Bioindicator, Bioaccumulation, and Fish Community Studies
Fish are collected and analyzed for physiological health, contaminant accumulation, and population analyses.
Benthic Macroinvertebrate Studies
Benthic macroinvertebrate communities are studied to assess ecological condition and recovery.
The toxicity of water, sediment, and soils are evaluated
The Biological Monitoring and Abatement Program began in the mid-1980s to evaluate stream ecological conditions. The comprehensive long-term program has added significantly to the scientific understanding of ecological recovery from industrial pollution
Wetland and Stream Mitigation
Wetland delineation and mitigation studies, including innovative out-of-kind mitigation, are implemented at multiple Department of Energy and Department of Defense sites.
Plant management activities include controlling invasive plant species and native plant restoration (including prairies, forests, and ponds).
Oak Ridge Reservation wildlife management includes surveys and protection of rare wildlife species and habitat, control of nuisance species, and contaminant monitoring.
Ultra sensitive analytical techniques are applied to evaluate remediation performance.
New remediation technologies and approaches are developed for mitigating mercury problems in aquatic systems.
Caged Asiatic clams and semi-permeable membrane devices are used successfully to identify discrete sources of PCBs.
Ecological Management and Enhancement
ORNL scientists developed an innovative remediation strategy, the first of its kind approved by EPA, to interrupt contaminant exposure pathways while enhancing habitat quality.
Fish protection and mitigation options are tested at field sites.
The aquatic ecology laboratory is used to simulate impacts from power plants, such as high temperature and impingement, on fish health and survival.
Power Plant Impacts
The environmental impacts of hydro- and thermoelectric power production on fish populations are evaluated in the lab and field.
Rare Species Status
New techniques for evaluating threatened and endangered species status have been developed by ORNL scientists, including the use of statistical sampling designs and a physiological-based framework for assessing species health.
A Military Ecological Risk Assessment Framework has been applied to evaluate the effects of tracked vehicles on desert hydrology and wash vegetation.
Decision Support for the Department of Defense
ORNL scientists support the military's environmental stewardship activities by helping develop and apply risk assessment tools, low impact development strategies, and ecological sampling designs.
Sophisticated models are developed and applied to assess impacts on aquatic resources at a wide range of spatial and temporal scales.
The Walker Branch Watershed is one of few sites in the world characterized by long-term, intensive environmental studies of hydrologic processes in a forested watershed.
ORNL scientists contribute to a better understanding of processes that regulate global atmospheric cycling and bioaccumulation of mercury in aquatic ecosystems.
