We never know the worth of water till the well is dry.  ~Thomas Fuller

According to the World Health Organization there are around 1 billion people in the world who do not have access to clean drinking water and 2.6 billion people who lack proper sanitation.  Texas A&M University engineering professor, Bryan Boulanger, and graduate research assistant, Ishan Desai, are hoping to change this outlook by incorporating nanotechnology into treatment systems used throughout the world.  Nanotechnology is the science that deals with particles of matter smaller than 100 nanometers. Nanotechnology based treatment alternatives are an emerging field of water purification science that has the potential for treating water and wastewater quickly, efficiently, and at lower future costs. 

Research performed by Boulanger and Desai is focused on evaluating the ability of such nanoscale metal oxide particles to remove common water contaminants such as heavy metals (arsenic, mercury, cadmium, and chromium), anions (nitrates, nitrites, phosphates, bromide, chloride, and fluoride), and organics (DDT, TCE, PCE, antibiotics and hormones) from source waters. The main objective of their research is to evaluate the fundamental factors affecting surface chemistry occurring between the nanoparticles and contaminants.  By thinking small, the researchers hope to have a big impact and provide useful solutions to solve the growing potable water crisis.
