Sample Submission Guidance
The Water Sciences Section's Chemistry Laboratory maintains a Sample Submission Guidance Document that is designed to provide a uniform set of procedures for sample submission to the WSS Central and Asheville 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.

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.
