FOUNTAIN VALLEY, Calif.--(BUSINESS WIRE)--June 17, 2003-- The Groundwater Replenishment (GWR) System, a new water project for Orange County, received the "2003 Drought Proofing Award" from the Santa Ana Watershed Project Authority (SAWPA).

Presented at the inaugural State of the Santa Ana Watershed Conference, the GWR System was honored for engaging in the most significant activity over the past year to assist in "drought proofing" the Santa Ana Watershed.

The Santa Ana Watershed Project Authority is composed of five member water agencies totaling 2,650 square miles in Southern California: Eastern Municipal Water District, Inland Empire Utilities Agency, Orange County Water District, San Bernardino Valley Municipal Water District and Western Municipal Water District. SAWPA's mission is to plan and build facilities to protect the water quality of the Santa Ana River Watershed.

"The Groundwater Replenishment System is one of the major projects in the Santa Ana Integrated Watershed Program (IWP) that will assist in drought proofing the region," commented Joe Grindstaff, general manager of SAWPA.

"This is a 10 year, $3 billion program that will drought proof the watershed by creating over 1 million acres of new water supply and over 10,000 acres of new wetlands and open space. The GWR System is the largest single source of new water supply in the IWP and we felt it was appropriate that this project receive the first annual Santa Ana Watershed Drought Proofing Award," said Grindstaff.

The GWR System is a joint project of the Orange County Water District and Orange County Sanitation District. The project will produce water similar in quality to bottled water, by taking highly treated sewer water that is currently released into the ocean, and purifying it through microfiltration, reverse osmosis and ultraviolet light with hydrogen peroxide advanced oxidation treatment.

The purified water will become part of a seawater barrier and be pumped through a 13-mile pipeline to percolation ponds in Anaheim where it will seep into deep aquifers and blend with Orange County's other sources of groundwater, following the same natural filtering path rainwater takes through the ground.

"One of the exciting aspects of the GWR System is regardless of rainfall or drought, purified water will be available. This is truly a new water supply for Orange County," said Denis Bilodeau, president of the Orange County Water District.

Once completed in 2007, the GWR System will produce 72,000 acre-feet (or 23.4 billion gallons) of purified water annually -- enough water to serve 140,000 Orange County families.

"The GWR System is a model for other wastewater and water agencies to follow," said Blake Anderson, general manager of the Orange County Sanitation District.

The project will help meet future predicted water shortages in Orange County. It will also help reduce the mineral content of Orange County's groundwater and prevent ocean water from contaminating the large groundwater basin. Additionally, it will provide water during droughts, a reoccurring event in Southern California.

Atlanta, GA. - Adedge Technologies, Inc, a leading supplier of specialty adsorbent products and systems for arsenic removal from water and wastewater applications, and the United States Environmental Protection Agency (EPA) have announced that Adedge has been awarded three full-scale demonstration sites for its arsenic removal technology for municipal drinking water systems. The locations are Nambe Pueblo, NM, Rimrock, AZ and Rollinsford, NH .

The Environmental Protection Agency (EPA) estimates that approximately 13 million people in the U.S. alone routinely drink water containing arsenic at concentrations greater than allowed under recently established government standards. The EPA's new Arsenic Rule requires treatment for all public drinking water systems with arsenic levels greater than 10 parts per billion (ppb), by January 2006. This represents a dramatic decrease from the current standard of 50 ppb. Small public water systems serving less than 10,000 people will be financially impacted most from the new arsenic rule. The EPA demonstration program is an aggressive program to further qualify commercially-ready technologies that result in significant cost savings over previous technologies.

Adedge Technologies relies on a patented granular ferric oxide technology developed by Bayer and marketed as Bayoxide E-33 to reduce arsenic contamination in small municipal and industrial applications. The technology has been commercially proven to effectively and economically meet new government standards. This media which has NSF 61 approval is an integral component in AdEdge's line of AD-33 arsenic removal systems and products for small community and non-community drinking water systems. Additionally, AdEdge is uniquely applying this technology into the point-of-use and point-of-entry residential marketplace.

"This technology has quickly earned a terrific reputation within the industry as the most cost effective and simplest way to remove arsenic from the drinking water. The ability to participate with the EPA to demonstrate these advantages further benefits small community water systems who have been very concerned about the high costs associated with earlier technologies and want low cost, simple solutions," states Rich Cavagnaro, President.

About Adedge Technologies

Adedge Technologies ( www.adedgetechnologies.com ), based in Atlanta, Ga., is an innovative distribution, marketing and technical services company supplying specialty adsorbents, integrated systems and other products for the removal of contaminants from process or aqueous streams within drinking water, environmental remediation, chemical, wastewater and pharmaceutical applications.

WATERBURY, CT -- Continuing its tradition of innovation, Haestad Methods announced the release of PumpMaster, a revolutionary new pump selection and analysis tool that dramatically streamlines the process of selecting and designing the most efficient pump solutions. Haestad Methods, the world's leading provider of water resources management software, showcased PumpMaster this week in Anaheim, California, at the 2003 AWWA Annual Conference.

PumpMaster contains a high-performance search engine and a database of thousands of pump performance curves from top pump manufacturers, making it the industry's most comprehensive and up-to-date source for pump information. Knowing only the flow and head required, PumpMaster's highly intuitive interface guides the user through a search of performance curves and automatically returns a list of the best selection of pumps in seconds.

"PumpMaster offers a unique alternative to traditional pump catalogs and single-manufacturer pump selection software," said Diego Diaz, Haestad Methods' project manager for PumpMaster. "It allows Haestad Methods' existing clients as well as fluid flow analysis professionals to instantaneously find, select, and analyze best-fit pumps more easily, efficiently, and accurately."

Available as either a stand-alone application or an Internet-based service ( www.pumpmaster.com ), PumpMaster promises to increase pump buying confidence for engineers and operators in the water and wastewater, mechanical, industrial, process manufacturing, and petroleum industries. System head curves from Haestad Methods' modeling products can also be directly used in PumpMaster to support the pump selection process.

"After an in-depth evaluation, I found PumpMaster can speed up the pump selection process which would save a significant amount of valuable time," said Lindle Willnow, P.E. Project Manager and Technical Specialist for Metcalf & Eddy. "With PumpMaster's advanced capabilities, I can quickly select the most suitable pump from a wide range of manufacturers and, if I want, incorporate it directly into my WaterGEMS hydraulic model."

Hi Everyone,

Being the owner of Water and Wastewater.com, I have been inundated with SPAM emails this year, you know the ones that promise: money, better sex life, home loans, etc.  Since April I have been testing some different software packages for what I call "Spam Interception".  I prefer this method rather than having my emails blindly discarded without review.

My recommendation is a software package which works with most email programs, including Outlook and Outlook Express.  Spam Killer 4.0 by McAfee has both preset filters plus free filter update service online, but most importantly allows you to quickly add filters based on keywords, domains, return email address, and more.  "Out of the box" it cut my 500-700 Spam emails per day by 50-70% and with a little tweaking it is removing about 90% of incoming Spam.

Most importantly, the software goes through my email files and automatically adds people I correspond with to its "friends" list.  It is a very flexible package.  You can buy SpamKiller directly from Amazon.com for about $20 and it is worth every penny.

Mr. Fein needs quick testing method:

We are looking for some quick and dirty screening tests to monitor and troubleshoot effluent from a meat rendering plant effluent for levels of FOG, TSS and blood. We are trying to track down cause of high material loadings to the sewer and would like something semi-analytical rather than a subjective visual characterization.

I also need something much faster than having to run TSS, COD, etc., because of the large number of samples. We have tried (with limited success) centrifugation, centrifugation of acidified effluent, centrifugation following solvent addition, measurement of light absorbance, total dry wt. and measurement of turbidity.

I am considering trying a hand held refractometer but don't really think this will do to well. Any suggestions based on your experience would be appreciated.

Mr. Keenan needs help tank corrosion:

A glass-lined steel tank, (approximately 1,100 m3 capacity, with TWL at about 5 m), was installed as part of a wastewater treatment plant at an abattoir in July 2002. The tank is fitted with a submerged aeration system using stainless steel piping.

In recent weeks the tank was observed to have a leak in one of the glass lined panels. This leak appeared as a small hole located away from any joining in the panels. Initially it was thought that the particular panel may have been damaged during installation, but when the tank was emptied it was found to contain several hundred locations where attack of the tank fabric was clearly evident, in the form of "pitting" of the metal in the panel.

Has anyone come across this problem before, and would the installation of a sacrificial anode, (possibly zinc), in the tank cure the problem, or would the complete insulation of all possible connections between the stainless steel pipe work and the walls and floor of the tank be a possible solution?
