Research Racks Up Recognition Points for POU/POE   Water Quality Products June 2003   Wendi Hope King
Some really important research going on right now, which is critical for the point-of-use/point-of-entry (POU/POE) industry in order for POU/POE treatment to become an accepted practice for small public water system compliance. It seems as though we are closer than ever to finding acceptance in this arena.

A wide range of technologies, some new and some more traditional, is being marketed and applied for arsenic treatment. Each of these technologies has specific properties impacting its suitability for any particular scale of application. While rare, the ability of a single water treatment technology to perform effectively across many treatment platforms is not unique.

Manganese greensand is a specially processed medium for iron, manganese, and hydrogen sulphide removal. This premium non-proprietary filter medium is processed from glauconitic greensand on which a shiny, hard finite thickness manganese oxide coating is formed and is firmly attached on every grain by a controlled process.

Arsenic Treatment Options for the Southwest   Water Quality Products February 2003   Arizona Water Quality Association
While high concentrations of arsenic are found mostly in the Western region of the United States, parts of the Midwest and New England show levels of arsenic that exceed the newly approved U.S. Environmental Protection Agency (EPA) standard of 10 parts per billion (ppb). Individuals not willing to wait for their water system's compliance with the arsenic standard currently are looking for treatment systems to use in their homes. POU and even point-of-entry (POE) treatment systems are an attractive solution for these individuals. The process should begin with a basic understanding of arsenic contamination and the element's chemistry, a complete water quality analysis of the application-specific water and the knowledge of available technologies.

Arsenic Overview Series - Part 1   WaterInfoCenter January-December 2003   Sherry Odom
Arsenic is a naturally occurring metal found in rocks and soil, which can be released into the environment through geological events such as volcanic activity and erosion. Other releases of arsenic into the environment occur through industrial processes such as production of paints, metals, soaps, dyes, drugs, semi-conductors and wood preservatives, as well as in mining and smelting.

Arsenic Overview Series - Part 2   WaterInfoCenter January-December 2003   Sherry Odom
Consumers unwilling to drink arsenic contaminated water are demanding a more rapid implementation. Publicly owned utilities, however, will be held hostage from implementing a more rapid solution due to government approval cycles, annual budgets, required biding processes and slow implementation schedules. As a result, in-home treatment systems, which immediately can be installed, are a very popular treatment option for individual homeowners. Other advantages such as low implementation/operating costs and improved flexibility make the POU/POE approach option appealing.

In addition to officially sponsored research projects being performed throughout the world (see Section V for more information on research), many universities, government organizations and industry professionals are active in providing solutions to this issue. The following papers have been presented on arsenic treatment, health effects or policy issues at various tradeshows and conferences throughout the United States.

Arsenic Overview Series - Part 5   WaterInfoCenter January-December 2003   Sherry Odom
Research on arsenic can be broken down into three general areas -- health effects, treatment options and cost evaluations.There are more than 1,000 published research papers on health effects alone. This section provides an over-view of the most prominent research related to these areas which have impacted EPA’s decisions. There also are links to research organizations that can provide access to the specific projects conducted.

Arsenic Overview Series - Part 6   WaterInfoCenter January-December 2003   Sherry Odom
What research is being done at University's throughout the US? Colleges and universities across the U.S. are continuing their efforts in educating the population on the subject of arsenic. Both public and private universities are contributing their time, money, and expertise in areas of arsenic research such as geochemistry, health effects, and treatment options. Research programs, such as the ones listed below, are just a glimpse of the ongoing studies for arsenic. Ongoing research is necessary in order to continue to develop efficient and cost-effective solutions for the far-reaching problem of arsenic contamination.

Editor’s Note: Part 1 of this series provided a timeline for the development of a drinking water standard for arsenic. It also summarized the political and public reactions to the U.S. EPA decision to delay and withdraw the arsenic rule. Part 2 dealt with human exposure and advances in knowledge concerning human health effects of exposure to arsenic. Part 3 summarized early data on the occurrence of arsenic in U.S. waters.

Arsenic in Drinking Water - Part 3   Water Engineering & Management May 2002   John T. O’Connor, EngD, P.E.
Only recently has a substantial amount of data become available on the concentrations of arsenic in United States drinking water supplies. Most of these data have been accumulated by the state regulatory agencies responsible for monitoring drinking waters. Since the arsenic standard has been 50 µg/L, some state agencies have recorded arsenic concentrations only in excess of that concentration. Others have been limited by the sensitivity of the analytical techniques and equipment used for the arsenic analysis. As a result, much of the available arsenic data are “below the limits of detection.

Using Advanced Adsorptive Media for Arsenic Treatment   Water Engineering & Management April 2002   Greg Gilles and Jennifer Mathis
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.

POU Technology Demonstrates Effectiveness   Water Quality Products March 2002   By Jennifer Mathis, Apyron Technologies, Inc.
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.

Arsenic in Drinking Water - Part 2   Water Engineering & Management March 2002   John T. O’Connor, EngD, P.E.
On-going health effects studies and research reports (2001) appear to support the argument for lowering the current EPA drinking water standard for arsenic. Studies conducted by EPA, the University of North Carolina and the University of British Columbia have indicated that methylated metabolites of trivalent arsenic are genotoxic. In other words, they damage DNA in human cells.

The National Academy of Sciences, National Research Council (NAS-NRC) report was released on September 11, 2001. It concluded that the existing health effects data on arsenic essentially were sound. In addition, their review of three new epidemiological studies indicated that the health risks posed by arsenic in drinking water were greater than previously believed. As a result, in October, well before its self-imposed deadline, EPA rescinded its March implementation ban and endorsed the 10 µg/L arsenic MCL.

After the U.S. Environmental Protection Agency (EPA) finally announced the new maximum contaminant level (MCL) of 10 parts per billion (ppb) for arsenic, an estimated 4,000 community water systems are now left to take measures to lower their arsenic levels, which were previously at 50 ppb.

POU Options for Arsenic   Water Quality Products November 2001
The topic of arsenic has received a lot of press coverage this year, ever since the Bush administration halted the EPA’s newly issued maximum contaminant level (MCL) of 10 parts per billion (ppb). Since then, the MCL was reinstated back to 50 ppb and further discussions and studies have continued. This article will discuss some of these updates.
