GENERAL MANAGER'S RECOMMENDATION
recommendation
RECOMMENDATION:
A. Approve a Purchase Order to Avantor (VWR) for the purchase of a Triple Quadrupole Inductively Coupled Plasma Mass Spectrometer (TQ-ICP/MS) System using NASPO Master Agreement No. MA2024005 for a total amount not
to exceed $328,000; and
B. Approve a contingency of $16,400 (5%).
body
BACKGROUND
The TQ-ICP/MS system will be utilized to analyze for trace metals in wastewater samples as required by Orange County Sanitation District's (OC San) National Pollutant Discharge Elimination System (NPDES) Permit and various special projects.
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
* Maintain a proactive asset management program
* Participate in local, state, and national cooperative purchasing programs
PROBLEM
This request is to augment the laboratory's analytical capacity and capability as it relates to trace metals in wastewater. Currently the laboratory performs compliance analysis for this class of compounds using a traditional single-quadrupole ICP/MS. The current instrument is almost eight years old and is approaching the manufacturer-recommended serviceable life of 10-12 years. The current instrument struggles to meet analytical sensitivity requirements outlined in the 2019 California Ocean Plan for constituents such as cadmium, copper, silver, and zinc.
PROPOSED SOLUTION
Approve a Purchase Order to VWR for the TQ-ICP/MS system to augment the current ICP/MS system. Purchasing the TQ-ICP/MS system will equip OC San with a more sensitive system that uses the most current technology, is less susceptible ...
