Organic Geochemistry Research Core Technology Team
About the Research The Organic Geochemistry Research Laboratory Core Technology Team (CTT) as part of the Environmental Health Program works to develop targeted and non-targeted analytical methods for the identification and quantitation of chemicals that can impact the health of humans and other organisms, and uses bioassays to screen for receptor inhibition.
Digital Polymerase Chain Reaction (dPCR) and Presence/Absence Quantitative Polymerase Chain Reaction (qPCR) Data From the Sediment-Bound Contaminant Resiliency and Response Strategy Pilot Study, Northeastern United States, 2015 Digital Polymerase Chain Reaction (dPCR) and Presence/Absence Quantitative Polymerase Chain Reaction (qPCR) Data From the Sediment-Bound Contaminant Resiliency and Response Strategy Pilot Study, Northeastern United States, 2015
The purpose of these data sets was to define which samples contained antibiotic resistance genes (screened antibiotic resistance gene targets) and Vibrio species, the number of detectable targets per sample and the quantity of those respective gene targets per gram of soil. These data were determined from samples collected in the NE US in support of the Sediment-bound Contaminant...

Public, bottled, and private drinking water: Shared contaminant-mixture exposures and effects challenge Public, bottled, and private drinking water: Shared contaminant-mixture exposures and effects challenge
BACKGROUND: Humans are primary drivers of environmental contaminant exposures worldwide, including in drinking-water (DW). In the United States (US), point-of-use DW (POU DW) is supplied via private tapwater (TW, predominantly private wells), public-supply TW, and bottled water (BW). Differences in management, monitoring, and messaging and lack of directly intercomparable exposure data...

Interdisciplinary science approach for harmful algal blooms (HABs) and algal toxins—A strategic science vision for the U.S. Geological Survey Interdisciplinary science approach for harmful algal blooms (HABs) and algal toxins—A strategic science vision for the U.S. Geological Survey
Executive Summary Algal blooms in water, soils, dusts, and the environment have captured national attention because of concerns associated with exposure to algal toxins for humans and animals. Algal blooms naturally occur in all surface-water types and are important primary producers for aquatic ecosystems. However, excessive algae growth can be associated with many harmful effects...

Integrated science for the study of microplastics in the environment—A strategic science vision for the U.S. Geological Survey Integrated science for the study of microplastics in the environment—A strategic science vision for the U.S. Geological Survey
Executive Summary Evidence of the widespread occurrence of microplastics throughout our environment and exposure to humans and other organisms over the past decade has led to questions about the possibility of health hazards and mitigation of exposures. This document discusses nanoplastics as well as microplastics (referred to solely as microplastics); the microplastics have a range from...

Water, water everywhere, but every drop unique: Emerging challenges in the science to understand the role of contaminants in management of drinking water supplies Water, water everywhere, but every drop unique: Emerging challenges in the science to understand the role of contaminants in management of drinking water supplies
The protection and management of water resources continues to be challenged by multiple and ongoing factors such as shifts in demographic, social, economic, and public health requirements. Physical limitations placed on access to potable supplies include natural and human-caused factors such as aquifer depletion, aging infrastructure, saltwater intrusion, floods, and drought. These...

Exposures and potential health implications of contaminant mixtures in linked source water, finished drinking water, and tapwater from public-supply drinking water systems in Minneapolis/St. Paul area, USA Exposures and potential health implications of contaminant mixtures in linked source water, finished drinking water, and tapwater from public-supply drinking water systems in Minneapolis/St. Paul area, USA
Continued improvements in drinking-water quality characterization and treatment/distribution infrastructure are required to address the expanding number of documented environmental contaminants. To better understand the variability in contaminant exposures from the drinking water resource (surface and groundwater), through the distribution process, to the point-of-use (tapwater), in 2019...

Juxtaposition of intensive agriculture, vulnerable aquifers, and mixed chemical/microbial exposures in private-well tapwater in northeast Iowa Juxtaposition of intensive agriculture, vulnerable aquifers, and mixed chemical/microbial exposures in private-well tapwater in northeast Iowa
In the United States and globally, contaminant exposure in unregulated private-well point-of-use tapwater (TW) is a recognized public-health data gap and an obstacle to both risk-management and homeowner decision making. To help address the lack of data on broad contaminant exposures in private-well TW from hydrologically-vulnerable (alluvial, karst) aquifers in agriculturally-intensive...

U.S. Geological Survey COVID-19 Wastewater Surveillance U.S. Geological Survey COVID-19 Wastewater Surveillance
USGS, as part of the National Wastewater Surveillance System, designed and implemented high-frequency sampling of wastewater across six states throughout September 2021, to support tracking of potential increases in COVID-19 infections in communities. COVID-19 viral loads were determined for each sample with the goal of delivering results to the CDC within three days of sampling.
