Ariel Robinson KC Donnelly Abstract:
Together, UKSRC Project 4 and NCState Project 4, combine to provide a beneficial opportunity
for my KC Donnelly Externship. I will learn sampling and analytical procedures related to PFAS.
Various industries discharge wastewater to wastewater treatment plants (WWTP) through a
complex interconnected network of piping infrastructure that the UKSRC team has mapped
using GIS software. Industrial discharges are regulated by industrial pretreatment permit
programs and by the National Pollutant Discharge Elimination System (NPDES). Industrial
pretreatment programs pretreat wastewater to reduce contaminant concentrations before the
water reaches a surface water. Most wastewater treatment plants do not have capacity to treat
PFAS. Therefore, PFAS leaves WWTP and are discharged to surface water bodies, which
serve as drinking water sources. In Kentucky, over 70% of the drinking water sources come
from surface water sources. Some of the drinking water plants use GAC, but not many.
Although, GAC is being considered as a PFAS treatment option.
Specific Aim 1. To learn sample preparation for water samples that contain various
volatile and semi-volatile PFAS for analysis by mass spectrometry. Experiments using
samples from NCState’s Project 4 will be the focus of this aim. Experienced graduate students
under supervision of Dr. Detlef Knappe will provide me training on sample preparation methods
used during these experiments
Specific Aim 2. To learn chemical analysis for water samples being analyzed for PFAS
using high- and low-resolution mass spectrometry. Under the direction of Dr. Detlef
Knappe, I plan to learn the analytical workflow of PFAS chemicals, behavior of PFAS chemicals
within the ion source, and expand my knowledge of PFAS analysis from standard EPA
methods.
