ISB Physical and Chemical Water Quality Monitoring SOP, Version 3.0

This manual contains the standard operating procedures (SOP) employed by the North Carolina Division of Water Resources (DWR) to evaluate water quality. It is intended to encompass all aspects of routine physical and chemical water quality monitoring with the occasional sediment samples. Therefore, this manual is to be considered a working, dynamic guideline for DWR personnel. Efforts to improve current procedures will continue, and the manual will be revised periodically, as needs dictate. Following the rewrite in February of 2026, this document was modified in MS Word meet accessibility standards and then converted to a pdf while maintaining structure tags.
