Welcome to the NTAEP home page. Our group is composed of environmental professionals from the greater Dallas-Fort Worth, Texas Metroplex. Our group meets during the lunch hour on the third Wednesday of each month except for the summer months of June through August. Our meetings feature a speaker and time for networking. See below for upcoming meetings and go ahead and register if you like! We hope you can join us soon!
If you would like to see our exciting upcoming events or view a presentation from a previous meeting, please see our Recent News! NTAEP also offers a scholarship to students with an environmental science major - find out more here.

Dr. Sasha S.K. Jones will be presenting MultiSorb Development for
Leachate and Wastewater Treatment."
Sasha S.K. Jones, Ph.D.
Scientific Apparatus Engineering Technician, Department of Civil Engineering, University of Texas at Arlington
Dr. Sasha S.K. Jones holds a Ph.D. in Earth & Environmental Science from the University of Texas at Arlington. Her research focuses on sustainable and cost-effective methods for waste management and remediation of contaminated environments, with a particular interest in developing countries. She has investigated both phytoremediation combined with soil amendments for contaminated open dumpsites and the development of “MultiSorb” sorbent mixtures from waste materials for heavy metal and organic removal in wastewater and leachate.
​
In addition to her research, Dr. Jones brings over 15 years of teaching experience at both high school and university levels, and more than a decade of leadership in training, coordinating, and managing personnel. She is also the founder of CrossFit Green Leaf, combining her scientific expertise with community-building and wellness initiatives.
​
Her work has been supported by the U.S. Department of Agriculture National Institute of Food and Agriculture (USDA-NIFA) under the direction of Principal Investigator Dr. Mithila Chakraborty.

Presentation Summary
​
-
MultiSorb Development for Leachate and Wastewater Treatment
This USDA-funded project developed MultiSorb, a multiple sorbent mixture synthesized from readily available waste materials, to cost-effectively remove heavy metals and organics from leachate and wastewater.
​
Advantages of MultiSorb Over Traditional Treatment Methods
​
-
Cost-Effectiveness: Unlike commercial methods such as activated carbon (AC), which can be costly, MultiSorb uses low-cost, locally available materials (e.g., rice husks and sewage sludge), making it potentially affordable for large-scale use in resource-limited regions.
-
Broad Range of Contaminants: In lab testing, MultiSorb was able to pollutants from various categories, including PFAS, pharmaceuticals, and personal care products (PPCPs). Traditional treatments often target only one contaminant class.
-
Efficiency: Research findings demonstrate that MultiSorb performed comparable to activated carbon in removing selected PFAS and PPCPs from wastewater. Column testing under continuous-flow conditions confirmed its effectiveness for these selected compounds.
