Onslow Water & Sewer Authority's laboratory is responsible for all of the system's compliance sampling needs to ensure our water quality meets or exceeds all EPA and North Carolina Department of Environment and Natural Resources requirements.

Our Mission
The Laboratory Department will support ONWASA's efforts by performing analysis of inorganic, microbiology and organic parameters utilizing a quality control and assurance program (QC/QA) as specified by regulating entities. 

Where the laboratory cannot perform the analysis for a given parameter, a commercial laboratory meeting the requirements specified in the QC/QA manual will perform the analysis.

ONWASA produces an Annual Water Quality Report which lists and describes all sampling conducted in that year and the results of the analysis.
