The samples will analyzed within 14 days from their collection
<br /> date.
<br /> 7. A chain of custody form (Figure 5) will be properly completed
<br /> prior to relinquishment of the samples to the analytical
<br /> laboratory, This chain of custody form will include the site
<br /> address, project identification name and number, phone number and
<br /> name of consulting firm, sample identification, date and time of
<br /> sampling, matrix, preservation method, number and size of
<br /> containers, analysis requested,
<br /> SOIL SAMPLING FOR LABORATORY TESTING
<br /> 1. The soil sampling will commence at a depth approximately equal
<br /> J to the depth of approximately 15 feet below grade. The samples
