The rural city of Uniontown, Alabama has suffered differential burdens of air, water, and soil contamination compared to all other municipalities in Perry County. The town's population is approximately 90% African American with a per capita income of less than $10,000 and nearly 40% of residents living below the poverty line. Residents' health concerns stem from high rates of cancer, respiratory illness, kidney disease, and neuropathy and emissions from the town's three industrial entities: the Arrowhead Landfill, a 425-acre "megafill" accepting waste (notably coal ash, a carcinogen-rich coal combustion residue) from 33 states; the Harvest Select Catfish feedmill and processing plant whose high daily output of wastewater overloads the municipal infrastructure; and the Southeastern Cheese Corporation cheese production plant and its associated cheese wastewater sprayfields. Additionally, high diesel truck traffic to and from each of these locations presents high likelihood of chronic volatile organic compound (VOC), black carbon (BC), and particulate matter (PM) exposures. In 2019, the University of Maryland School of Public Health partnered with Black Belt Citizens Fighting for Health and Justice, a community-based organization in Uniontown, to design and implement a community science network of low-cost air quality monitors. Guided by the principles of community-based participatory research, the partners have hosted community listening sessions around air quality concerns, training workshops on air pollution sampling and environmental hazard risk reduction, and deployed 15 PurpleAir particulate matter monitors. Results discussed include making the case for environmental injustice in Uniontown, community engagement and community-university partnership pitfalls and best practices, as well as analyses of data from more than 12 consecutive months of air quality monitoring.
