Abstract Contamination from anthropogenic activities is a long-standing challenge to the sustainability of groundwater resources. Physically based (PB) models are often used in risk assessments, but their application large scale problems requiring high spatial resolution remains computationally intractable. Machine learning (ML) have emerged as an alternative PB era big data, necessary number observations may be impractical obtain when events rare, such episodic contamination incidents. The...
Background: Unconventional oil and gas development (UOGD) releases chemicals that have been linked to cancer childhood leukemia. Studies of UOGD exposure leukemia are extremely limited. Objective: The objective this study was evaluate potential associations between residential proximity risk acute lymphoblastic (ALL), the most common form leukemia, in a large regional sample using UOGD-specific metrics, including novel metric represent water pathway. Methods: We conducted registry-based...
Health studies report associations between metrics of residential proximity to unconventional oil and gas (UOG) development adverse health endpoints. We investigated whether exposure through household groundwater is captured by existing a newly developed metric incorporating flow paths. compared with detection frequencies/concentrations 64 organic inorganic UOG-related chemicals/groups in from 255 homes (Pennsylvania n = 94 Ohio 161). Twenty-seven chemicals were detected ≥20% water samples...
The expansion of unconventional oil and gas development (UOGD), made possible by horizontal drilling hydraulic fracturing shale formations, has fostered economic benefits in the United States (US), increasing domestic energy supplies exports for international markets. At same time, local concerns about risks posed this industry on environment public health persist, especially regarding potential contamination drinking water communities that depend aquifers daily use. Quantifying such at...
In the wake of disasters, storytelling can function as a means for collective sensemaking, trauma recovery, and community-centered knowledge co-production. Through practice listening medium voice, audio stories convey culturally specific that engages emotions while fostering dialogic thinking on complex topics. Here, we detail our experience in research producing public-facing story series about communities facing displacement loss from water-related disasters. First, traveled 2023 to...
Abstract The rapid expansion of unconventional oil and gas development (UD), made possible by horizontal drilling hydraulic fracturing, has triggered concerns over groundwater contamination public health risks. To improve our understanding the risks posed UD, we develop a physically based, spatially explicit framework for evaluating well vulnerability to aqueous phase contaminants released from surface spills leaks at UD pad locations. proposed utilizes concept capture probability...
Concerns over unconventional oil and gas (UOG) development persist, especially in rural communities that rely on shallow groundwater for drinking other domestic purposes. Given the continued expansion of industry, regional (vs local scale) models are needed to characterize contamination risks faced by increasing proportion population residing areas accommodate UOG extraction. In this paper, we evaluate vulnerability from surface spills subsurface leakage wells within a 104,000 km2 region...
Unconventional oil and gas (UOG) development, made possible by horizontal drilling high-volume hydraulic fracturing, has been fraught with controversy since the industry's rapid expansion in early 2000's. Concerns about environmental contamination public health risks persist many rural communities that depend on groundwater resources for drinking other daily needs. Spatial disparities UOG can pose distributive injustice if such are disproportionately borne marginalized communities. In this...
Agricultural terraces are the most evident landscape imprints of traditional knowledge on soil conservation and water management globally. This article focuses Ifugao Rice Terraces (IRT) Philippines, a sustainable agroecosystem built harmonious relationship between indigenous people their local environment. We elucidate how rice influence hydrologic response at small catchment scale through detailed field monitoring physically based mathematical modeling. also explore consequences...
Domestic wells serve as the primary drinking-water source for rural residents in northern Appalachian Basin (NAB), despite a limited understanding of contaminant distributions groundwater sources. We employ newly collected dataset 216 water samples from domestic Ohio and West Virginia an integrated contaminant-source attribution method to describe quality western NAB characterize key agents influencing distributions. Our results reveal arsenic nitrate concentrations above federal maximum...
Hydrogeologic transport contributes to limited organic chemical contamination in a region of intense gas extraction, even 10 years post-development.
Conflicting evidence exists as to whether or not unconventional oil and gas (UOG) development has enhanced methane transport into groundwater aquifers over the past 15 years. In this study, recent samples were collected from 90 domestic wells 4 springs in Northeastern Pennsylvania located above Marcellus Shale after more than a decade of UOG development. No statistically significant correlations observed between level various geospatial metrics, including proximity well violations, number...
The production of fossil fuels, including oil, gas, and coal, retains a dominant share in US energy serves as major anthropogenic source methane, greenhouse gas with high warming potential. In addition to directly emitting methane into the air, fuel can release groundwater, that may eventually reach atmosphere. this study, we collected 311 water samples from an unconventional oil (UOG) region Pennsylvania (O&G) coal across Ohio West Virginia. Methane concentration was negatively correlated...
Abstract Water transit time is the duration between entry and exit of a parcel water across hydrologic system. It fundamental characteristic that links transport, biogeochemical processing, quality, it has broad implications for resource vulnerability sustainability. Physically based models can accurately describe distributions but require significant computational resources when applied to large regions at high resolutions. In this study, we evaluate potential machine learning metamodels...
Approximately 30 epidemiologic studies of unconventional oil and gas development (UOG) to date have identified associations with adverse health outcomes, such as birth asthma, cancer. These used spatial surrogates exposure, which are feasible approaches for assessing aggregate exposures in large-scale studies. However, pathways captured by these (e.g., water contamination, air pollution) poorly understood. We logistic linear regression assess whether commonly-used were associated UOG-related...
Abstract Background Strong governance and regulatory supervision are required to conduct research in an emergency context ensure compliance with ethical standards. Preparedness response rely on the formalization, structure, function of national ethics systems. The Strengthening oversight Central America Dominican Republic COVID-19 pandemic (GoEtiCA) study is a regional effort addressing challenges during pandemic. This describes that addresses specific humanitarian health caused by COVID-19;...
