SECTION 15
FINAL SAMPLE DISPOSITION
Upon completion of all required analyses and acceptance of the data reported, the
laboratory will be responsible for proper disposal of any remaining samples, sample
containers, shipping containers, and Styrofoam or plastic packing materials in
accordance with sound environmental practice, based on the sample analytical results.
Unused samples and containers found to be nonhazardous generally will be disposed
after 90 days following completion of the analysis. At 90 days, the laboratory will
contact the Project Chemist to obtain approval for the samples to be disposed. In cases
where the data package meets the project QA/QC requirements and no apparent
anomalies are present in the data set, the Project Chemist may authorize the laboratory to
dispose of the samples at an earlier date. The laboratory shall maintain proper records of
waste disposal and shall have disposal company contracts on file for inspection.
All raw and processed data generated during the analysis of project samples must be
stored for a period of five years. Revised copies of the applicable SOPs and QAPs must
also be maintained and available should the data be required. Should the laboratory go
out of business, all original records related to project samples shall be provided to project
personnel.
