DENVER, CO -- The August 2004 issue of Journal AWWA marks the 90th anniversary of the American Water Works Association’s flagship publication.

“The best minds in the water community have shared their experience and professional insights through the pages of Journal AWWA for 90 years,” said Jack Hoffbuhr, AWWA’s executive director. “Together they’ve told a remarkable story of commitment to safe drinking water – a story that continues to unfold today. In the coming decades, the new ideas, and shared wisdom from each issue will continue to inform and inspire new generations of water professionals dedicated to protecting public health.”

Both a professional and a scholarly publication, Journal AWWA began publication in 1914 as a quarterly with a circulation of 1,200. Today with a circulation of over 46,000, the Journal offers timely, technically accurate, peer-reviewed information about water quality, resources, and supply and about the management and operation of water utilities. With a pass-along readership of over 90,000, the Journal reaches a diverse, worldwide readership each month.

“I began receiving the Journal in 1977, when I started my very first job in the drinking water profession,” said David Leland, Drinking Water Program manager with the Oregon Department of Human Services. “Journal AWWA has always been, and continues to be, my number-one source of current information on drinking water issues and technology.”

From a landmark article advancing the ammonia-chlorine process of disinfection in 1916, to a primer on the basics of counterterrorism in May 2001, Journal AWWA has a long history of staying on the cutting edge of the water industry. Through the years, the Journal has tackled issues such as waterborne diseases in the 1930s, disinfection by-products of chlorination in the 1970s, and regulatory compliance and security today. Additionally, the Journal has responded to changes and needs of the industry, launching e-Journal AWWA in 2002 and addressing issues in new columns such as Committee Connection, Market Outlook, and Workforce Diversity.

AWWA is the authoritative resource for knowledge, information, and advocacy to improve the quality and supply of drinking water in North America and beyond. AWWA is the largest organization of water professionals in the world. AWWA advances public health, safety and welfare by uniting the efforts of the full spectrum of the drinking water community. Through our collective strength we become better stewards of water for the greatest good of the people and the environment.

Watershed Management : 'Bacterial Fingerprinting' Offers New Technology

WESTFORD, MA -- Millions of dollars are spent each year to combat bacterial contamination of water supplies, recreational waters, and shellfisheries in the U.S. ENSR International's Research and Development (R&D) Program and the University of Massachusetts/ Boston (UMass) are working together to solve this problem by demonstrating the use of "bacterial fingerprinting" technology on water samples from the Souhegan River in southern New Hampshire.

Using high resolution DNA "fingerprints", scientists will map profiles of various strains of E. coli bacteria to identify its specific sources of origin. For example, bacteria from humans (e.g., septic failures, illicit storm sewer hook-ups) can be differentiated from that of farm animals or wild animal populations.

ENSR water resource manager Dr. Kenneth Wagner explains, "Scientists and environmental agencies will be able to identify and target specific sources of water pollution, according to the bacterial "fingerprints" left at the scene. This new technology has enormous potential to improve the effectiveness and efficiency of clean up efforts for water bodies."

ENSR and UMass scientists are now taking a second set of samples for DNA analysis of bacteria following a rainy period. The first samples were taken after a dry spell; the final round will follow an intense, short-duration storm. Recent E. coli test results along the Souhegan River are available at http://www.souhegan.org/souecoli04.html.

The Souhegan River, which runs through residential, rural, agricultural, industrial, and wilderness areas, was selected for its diverse study conditions. ENSR's R&D Program has sponsored more than 90 innovative projects over the past 15 years. For more information about these or other R&D projects, contact the Director of ENSR's R&D Program, Dr. Michael Mills at (800) 722-2440.

A full-service environmental firm, ENSR International (http://www.ensr.com/) provides air and water quality services to industrial and government agency clients from 70 worldwide offices. Founded in 1968, ENSR won Environmental Business Journal Achievement Awards in 2001, 2002, and 2003.

NEW YORK, NY -- Bion Environmental Technologies, Inc. and its subsidiary, Bion Dairy Corp., announced today the results from the study conducted at the Bion installation located on the 1,250 cow DeVries Dairy, in Dublin, TX.

The study was conducted from December 10, 2003 through July 15, 2004. Gas, liquid and solid samples were sent to independent laboratories utilizing testing protocols approved by a third-party scientific review panel, including independent pollution control experts from several land grant universities.

In summary, the study found that the Bion waste management system achieved the following results:

1. Phosphorus and Nitrogen removal rate of 79% and 74%, respectively, when
incorporating a centrifuge into the Bion waste management system for
separation of fine solids.
2. 95% conversion of soluble Phosphorus to particulate form.
3. Dramatically reduced emissions of air pollutants relative to baseline
dairy emissions (i.e. California Air Resources Board) as follows:
- Ammonia (NH3) - 99.5% to 99.9% reductions over the baseline.
- Non-Methane Organic Compounds (NMOC's) - 98% to 99.6%.
- Hydrogen Sulfide (H2S) - 94% to 98%.

The complete report, entitled "DeVries Dairy Bion NMS Nutrient and Atmospheric Emission Quantification Project Analytical Approach Details and Results" can be viewed on Bion's website at http://www.biontech.com/ or by requesting a copy from the Company.

Free Report

Also available on the website is a Bion paper entitled "Bion Technical Summary Performance Report: Implications for Public Policy," which contains a discussion of public policy implications and economic analysis of the Bion waste management system, as well as a summary of the technical data contained in the report.

With the ability to significantly and cost effectively reduce the pollution from dairies now regulated by the Clean Water Act and the Clean Air Act, Bion's proprietary technology provides a means for dairies to remain competitive while meeting environmental regulatory requirements.

About Bion

The Bion companies design and operate advanced waste and wastewater treatment systems for large dairy farms as well as swine and other animal facilities. Bion systems utilize patented biological and engineering processes to provide proven treatment solutions to the nutrient management and air emissions problems associated with these operations.

Mr. Serrano wants information on methanol acclimatization :

I have to support a team which is charged to carry on a study about denitrification by making use of methanol. In this study we have to obtain a table BCOD (methanol) related with the corresponding NUR.  The study should be made in the laboratory, by reproducing the anoxic phase of the plant, with an activated sludge that have never been mixed with methanol.

My questions are:  
 1. Can we start the study without taking care about any sludge acclimatization?
 2. Should the activated sludge be acclimated before we start the experiments?
 3. How could we acclimate the activated sludge to the methanol in our laboratory? Is there any procedure?
