Sample Submission Guidance & Procedures
The NC DWQ Laboratory Section Sample Submission Guidance Document is designed to provide a uniform set of procedures for sample submission to the NC DENR/DWQ Laboratory Section. The protocols outlined in this document are applicable to parties responsible for the collection, handling, field screening, documentation, packaging, shipping and receipt of samples. Efforts to improve current procedures will continue and this document will be revised, as needs dictate. Similar procedures should be followed when submitting samples to the DWQ laboratory located in the Asheville Regional Office.
Four factors that may ultimately affect the integrity of reported data include: 1) obtaining a representative sample, 2) preventing contamination of the sample, 3) providing legal documentation of the sampling event, and 4) protecting the sample from chemical, physical or biological change prior to analysis.
