An ecosystem approach to assessing unconventional oil and gas impacts in aquatic ecosystems

Science Center Objects

The development of unconventional oil and gas (UOG) technology promises economic, societal and national security benefits.  However, technological developments in this field have rapidly outpaced scientific studies on potential environmental effects.  The effects of accidental UOG-related spills on environmental health are not adequately characterized, often occur in already ecological sensitive locations (e.g. headwater streams, areas supporting threatened species), and may involve multiple aspects of the stream ecosystem. 

USGS researchers, along with collaborators, have been conducting a large-scale outdoor raceway study to assess the acute and chronic effects of UOG waste on multiple compartments of the headwater ecosystems.  These studies range in biological scale and include assessments of multiple endpoints including gene expression, fish health, microbial activity, nutrient dynamics, and trophic interactions.

Stream raceway

USGS researchers have simulated replicated headwater streams in outdoor raceways to evaluate the ecological effects of UOG waste spills.

Collecting UOG waste

USGS researchers use an assembly line strategy to collect as much data as possible.  Here, researchers are evaluating the effects of UOG waste on brook trout disease and body condition.

Measuring fish

USGS researchers evaluated the role of UOG waste on brook trout health, including growth rate.  Here, Barbara White is measuring a juvenile brook trout used in this study.
