The VA Southern Nevada Healthcare System requires replacement of reverse osmosis carbon filter tanks with new Catalytic Carbon Filter Tanks for its Hemodialysis Clinic and Sterile Processing Service. Failure of water quality testing could cause facility-wide impacts, including inability to treat patients. Weekly disinfection and water sample testing by Marvel Water LLC is required to maintain ANSI/AAMI ST108:2023 standards, and adjustments by other vendors could disrupt this schedule. Responses must be submitted to Dennis Fennelly by July 1, 2026, at 4:00 PM Pacific Time, with documentation demonstrating capability to perform the requirement. The government will use responses to determine whether to conduct a competitive procurement instead of a sole source contract.
