Unconventional oil and gas development and risk of childhood leukemia: Assessing the evidence.

A young girl with leukemia, wearing a hoody over her bald skull and breath protector.

The findings of this literature review support the need for investigation into the relationship between UO&G development and risk of cancer in general and childhood leukemia in particular. Abstract The widespread distribution of unconventional oil and gas (UO&G) wells and other facilities in the United States potentially exposes millions of people to air and water …

Identifying chemicals of concern in hydraulic fracturing fluids used for oil production

Based on an analysis of quantities used, toxicity, and lack of adequate hazard evaluation, QACs, biocides, and corrosion inhibitors were identified as priority chemicals of concern that deserve further investigation. Abstract Chemical additives used for hydraulic fracturing and matrix acidizing of oil reservoirs were reviewed and priority chemicals of concern needing further environmental risk assessment, …

Quantity of flowback and produced waters from unconventional oil and gas exploration

Key findings: Estimated flowback and produced water volume from unconventional oil and gas wells is 1.7 to 14.3 million liters per well. Only a small fraction (4-8%) of the flowback and produced waters is composed of returned injected hydraulic fracturing fluids. The majority (92-96%) of flowback and produced waters is composed of naturally occurring formation …

Managing the Increasing Water Footprint of Hydraulic Fracturing

Scheme: Water use in hydraulic fracturing.

The water footprint of oil production, including water used for hydraulic fracturing (HF) and flowback-produced (FP) water, is increasingly important in terms of HF water sourcing and FP water management. This study evaluates trends in HF water use relative to supplies and FP water relative to disposal using well by well analysis in the Bakken …

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 …

Brine Spills Associated with Unconventional Oil Development in North Dakota

This study of the Duke University’s Nicolas School of the Environment shows widespread water and soil contamination caused by more than 3.900 wastewater spills from unconventional oil production in North Dakota. Researchers found high levels of ammonium, selenium, lead and other toxic contaminants as well as high salts in the brine-laden wastewater, which primarily comes …
