NSF International — founded by University of Michigan public health faculty during the polio pandemic of the 1950’s — has since grown to be one of the first names in standard setting for public health; drinking water safety high among its priorities.
NSF International continuously maintains its consensus products on a continuous maintenance basis. NSF 53 Drinking Water Treatment Units is one of several related water safety titles in its bibliography:
It is the purpose of this Standard to establish minimum requirements for materials, design and construction, and performance of point-of-use and point-of-entry drinking-water treatment systems that are designed to reduce specific health-related contaminants in public or private water supplies. Such systems include point-of-entry drinking-water treatment systems used to treat all or part of the water at the inlet to a residential facility or a bottled water production facility, and includes the material and components used in these systems. This Standard also specifies the minimum product literature and labeling information that a manufacturer shall supply to authorized representatives and system owners, as well as the minimum service-related obligations that the manufacturer shall extend to system owners.
In last week’s ANSI Standards Action NSF International posted changes to NSF 53 Drinking Water Treatment Units; available at the link below:
The proposed change remedies the lack of requirements for conditioning and conditioning volumes in the presence of microcystin; a type of toxin produced by freshwater blue-green algae.
Comments are due August 2nd.
Because NSF International posts its redlines in ANSI standards action, and also on NSF Online Workspace; it is easier respond to calls for public comment. This facility is especially important in the public safety domain.
You may communicate directly with the NSF Joint Committee Chairperson, Mr. Tom Vyles (email@example.com) about arranging direct access as an observer or technical committee member. Almost all ANSI accredited technical committees have a shortage of user-interests (compliance officers, manufacturers and installers usually dominate).

We encourage front line staff with experience, data and war stories to participate by communicating with Tom Vyles. We also host a periodic teleconference on the topic of the twenty-odd water safety and sustainability consensus products that affect #TotalCostofOwnership of education communities. See our CALENDAR for the next Water and Sport teleconferences; open to everyone.
As cities-within-cities many colleges and universities own and maintain at least 10 miles — and possibly up to 1000 miles — of underground piping for water, steam and natural gas; much of it under pressure within buildings or in outside, underground tunnels. The American Society of Mechanical Engineers develops a suite of standards for these, and many other piping systems:
Health Level Seven International (HL7), founded in Ann Arbor, Michigan in 1987, is a not-for-profit, ANSI-accredited standards developing organization dedicated to providing a comprehensive framework and related standards for the exchange, integration, sharing, and retrieval of electronic health information that supports clinical practice and the management, delivery and evaluation of health services. HL7 is supported by more than 1,600 members from over 50 countries, including 500+ corporate members representing healthcare providers, government stakeholders, payers, pharmaceutical companies, vendors/suppliers, and consulting firms.
HL7 runs an outstanding content management system for its best practice titles linked below:
Like many consensus product developers with a continuous maintenance process, it has developed its own proprietary user interface.
Today we include HL7 in our monthly scan of ANSI-accredited standards under continuous maintenance. One of its parent standards, described below, is open for public review:
HL7 V2 Conformance. The intent of the project is to update the conformance methodology used to profile message definitions and to separate (divorce) the conformance chapter (currently Chapter 2B) from the ‘main’ HL7 v2 standard.
– Provide an independent (separate) HL7 v2 Conformance Methodology standard.
– Update the conformance constructs and profiling mechanisms used for implementation guide creation
– Update the profile schema that supports the XML computable representation for implementation guides and message profiles
– Deprecate by means of an errata the Conformance chapter/section from all prior V2 versions. (our expectation is that the content of conformance testing of existing IGs will not change, but going forward any new specification will use this updated conformance methodology). To be clear, the proposal is an updated method of how to specify conformance for new IGs.
– Identify opportunities to encourage adoption by external implementation guide developers (e.g., IHE) to use the same conformance definitions and constructs.
Comments due July 27th.

We maintain the HL7 suite on the standing agenda of our Health and Nota Bene teleconferences. See our CALENDAR for the next online meeting; open to everyone.
