Request for Proposals for the Purchase of One Liquid Chromatography with Tandem Mass Spectrometry (LC-MS/MS) System for the Orange County Water District

The Orange County Water District (District) is soliciting proposals from qualified vendors to provide one LC-MS/MS system.


The District was formed in 1933 by a special act of the California State Legislature to protect Orange County's rights to water in the Santa Ana River and to manage this important groundwater basin.

Since 1933, the District has replenished and maintained the groundwater basin at safe levels while more than doubling the basin's annual yield. This important source provides local groundwater producers with a reliable supply of high-quality water.

This system must be fully compliant with EPA Method 533 and 537.1 for the determination of Per- and Polyfluorinated Substances, as well as emerging contaminants and other personal care products, pharmaceuticals, and hormones.
