A sorbent-based approach to managing pollutants in urban stormwater runoff


Narges Esfandiar, Rominder Suri, Erica R. McKenzie

ABSTRACT:

Urban storm water runoff can contain potentially harmful contaminants including nutrients, metals, and polycyclic aromatic hydrocarbons (PAHs). Each of these pollutants are found in urban stormwater runoff and has the potential to detrimentally impact ecosystem and/or human health.  Under the green stormwater infrastructure stormwater management approach, infiltration-based stormwater management practices are increasingly being employed.  However, to mitigate the potential negative effects of these pollutants, incorporating sorbents into the SMP media is sometimes considered as a means of promoting pollutant retention.  Laboratory testing undertaken in this project simultaneously evaluates the removal of nutrients, metals, and PAHs, recognizing that the chemistries of these pollutants vary widely.  Five sorbents were selected for evaluation, with emphasis toward commercially available materials and particularly those that are providing reusing opportunities for a waste-stream – biochar, iron amended biochar, scrap tire, coconut coir, and iron chips.  The laboratory batch studies evaluated sorption kinetics and equilibrium capacity.  Discussion of the results from this study will highlight strengths and limitations of each sorbent, appropriate selection of sorbent, and on-going testing.  

SPEAKER BIO: Erica R. McKenzie

Erica McKenzie was originally attracted to environmental engineering to better understand human impacted natural environments. In the course of her studies, she earned degrees at University of California at Davis and Colorado State University, she completed NSF summer Research Experience for Undergraduate (REU) experiences at University of Notre Dame and the Center for Biofilm Engineering at Montana State University, and she conducted research as a postdoctoral scholar at Colorado School of Mines and the Western Cooling Efficiency Center at UC Davis. Dr. McKenzie joined the Civil and Environmental Engineering Department at Temple University in January 2015.  At Temple University, her group conducts experimental research on chemical contaminant fate and transport, particularly focusing on stormwater (many pollutants) and poly/perfluoroalkyl substances (many systems).

Engineers:

This seminar does qualify for 1.0 Professional Development Hour (PDH). A Certificate of Attendance will be available on site for AWRA-PMAS members only. The meeting price for non-members who wish to receive a Certificate of Attendance for the PDH is $10.00 ($3.00 for meeting + $7.00 for certificate). 

 

Please note: all lunch orders will close by noon on the day before the presentation. In addition, all lunch orders will need to be paid for online by this time. We are unable to refund the cost of lunch or meeting fees because they are paid ahead of time based on number of registrations.


Reminder that registration is open for the 2019 Villanova University Biennial Symposium:
