ACID VIALS

This Request for Quotation (RFQ 140G0226Q0178) is issued by the U.S. Geological Survey (USGS) to establish a single-award, open-market Blanket Purchase Agreement (BPA). The agreement is for supplying brand-name or equivalent acid vials containing pre-filled acid solutions. These supplies will support water sampling and testing activities for the USGS National Water Quality Laboratory (NWQL) and the Water Resource Discipline (WRD). The anticipated period of performance is September 21, 2026, through September 20, 2028, with a maximum ordering limit of $350,000.00. Individual purchases will be executed as firm-fixed-price call orders on an as-needed basis. This solicitation is not a small business set-aside and falls under NAICS code 325199. Contractors must meet strict chemical purity and containment specifications for three pre-filled solutions: nitric acid, sulfuric acid, and hydrochloric acid. Deliveries must be made FOB Destination to the Denver Federal Center in Colorado. Vendors must have an active registration in the System for Award Management (SAM) and submit invoices electronically via the Invoice Processing Platform (IPP). Final product acceptance is subject to QA testing by the NWQL.

This document outlines the Quality Assurance Surveillance Plan (QASP) for testing chemical vials managed by the Quality Assurance Section (QAS) of the National Field Supply Service (NFSS). The plan details the specific quality control procedures and lot acceptance criteria for three types of acid vials: Nitric Acid (HNO3, 7.5N), Sulfuric Acid (H2SO4, 4.5N), and Hydrochloric Acid (HCl, 6N). For each acid type, QAS personnel are instructed on sampling protocols based on whether the acid or container lot is new or previously approved. The testing workflow includes preparing control and test samples using Nanopure water in designated bottle types (such as FA, FCA, DOC, and FAM), labeling bottles for specific analytical methods (ICP/ICP-MS, nutrients, or carbon), and submitting them for "RUSH" laboratory analysis. Lot acceptance is determined by analytical reporting limits. If all sample data fall below these limits, the QAS analyst approves the lot for sale by notifying Support Services (SS). If potential contamination is identified at or above reporting limits, a rerun verification is requested. Persistent contamination results in repeating the QA procedure, noting sporadic issues on the certificate of analysis, or meeting with Support Services to determine corrective actions, which may include returning unacceptable materials to the vendor.

This government procurement document outlines Year 1 requirements for pre-filled chemical vial solutions, managed by Contracting Officer's Representative (COR) Douglas L. Mynard. The solicitation specifies estimated annual quantities for three distinct items packaged in cases of 24. Specifically, the procurement seeks 900 cases of 2.0 mL Ultrex-grade nitric acid solution (7.5-7.7N), 1,300 cases of 1 mL Trace Metal grade sulfuric acid solution (4.5N), and 200 cases of 2 mL Omni Trace hydrochloric acid solution (6N). All specified chemical solutions must be pre-filled into 4.5 mL polypropylene copolymer screw cap polyvials, referencing EP Scientific products or approved equivalents.
