ANSI/AAMI ST108 Water Quality Standard Compliance Support
The ANSI/AAMI ST108 water quality standard sets evidence-based requirements for water used in medical device reprocessing. Replacing TIR34, it provides clear guidance on testing, monitoring, and documentation to ensure safe, consistent, and compliant sterilization practices. A-Tech Consulting helps hospitals, surgical centers, and SPDs achieve and maintain ST108 compliance with confidence.
A-Tech serves hospitals, surgical centers, and SPDs across California and the Pacific Northwest.
Why Water Quality Matters in Medical Device Reprocessing
Prevents deposits and corrosion that damage instruments and washers/sterilizers.
Reduces risk of healthcare-associated infections (HAIs) due to residual contaminants
Supports accreditation survey success (TJC, CMS, AAAHC) with proper documentation
Limits downtime, extends equipment life, and lowers long-term costs.
Key Requirements Under the ANSI/AAMI ST108 Standard
Water Classifications
Utility water – For flushing/cleaning; meet baseline chemical & physical parameters
Critical Water – Highly purified for final rinses to avoid residues and microbial growth
Steam – Clean, dry, non-contaminating steam for sterilizers to protect instruments
What Needs to Be Tested
• pH, condutivity, hardness/alkalinity
• Microbial counts and as applicable endotoxins
•Total Organic Carbon (TOC)
•Target ions/metals (e.g., chloride, iron, copper) based on system risk
Who Needs to Comply
♦ Hospitals & Health Systems
♦ Outpatient & Specialty Surgical Clinics
♦ Sterile Processing Departments (SPDs)
♦ Ambulatory Surgery Centers (ASCs)
♦ Dental & Oral Surgery Centers
