F103--Utility Critical Water Testing at Asheville VAMC

B.3 PERFORMANCE WORK SCHEDULE 1. Scope of Work a. The scope of this work is all labor and materials to provide testing and reporting services per ANSI/AAMI ST108: 2023 for utility and critical water systems. The goal is for the successful bidder to test the critical water system to prove compliance with Table 1: Type of Water Utility Water(1) Critical Water Water Use Units Flushing/Washing/Rinsing Final Rinse(2)/ Steam pH(4) pH 6.5 – 9.5 5.0 – 7.5 Conductivity (mg/L = ppm) µS/cm < 500 < 10 Total Alkalinity mg CaCO3 /L < 400 <8 Total Hardness mg CaCO3 /L < 150(3) < 1 Bacteria CFU/mL < 500 < 10 < 10 Endotoxin EU/mL N/A < 10 < 10 Total Organic Carbon (TOC) mg/L N/A N/A < 1.0 Color and Turbidity Visual Colorless, clear, without sediment Colorless, clear, without sediment Colorless, clear, without sediment NOTE 1: This is the quality of water that might come from the tap but might need some form of treatment to achieve these specifications. NOTE 2: If this is the final rinse prior to sterilization of a critical device. NOTE 3: If hardness is greater than 150 mg/L, a water softener is recommended unless used for washing and the cleaning chemistry is capable of handling higher levels of hardness. NOTE 4: For boiler-treated steam, most boilers are treated to maintain a pH of 7.5 or 9.2. Any treatment of water that goes into boilers should be in accordance with the sterilizer and boiler manufacturers’ written IFU. Table 1: Categories and recommended levels of water quality for medical device reprocessing. 2. Location of Work a. Testing services shall occur at the Sterile Processing Service department, located in the basement of Building 47 at 1100 Tunnel Road, Asheville, NC, 28803. 3. Testing Testing shall be provided within the Table 2 schedule below: Characteristic Type of testing Sample site Samples taken and analyzed by Suggested frequency of testing CGVAMC Responsible Service Bacteria Heterotrophic plate count (1) Reprocessing area at each of the 11 point-of-use sites (3 - critical sinks, 1 - utility sink, 1 - RO storage tank, 4 - medivator sterilizers, 2 – washers). Immediately downstream of water treatment process. Contractor Weekly FMS (contract) Endotoxins LAL test Reprocessing area at each of the 11 point-of-use sites (3 - critical sinks, 1 - utility sink, 1 - RO storage tank, 4 - medivator sterilizers, 2 – washers). Immediately downstream of water treatment process. Contractor Monthly FMS (contract) pH pH meter Reprocessing area at each of the 11 point-of-use sites (3 - critical sinks, 1 - utility sink, 1 - RO storage tank, 4 - medivator sterilizers, 2 – washers). Immediately downstream of water treatment process. Contractor Monthly FMS (contract) Total hardness Determination of ppm CaCO3 by handheld meter, titration kit, or colorimetric dipsticks. Reprocessing area at each of the 11 point-of-use sites (3 - critical sinks, 1 - utility sink, 1 - RO storage tank, 4 - medivator sterilizers, 2 – washers). Immediately downstream of water treatment process. Contractor Monthly FMS (contract) Conductivity Conductivity Meter Reprocessing area at each of the 11 point-of-use sites (3 - critical sinks, 1 - utility sink, 1 - RO storage tank, 4 - medivator sterilizers, 2 – washers). Immediately downstream of water treatment process. Contractor Monthly FMS (contract) Total Alkalinity Alkalinity test kit Reprocessing area at each of the 11 point-of-use sites (3 - critical sinks, 1 - utility sink, 1 - RO storage tank, 4 - medivator sterilizers, 2 – washers). Immediately downstream of water treatment process. Contractor Monthly FMS (contract) Ionic contaminants Specific tests for aluminum, chloride, copper, iron, manganese, Nitrate, Phosphate, Sulfate, Silicate, Zinc. The main water feedline into the facility Contractor Annually FMS (contract) NOTE 1: The specifications presented in this table should be tested to the parameters specified in Table 1 and in accordance to ANSI/AAMI ST108: 2023 where applicable. NOTE 2: The recommendations for frequency of testing in this table are the recommended minimum frequency. If problems or issues arise with the water quality, it might be necessary to increase the frequency until they are resolved. Table 2: Overview of water quality monitoring, edited to include Responsible Party. b. The successful bidder shall provide testing services for critical water (reverse osmosis) for bacteria (weekly), endotoxin (monthly), pH (meter) (monthly), total hardness (monthly), conductivity (monthly), total alkalinity (monthly), and ionic contaminants (annually) per Table 2 above. c. Tests shall occur at the required locations per Table 2. The ‘main water feedline into the facility’ shall be tested at the domestic water supply inlet to the critical water system. d. Water sampling shall be performed in accordance with ANSI/AAMI ST108:2023 Annex H. 4. Testing Days a. Testing shall occur during normal business hours (8AM – 4:30PM). b. Testing shall occur between the 10th and 15th day of the month. c. The successful bidder shall notify the Contracting Officer’s Representative (COR) prior to travelling to the site to ensure that testing can be completed on the requested date. The COR may request to move the testing date due to mission requirements and this shall result in no additional cost to the government to reschedule. 5. Reporting a. Reporting shall be per typical company reporting documentation. Additionally, documentation shall be reported per Attachment A (excel sheet). b. Reports shall be provided through email to the COR before the last business day in the testing month. c. Reports shall provide recommendations for remediation of deficient testing parameters. d.
