Performance Work Statement (PWS) / Statement of Work (SOW) Automated Solid-Phase Extraction (SPE) system for PFAS sample analysis

DESCRIPTION: This Statement of Work (SOW) / Performance Work Statement (PWS) is for the purchase of an Automated Extraction system capable of automating sample preparation from soil samples for EPA Methods 3545A while meeting method background, recovery, and repeatability requirements. Purchase is intended to replace PFAS extraction equipment currently being for EPA Method 3545A and return PFAS extraction equipment to use for EPA Method 1633.

BACKGROUND: For this funding action, the Agency will receive: an Automated Extraction system capable of automating sample preparation from soil samples for EPA Methods 3545A while meeting method background, recovery, and repeatability requirements. Purchase is intended to replace PFAS extraction equipment currently being for EPA Method 3545A and return PFAS extraction equipment to use for EPA Method 1633. Instrumentation primarily used for extraction of voltile organic compounds from soil samples, but may also be used for extraction of other compounds of interest to the Region 9 laboratory in support of other divisions and regional projects. This purchase is mission critical because: the requested extraction equipment is to be used for the required extraction of volatile organic compounds from environmental soil samples prior to analysis, allowing the R9 lab to serve its Regional partners in this capacity. The equipment may also be used for projects involving emerging contaminants in the future. The cost of manual solid-phase extraction is expensive and time consuming. Having a dedicated Automated Extraction system capable of automating most of the sample preparation is the best practice for maximizing analyst’s time, reducing inter-laboratory contamination risks as well as manual errors and costly re-extractions, ensuring laboratory operational efficacy, and managing operational costs. This purchase would also allow the laboratory to reorient the more expensive PFAS safe Automated Extraction system back to PFAS sample preparation, further extending operational funds. This action supports laboratory operations that align directly with EPA Pillar 1: Clean Air, Land, and Water for Every American. There are no anticipated congressional issues as this purchase directly supports EPA’s statutory obligations under: Safe Drinking Water Act (SDWA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Additionally, no redundancy with federal employees will occur with this purchase. In summary, this purchase addresses an appropriate, mission critical, real need and as such demonstrates a reasonable use of taxpayer resources.

SCOPE: This item description establishes the minimum requirements for the purchase of a commercially available an Automated Extraction system capable of automating sample preparation from soil samples for EPA Methods 3545A while meeting method background, recovery, and repeatability requirements. All necessary components and materials for a complete Automated Extraction system will be included with the following salient characteristics.
