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.
body
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
PROBLEM
This request is to replace an aging system which is 10 years old and has exceeded the manufacturer serviceable life of 7-10 years. 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 technology and sensitivity needed to handle more samples so we can provide the best level of service for our customers.
PROPOSED SOLUTION
Approve a purchase order to VWR for the purchase of a Purge & Trap Gas Chromatograph-Mass Spectrometry (GC-MS) System in the amount of $115,226 plus applicable sales tax to replace the current system.
TIMING CONCERNS
Potential cost and down time may increase if the current system is not replaced in a timely manner.
RAMIFICATIONS OF NOT TAKING ACTION
Loss of EPA Method 624.1 California ELAP certification.
