Jason Masoner
Jason conducts field-based research to study the fate, transport, and effects of environmental contaminants in municipal and industrial waste products that are disposed or reused for potential beneficial reuse purposes.
The focus of my work is primarily on environments that have been substantially disturbed by human activities. Such disturbances are frequently associated with sources containing complex mixtures of inorganic and emerging contaminants that have the potential to negatively impact both ecological and human health. More specifically, I seek to address the environmental issues that attend the management of urban stormwater runoff, municipal waste (landfills, domestic sewage) and oilfield wastes (drill cuttings, fluids, produced water). Overall, my research goal is to provide reliable and unbiased scientific information to environmental quality decision makers world-wide.
Science and Products
A National Assessment of Pesticide, PFAS, Microplastic, and Antibiotic Resistance Gene Exposures in White-Tailed Deer
Research has documented exposures and consequential environmental health effects of pesticides, PFAS, microplastics, and antibiotic resistance genes in environmental biota. Little is known, however, regarding such effects in white-tailed deer ( Odocoileus virginianus).
Organic Contaminants in Reuse Waters and Transport Following Land Application
Potential reuse waters contained unique mixtures of organic contaminants with the greatest number detected in treated municipal wastewater treatment plant effluent, followed by urban stormwater, and agricultural runoff. This study provided information for decisions on reuse strategies to support freshwater supplies.
Ongoing Research to Characterize the Complexity of Chemical Mixtures in Water Resources—Urban Stormwater
A multiagency reconnaissance study of chemicals in urban stormwater, sampled from pipes or ditches during 50 runoff events at 21 sites in 17 states across the United States, demonstrated that stormwater runoff contains complex mixtures of chemicals including polycyclic aromatic hydrocarbons, pesticides, and pharmaceuticals that are indicative of multiple sources in the watershed.
Green Infrastructure, CECs, and Geochemistry in Urban Stormwater Runoff used to Recharge Groundwater
This national project is a joint effort between the USGS and EPA looking at contaminants of emerging concern (CECs) in urban stormwater runoff that is infiltrated into the subsurface or likely to be infiltrated in the future. Phase I of the project aims to provide a broad-scale assessment of contaminants of emerging concern (CECs) and basic composition of water chemistry in urban stormwater runoff...
Distinct Microbiomes Identified in Landfills Throughout the United States
A comprehensive study by U.S. Geological Survey (USGS) and scientists from the University of Oklahoma finds distinct microbial assemblages (microbiomes) in landfill leachate across the United States and investigates factors related to microbiome formation.
Landfill Leachate Released to Wastewater Treatment Plants and other Environmental Pathways Contains a Mixture of Contaminants including Pharmaceuticals
New scientific research from the U.S. Geological Survey (USGS) details how landfill leachate, disposed from landfills to environmental pathways, is host to numerous contaminants of emerging concern (CECs).
