Mike Abraczinskas Mike Abraczinskas
Director, Div. of Air Quality
North Carolina Department of Environmental Quality

 

Mike Abraczinskas is currently the Director of the North Carolina Division of Air Quality (DAQ). Mike has 22 years of experience in air quality (over 20.5 with DAQ), including regulatory development, planning, emissions and air quality modeling, and compliance activities. Mike worked in 7 different positions in DAQ prior to being named Director in March of 2017. He graduated from North Carolina State University; is certified as an Engineer-In-Training (EIT); and is a graduate of the North Carolina Public Managers Program. Mike is currently serving in leadership positions of several regional organizations comprised of State and Local Air Quality Agencies:
• Past Chairman for the Southeastern States Air Resource Managers (SESARM)
• Chairman of the Mid-Atlantic Regional Air Management Association (MARAMA)
• Board member of the Carolinas Air Pollution Control Association (CAPCA)

Additionally, Mike is actively involved in the activities of the Association of Air Pollution Control Agencies (AAPCA).



PLATFORM PRESENTATION

Emerging Compounds from an Air Perspective: A Case Study of Atmospheric Deposition of PFAS/GenX

Measurements of a per- and polyfluoroalkyl substance (PFAS), C3 Dimer Acid or GenX, were made in the Cape Fear River in North Carolina. The source of the GenX was a Chemours chemical facility in Bladen County, North Carolina. Industrial discharges to the Cape Fear River contributed to the compound’s measurement in the river and water system intake sites along the river to Wilmington North Carolina. Residential drinking wells nearfield to the facility were sampled and the results also indicated the GenX compound in the groundwater. Further investigation into the air emissions from the facility, including a requirement for first of its kind source testing, assisted in understanding the facility’s air emissions contribution of GenX to the groundwater. Air dispersion and deposition modeling was coupled with well sampling to evaluate the field of contamination. Although ambient air measurement of GenX was deemed to be difficult, measurement of GenX in water was possible. Ultimately rainwater sampling was performed by Division of Air Quality staff near the facility during several rain events in early 2018. The results indicated atmospheric deposition of GenX. Further investigations measured GenX deposition through rainwater measurements at high concentrations at distances downwind of the facility. GenX was measured in rainwater as far as twenty-one miles from the facility. Measurements from the sampling in early 2018 helped to develop a baseline for deposition. Fixed wet/dry deposition sites were established in April 2018 and weekly samples have been analyzed ever since. The facility has added emissions controls (interim measures in 2018) and longer term solutions in late 2019. The deposition data has been evaluated from periods before, during and after the installation of the emissions controls.
