Avoiding liability through development of standards and certification programs
"Filtered, bottled or on the rocks with a swizzle and a lime. However you prefer your water, we certify it.” goes the copy of a current NSF advertisement. The NSF International certification programs are certainly well known in all aspects of the water industry—treatment, additives, plumbing, contact surfaces and, of course, bottled water.

A reputable laboratory should be able to help you determine what type of laboratory certification is required, if any, for the specific sample testing you are looking to have performed. Laboratories will typically provide all the sampling containers and collection instructions to ensure the accuracy of the sampling.
Whatever the structure of the testing service provider, the manufacturer must be satisfied that their partner can deliver the project turnaround, quality, scope of services, reliability, and ultimately, the value that they need.
Technology-specific testing methods in relation to the American National Standards
This article summarizes the current state of efforts to address this hot topic from the point of view of the NSF/ANSI Drinking Water Treatment Unit (DWTU) Standards.

In February, NSF International arranged for many experts to cover the issues and facets of point-of-use and point-of-entry (POU/POE), how they can be used for PWS compliance and other opportunities for the manufacturers and users. This article is intended to provide opinions and a broad conference overview.
A study published as part of the EPA's Environmental Technology Verification (ETV) Program verifies the performance of a Fyne Process membrane filtration plant tested on high organic-laden surface water in Barrow, Ark. The plant was able to remove significant levels of organics--precursors to disinfection byproducts such as trihalomethanes (THM) and haloacetic acids (HAA)--producing water that easily met the disinfection byproduct standards set by the EPA's stringent Stage 1 D/DBP Rule.
Faucets for point-of-use (POU) water treatment systems must combine an attractive, contemporary appearance with materials that ensure safety and purity. POU faucets and systems are becoming increasingly important to help meet consumer demands for safe, high-quality drinking water. It is estimated that by 2020 almost every household will have a POU or point-of-entry (POE) water treatment system.
