Description:

Objective:

One of the most serious problems along the U.S.A.-Mexican border is the lack of access to adequate quality drinking water. The groundwater from wells in Columbus, NM and Palomas, Mexico border region contains significantly high levels of fluoride and arsenic that could potentially cause many serious diseases for the residents, especially young children in this border region. There is an urgent need for purifying the drinking water supplied by the municipals to protect the health of the residents in the border region. Preliminary results from the PI’s research have shown that the sol-gel derived mesoporous alumina-based adsorbent can effectively adsorb both arsenic and fluoride from water. The specific goal of this project is to demonstrate the feasibility of using the mesoporous alumina-based adsorbent for removing both arsenic and fluoride from well waters in Columbus, NM and Palomas, Mexico. Activated alumina-based adsorption systems will be installed in both U.S.A. and Mexico well sites. This technology can be used either in large water treatment plants for municipals and/or the Point-of-Use for individual households. The main technical objective is to remove arsenic and fluoride from groundwater to below 10 μg/L and 4 mg/L, respectively.

Approach:

This project aims at reducing the arsenic and fluoride from groundwater in Columbus, NM and Palomas, Mexico border region to below 10 μg/L and 4 mg/L, respectively.

  • Synthesize 2-3 kg of mesoporous alumina with a sol-gel method;
  • Determine adsorption properties of arsenic and fluoride on the alumina;
  • Test the alumina adsorption system in Columbus, NM and Palomas, Mexico.

Expected Results:

  • Novel adsorbents with high arsenic and fluoride adsorption capacity;
  • An effective water purification system for the Columbus, NM and Palomas, Mexico region.
  • Excellent training and experience on drinking water purification for the participating students.
