The NSF drinking water treatment unit testing and certification program includes standards to address the wide variety of point-of-use (POU) and point-of-entry (POE) drinking water treatment technologies on the market today, with more than 3,000 systems and 2,000 components currently certified under seven NSF/ANSI standards. These seven technology-specific standards are listed in Table 1.

The point-of-entry (POE) market for ultrafiltration (UF) membrane systems has grown considerably in recent years. Respected market researchers Frost & Sullivan had predicted that the market for hollow fiber UF membranes would increase at a compounded annual growth rate of 12.9% from 2004 to 2010, though there are signs that the actual growth rate during the latter part of this period may be above original estimates.

This past October marked the 35th anniversary of the U.S. Environmental Protection Agency’s (EPA) Clean Water Act. This legislation certainly changed the landscape for national water quality issues by establishing a basic structure for regulating discharges of pollutants into U.S. waters and giving the EPA authority to implement pollution control programs. The act also continued requirements to set water quality standards for all contaminants in surface waters.
