BACKGROUND

The purge and trap gas chromatographic / mass spectrometer (P&T GC/MS) system is used for determining volatile organic compounds in wastewater and industrial wastewater via EPA Method 624. This system is required to support compliance testing as required by the Orange County Sanitation District's (Sanitation District) NPDES permit. The system is also used to provide testing required by the Sanitation District's Resource Protection Division. Additionally, the lab has added the analysis of 1,4-dioxane using the P&T GC/MS system in to support the GWRS and other 1,4-dioxane projects since October 2012.

RELEVANT STANDARDS

* Ensure the public's money is wisely spent
* Comply with environmental permit requirements
* Maintain a culture of improving efficiency to reduce the cost to provide the current service level or standard
* Cultivate a highly qualified, well-trained, and diverse workforce

The instrument downtime has increased due to its age and the additional samples being analyzed. Higher maintenance of the current P&T GCMS has increased the cost the keeping it in operation particularly relating to parts availability and service maintenance cost. Purchasing a replacement P&T GC/MS system would provide the lab with a more reliable system with current tech...
