The association between oil and natural gas extraction processes and human reproduction

This review of the current literature makes clear: The impact of unconventional oil and gas activities may be greater than that of conventional activity, given that unconventional activities employ many of the same approaches and use dozens of known endocrine-disrupting chemicals in hydraulic fracturing. Abstract: This systematic review identified 45 original published research articles related …

When the wind blows: tracking toxic chemicals in gas fields and impacted communities

When the Wind Blows: Tracking Toxic Chemicals in Gas Fields and Impacted Communities is a report documenting Coming Clean’s collaborative, community-based research project to monitor toxic volatile organic compounds (VOCs) in gas fields in rural Pavillion, Wyoming and to see what same VOCs are present in the bodies of people who work and live there. …

Indications of Transformation Products from Hydraulic Fracturing Additives in Shale-Gas Wastewater

This study by a German-US research team investigated six Fayetteville Shale wastewater samples for organic composition. Its results highlight the possibility that unconventional natural gas development (UNGD) operations generate transformation products and underscore the value of disclosing additives injected into the subsurface. UNGD generates large volumes of wastewater, the detailed composition of which must be …

Estimating the Potential Toxicity of Chemicals Associated with Hydraulic Fracturing Operations

The United States Environmental Protection Agency (EPA) identified 1,173 chemicals associated with hydraulic fracturing fluids, flowback, or produced water, of which 1,026 (87%) lack chronic oral toxicity values for human health assessments. This work aims to facilitate the ranking and prioritization of chemicals that lack toxicity values using several different methodologies. Bibliography: Yost EE, Stanek …

Spills of Hydraulic Fracturing Chemicals on Agricultural Topsoil

Hydraulic fracturing frequently occurs on agricultural land. Yet, the extent of sorption, transformation, and interactions among the numerous organic frac fluid and oil and gas wastewater constituents upon environmental release is hardly known. This study aimed to advance our current understanding of processes that control the environmental fate and toxicity of commonly used hydraulic fracturing …

Wastewater Disposal from Unconventional Oil and Gas Development Degrades Stream Quality…

This study is, up to now, the second investigation which turned up direct negative impacts of underground disposal of wastewaters from unconventional oil and gas (UOG) production on surface waters in West Virginia. Although the hydrologic pathways could not be assessed, the study’s findings show that activities at the disposal facility are impacting a nearby …
