Water Security and Sustainability

Innovative methods are being developed for the treatment of wastewater and to ensure that water quality is maintained. 

The overarching objective of this thrust area is to enable fundamental and applied research on topics aimed toward conserving the quantity and enhancing the quality of our water resources.    

          

Water Security Research Leader  

This is being done through the assessment and development of innovative water and wastewater treatment technologies; understanding the impact of stormwater runoff on watershed health; the use of an integrated watershed management approach; and groundwater quality assessment. 

Research Focus Area Leader: Dr. Tania Datta, Tennessee Tech Water Center
