Water QualityCheck™ Program

Proactively assess water quality at your facility

Do you assume the water in your facility meets the appropriate standards for drinking water? In turn, do visitors to your facility assume the water they drink is of acceptable quality? Are those safe assumptions? Gain added confidence with UL's Water QualityCheck™ program.

The Water Quality Gap

Water distributed by a municipal system is not regulated for most contaminants regulated under the Safe Drinking Water Act between the service line to a building and the tap and the quality of that water becomes the responsibility of the property owner.

You owe it to yourself to take reasonable steps to periodically monitor the quality of that water and to review the water systems in your building. You want safe, good tasting water for everyone. UL can help you do just that.

Water Quality Issues in Buildings

Unique characteristics of water systems in buildings may magnify public health risks. Water quality issues in buildings can arise from:

  • Extreme temperatures
  • Little or no disinfection residual
  • Areas of stagnation
  • Cross connections or backflow events

Current maintenance practices may not be sufficient to prevent waterborne infection and illness and a problem may only be discovered after a public health problem occurs.

Program Benefits

UL's Water QualityCheck program is specifically designed to address these issues by helping you:

  • Proactively identify and assess risks associated with drinking water quality
  • Leverage UL's expertise in water quality and quality management systems
  • Communicate your commitment to providing high quality water

How UL's Water QualityCheck program works

  • Step 1: Online survey - designed to establish the specific program scope for your facility
  • Step 2: Survey review conference call - initial team introductions, information gap assessment, audit plan development
  • Step 3: Onsite initial quality assurance audit - review of your facility's water system and sample collection
  • Step 4: Presentation and review of analytical results and audit findings
  • Step 5: Routine follow-up to assess ongoing compliance

Facilities that comply with UL's Water QualityCheck program will be authorized to display a certificate of compliance with UL's Water QualityCheck program. UL will also work with your facility to promote this accomplishment with your employees, customers and accreditors.
