As the residential point-of-use (POU) reverse osmosis (RO) industry approaches its 35th anniversary, it is time for a reality check on the industry's progress to date as well as a look ahead to new technologies or improvements that the industry may introduce for POU RO systems in 2003.
Looking for Answers in 2003 and Beyond
The Center for Public Health Education, a division of NSF International (www.nsf.org), The Public Health and Safety Company announces a conference on "Public Water System Compliance Using Point-of-Use (POU) and Point-of-Entry (POE) Treatment Technologies." NSF is a global provider of public health and safety-based risk management solutions.
Chlorine dioxide is not a new technology for public drinking water facilities or pulp and paper producers, but its use as a secondary treatment system for small-scale applications is new. Beyond the chemistry and microbiology, potential small-scale operators want answers to a few simple questions: Should I use it? How does it work? What extra work is it going to make for me?
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.
While both sides of the bottled/tap battle continue trying to inform and ultimately win the consumer over, a few facts cannot be overlooked. Regardless of how a consumer obtains drinking water, both bottled and tap must draw from the same available global freshwater sources. Despite the information with which consumers are presented, ultimately the decision is theirs. When purchasing bottled water, knowing what you are getting requires some research and understanding.
Glade Valley Nursing and Rehabilitation Center, Marriott Hotels, Starbucks and The White House may be vastly different with regard to the people who use and manage the facilities; yet when it was time to solve water quality problems, they all looked to the same resource: Kevin Britton, a RainSoft dealer at Quality Water of Maryland, located in Frederick, Md. (part of the Washington D.C. metro area).

The future of safe drinking water lies squarely in the hands of the point-of-use (POU) water purification industry. Growing awareness among decision-makers and consumers is the force behind the increasing importance of the POU industry.
On November 26, 2001, the new arsenic standard was signed into law—lowering the acceptable level for the contaminant from 50 parts per billion (ppb) to 10 ppb. Approximately 4,100 municipal water systems serving nearly 13 million people nationwide are affected by the law and are required to meet compliance by January 2006. According to the U.S. Environmental Protection Agency (EPA), 97 percent of these systems are small systems serving fewer than 10,000 people each. The economic impact on these small systems is likely to be large. However, there currently are options available to small municipalities that may be more affordable than central treatment.
New POU Technologies May Be the Answer for Small Municipalities Facing High Costs
In March 2001, the U.S. Environmental Protection Agency (EPA) withdrew a proposal for a lower maximum contaminant level (MCL) for arsenic in drinking water that would bring the standard from 50 parts per billion (ppb) to 10 ppb. At that time, the EPA commissioned three studies to examine the benefits, costs and health effects associated with a lower standard for arsenic.

Commercial point-of-use (POU) drinking water equipment and services is rapidly evolving into a multimillion dollar market. This growth can be attributed to several important trends.
