Environmental air-borne particulate matter (APM) samples were collected at two locations surrounding the Department of Energy’s Waste Isolation Pilot Plant (WIPP) near Carlsbad, NM in 2019. Cellulose-based Whatman 41 filters were utilized for APM collection from approximately 17,000 m3 of air with associated climate conditions (i.e., ambient temperature, wind speed, wind direction, humidity, and rain fall). Amounts of associated common anions were determined using ion chromatography of aqueous extracts from each sample. Specifically, fluoride, chloride, bromide, nitrate, nitrite, phosphate, and sulfate ions were determined. The results of samples collected throughout 2019 were analyzed in conjunction with the corresponding meteorological data for samples collected at each of the two locations relative to the WIPP site using Principle Component Analysis and Factor Analysis. The results of this study will be presented. The implications of weather conditions on APM sample anion analysis and data interpretation will be discussed.
