Cold Water Canyon Water Company Selects ADSORBSIA™ Arsenic Removal Media from Dow for Use in Aquacell Water Treatment Systems in Black Canyon City, Arizona

Midland, MI - May 24, 2006

ADSORBSIA™ GTO™ arsenic removal media from The Dow Chemical Company, in conjunction with equipment provided by Aquacell Water Inc., (OTC:AQWT) has been selected by Cold Water Canyon Water Company for use in three water treatment systems serving Black Canyon City, Arizona. Cold Water Canyon Water Company serves half the population of Black Canyon City, roughly 1,700 people.

The use of ADSORBSIA will enable Cold Water Canyon Water Company to meet the new U.S. EPA arsenic standard for drinking water of 10 parts per billion (ppb). Arsenic levels are currently 17 ppb in two of the systems and 22 ppb in the other. The arsenic removal systems were installed in late April 2006.

“After consideration of several arsenic removal products, we are extremely satisfied with our selection of ADSORBSIA media from Dow to meet our arsenic removal needs in Black Canyon City,” said Roger Wagner, president of Cold Water Canyon Water Company. “It is important that we supply water to our customers that complies with the EPA standard, and we are confident that ADSORBSIA is the most reliable media choice for our water systems while minimizing the cost for meeting the regulation. The ability to combine this media choice with systems from a high-quality company like Aquacell made this an easy choice.”

As criteria for selection of an appropriate adsorption media option, Cold Water Canyon Company compared the benefits of ADSORBSIA™ titanium-based media over other adsorption media. Those benefits include a smaller system footprint, ease of operation, low cost of media, hassle-free disposal of spent media, and overall performance.

Of particular importance was the need for an arsenic removal product that was suitable for small to mid-sized systems. Two of the water treatment systems have flow capacities of 150 gallons per minute (gpm) and the other has a flow capacity of 50 gpm. Combined, the three systems deliver 326,000 gallons of water per day at peak operation.

“As more municipalities and drinking water systems work towards meeting the EPA arsenic standard, particularly in regions like the southwest United States where arsenic levels are naturally elevated, ADSORBSIA titanium-based media offers a trustworthy, and affordable option for small to mid-sized systems such as these,” said Alan Greenberg, senior marketing development manager, Dow Liquid Separations New Business Development. “We are very excited that Cold Water Canyon Company has selected ADSORBSIA media and Aquacell Water Inc. for this project.”

ADSORBSIA arsenic removal media is distributed in southwest U.S. through Aquacell Water Inc., a manufacturer of turn-key water treatment systems, and Dow-authorized distributor for ADSORBSIA™ GTO™ media since April 2006.

ADSORBSIA titanium-based media has improved performance and capabilities over iron oxide-based adsorbent media, including a nanocrystalline structure that leads to faster kinetics, allowing for smaller diameter vessels, faster flow rates and a smaller system footprint. It also has the highest capacity over a range of water conditions, and can thus be used effectively in existing system designs for removing both As (III) and As (V) without pretreatment, under all pH conditions.

The high capacity of ADSORBSIA makes it an ideal, non-regenerable single-use product, of particular convenience for small to mid-sized systems, offering an affordable, easy-to-operate approach. Eliminating the need for regeneration also prevents hassles and cost of chemical storage, and disposal of arsenic-laden waste regenerant streams. ADSORBIA media has a strong affinity for arsenic, which permits the media to maintain a stronger hold on the removed arsenic, thereby leading to easier and safer disposal.

ADSORBSIA™ media was launched by Dow Liquid Separations in 2005. It is designed to help municipalities comply with the new EPA standard, effective January 23, 2006, requiring drinking water in the United States to have arsenic levels below 10 ppb, a substantial reduction from the previous limit of 50 ppb.
