Sample Submission Guidance & Documents
The DWR Laboratory Section Sample Submission Guidance Document is designed to provide a uniform set of procedures for sample submission to the NC DENR/DWR 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 DWR laboratory located in the Asheville Regional Office.

Factors that may ultimately affect the integrity of reported analytical data include:
The DWR Laboratory Section is committed to providing high quality data and excellent service in environmental analysis. To ensure that the results produced and reported meet the requirements of the data users and comply with state and federal regulations, a quality management system must be implemented that is clear, effective, well-communicated, and supported at all levels of the Division of Water Resources.
