Sample Submission Guidance
The Water Sciences Section's Chemistry Laboratory Sample Submission Guidance Document is designed to provide a uniform set of procedures for sample submission to the WSS Central and Regional Laboratories. 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.
Sample Collection and Submittal Guidance Documents:
Sample Collection & Submittal Forms (Field Sheets):
The following forms are to be used by DWR sample collectors when submitting samples to the WSS Central Laboratory and Asheville Regional Laboratory.
The following guidance is provided regarding sample submission for time-sensitive parameters (see table below; hold times of 48 hours or less) to the Central Laboratory in Raleigh and Regional Laboratory in the Asheville Regional Office. Prior to submitting samples for these parameters, please review the guidance document and Sample Submission Restriction Calendars (for state holidays) below:

Purpose of these Documents and Forms:
The primary goal of these documents is to promote the use of procedures that will ensure that data reported by the laboratory is accurate as well as legally and technically sound. Errors in environmental analysis can result from incorrect sampling handling or lack of supporting documentation.
Factors that may ultimately affect the integrity of reported analytical data include:
The WSS Chemistry Laboratory 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.
