recommendation
RECOMMENDATION:
Approve a purchase order to VWR for a Purge & Trap Gas Chromatograph-Mass Spectrometry (GC-MS) System in the amount of $115,226 plus applicable sales tax, which includes the GC-MS system, freight, and three (3) additional years of service at a discounted rate.

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
