Dr. Elsa Murano, vice chancellor and dean of agriculture and life sciences for The Texas A&M University System, and John Stropp, interim president of the Texas A&M Foundation, look on.

Steve Clark, the developer of ZEROS, established the alliance to fund water and bio-energy research and education programs at The Texas A&M University System. The gift will honor Clark's long-time friend and business partner, William A. McKenzie, a former chairman of the Texas A&M University System Board of Regents.

"My relationship and friendship with Bill McKenzie and his encouragement in developing ZEROS and his push for tomorrow's solutions today has been a catalyst for this gift," Clark said.

Zero-Emission Energy Recycling Oxidation System, or ZEROS, is an oxy-fuel technology which uses high temperatures to completely oxidize organic waste. It was developed to clean up oil field waste without polluting air or water.

Currently, ZEROS is being commercialized to produce electrical energy, liquid fuels, pure carbon dioxide and distilled water with a complete sequestration of carbon dioxide and other contaminants.

Gray water alternative for sub-irrigating landscape plants

Dr. Bruce Lesikar, Texas Cooperative Extension agricultural engineer, said gray water is an alternative, and cheaper, source of water for landscaping in Texas.

Gray water is the water that has passed through showers, sinks, bathtubs or washing machines. It is different from black water that comes from the toilet or kitchen sink and often contains solids, therefore making it unusable without treatments.

"If you are planning on a gray-water system, you have to start by planning early," Lesikar said. "Houses that are on blocks or above the ground do have the ability to be re-plumbed to separate gray water for use. For houses that are on slabs, it is more difficult to separate the sources once the house is built."

Gray-water systems can be used on all soil types, and state regulations affect how the systems may be installed and used.

TWRI grant recipient studies water scarcity in Texas

Texas A&M University international graduate student Yongxia Cai is working with her advising professor Dr. Bruce McCarl from the Department of Agricultural Economics to develop an effective water model to evaluate the impact of interbasin water transfers in Texas.

Cai, originally from China and a recipient of a $5,000 2006-2007 Texas Water Resources Institute (TWRI) research grant, said that water scarcity is a problem in Texas because of rapid population growth, economic development, global warming and water pollution.

"To address the water scarcity problem, one of the water supply enhancement strategies is interbasin water transfer (IBT), shifting water from surplus to deficit regions," Cai said.

However, in Cai's final report she said water transfers can have negative impacts on the environment, and there is no comprehensive evaluation methodology proposed for them. The Texas water models have limitations that affect their usefulness in evaluating these transfers.

TWRI grant recipient developing 3-D model for Corpus Christi Bay

Texas A&M University international graduate student Mohammad Shahidul Islam is working with his advising professor Dr. James Bonner from the Zachry Department of Civil Engineering to develop the Coastal Margin Observation and Assessment System (CMOAS) to monitor water quality in the Corpus Christi Bay.

"The CMOAS is conceptualized as an environmental observatory that can supply surface current maps, vertical profiles of currents, meteorological observations and other real-time chemical and biological measurements within the water column," said Islam, who received a $5,000 2006-2007 Texas Water Resources Institute (TWRI) research grant.

Islam, originally from Bangladesh, found that in Corpus Christi Bay the water unexpectedly becomes stratified in the summer which causes hypoxia, a condition where the concentration of dissolved oxygen in water gets too low and aquatic life cannot survive. In his final report, Islam explained that the spatial extent, frequency and duration of hypoxia determine the level of disturbance it causes to the ecosystem. He also found that Corpus Christi Bay is a bi-directional system; wind forces move the water in one direction and tidal forces move the water in the opposite direction. Thus a three-dimensional model is necessary to accurately capture the dynamics of the bay.

New Publications/ Papers

"Watershed Protection Plan Development for the Pecos River" W. Belzer and C. Hart, TWRI publication TR-302 To identify potential salinity sources, it is necessary to locate and characterize potential impacts of perennial and intermittent tributaries into the Pecos River. A study to determine water quantity, quality and point of impacts from sources outside of the main stem was conducted in 2005. The first phase involved analyzing maps to determine potential tributary locations and to locate sampling points based on accessibility. The second phase was to acquire water and sediment samples, determine flow volume and submit samples for laboratory analysis. In the case of dry streambeds that could potentially carry water during storm events, sediment samples were collected for laboratory analysis. This report summarizes the sample collection efforts and analysis of data collected from tributaries.

"Economic and Financial Costs of Saving Water and Energy: Preliminary Analysis for Hidalgo County Irrigation District No. 2" A. Sturdivant, M. Rister and R. Lacewell, TWRI publication TR-303 Initial construction costs and net annual changes in operating and maintenance expenses are identified for a three-component capital renovation project proposed by Hidalgo County Irrigation District No. 2. The proposed project primarily consists of replacing aged mortar-joint pipe in pipeline units I-7A, I-18, and I-22 with new rubber-gasketed, reinforced concrete pipe. Both nominal and real estimates of water and energy savings and expected economic and financial costs of those savings are identified throughout the anticipated useful life for the proposed project. Sensitivity results for the cost of saving water are presented for several important parameters.
