Our group’s long-term collaborative vision is to address community specific water and energy needs by developing programs that couple innovative education approaches and appropriate technology based solutions needed to improve communities and achieve sustainability. We are currently focused on three areas of research/outreach:
1. Risk management of environmental contaminants 2. Sanitation & Water Treatment Alternatives 3. Alternative fuels development

Children’s Safe Drinking WaterDr. Greg Allgood,
Contaminated drinking water is a major problem. More than one billion people do not have access to safe water. Diarrhea caused by drinking contaminated water remains a leading cause of illness and death among infants and children in the developing world. About 1.8 million children die every year due to diarrheal diseases. More children die from diarrheal illnesses like cholera and dysentery than from HIV/AIDS or malaria combined. There is conclusive evidence that simple, low-cost interventions at the community level can dramatically improve the quality of household stored water and greatly reduce the risk of diarrheal disease and death. It is well documented that simply providing safe, clean, drinkable water can reduce deadly diarrhea and other devastating diseases by about 50%.

What did they find?84% of phenotypic females in the wild salmon tested positive for the male genetic marker. In contrast, none of the hatchery raised females tested positive.
Offspring spawned by mating of real males with sex-reversed males would be either XY or YY instead of all XY, the outcome of normal male to normal female mating. YY would never happen normally. This would lead to a steady decrease in the number of normal females in the population. The fact that only 16% of females were normal (and some if not all of those may have been hatchery, not wild), appears consistent with that prediction.

Julianne Camacho- working with undergraduate students on a NASA project:
NASA’s future plans for long-term spaceflight will require a constant food and water supply. Consequently, a system must be developed to recover water in order to make longterm spaceflight feasible. Prior to collection, urine is pretreated in order to prevent cloggingof the small diameter collection tubes by biofilm formation and solids precipitation.

Urine Pretreatment for Biological Water Recovery
Objective:Identify a non-toxic
pretreatment alternative that is compatible with a
biological water reclamation system.

But really, why are they doing this?????

What am I doing here????
We have visited with our graduate students and Dr. Boulanger about all the projects that they are working on. We have chosen to work on water treatment for human use.
We will be working on the NASA project and on developing a filter that will remove arsenic from water that has been run through the ceramic filter. The ceramic filter will remove the biological contaminants and will remove debris but has not been shown to remove the arsenic that is found in the water of South Texas. We are working on a filter that will be located in front of the spigot that will have a catalyst that will remove arsenic from the drinking water.
I also have been privileged to go to East Texas and tag along while a group of students from Eastfield College in Dallas did environmental research. I met people that work in the area of my high school that are interested in collaborating with us to create an outdoor classroom and to help me in other areas with my students.
