The Indian Health Service’s Shiprock Service Unit is conducting market research via a sources-sought notice to identify contractors capable of laboratory testing and analysis of processing-quality water used in medical device processing. The work supports verification that utility water, critical water, and steam/steam condensate meet ANSI/AAMI ST108:2023 water-quality requirements. IHS will prioritize responses from Indian-owned Economic Enterprises (IEE/ISBEE) under the Buy Indian Act before considering other small-business set-aside programs, though other capable firms may respond. The applicable NAICS code is 221310 (Water Supply and Irrigation Systems) with a $41.0 million small-business size standard. Interested parties should email a company profile, capability statement, and, for IEE/ISBEEs, the IHS IEE Representation Form to Bertina Jones at bertina.jones@ihs.gov; this is not a solicitation and participation is voluntary market research.
