Ecological
Risk Assessment incorporates a combination of field and laboratory-derived
information. ardea consulting interprets
these field and laboratory results to provide a complete picture of
any ecological risk to birds and other wildlife. We can also collect
additional data to complete the assessment as necessary. Assessments
are suitable for submission to the U.S. EPA and other regulatory agencies.
ardea consulting researches and writes
the entire Ecological Risk Assessment or provides avian or wildlife
toxicology input as part of a team. ardea
presents a summary of any ecotoxicology data gaps with suggestions on
ways to fill the gaps, and then conducts any required field work..

Sample
Projects: |
|
Project
#1: |
Problem: A client was creating a mitigation wetland on agricultural lands adjacent to a steelhead stream.
Solution: An ecological risk assessment was performed to determine whether fish or wildlife that might be attracted to the wetland would be at greater risk after the construction of the wetland.
Result: The assessment indicated that the upper foot of soil in the agricultural lands contained legacy pesticides at concentrations sufficient to be harmful to fish or wildlife. ardea recommended removing the upper layer of soil prior to creating wetland. Report is available on the Technical Reports page of this website. |

Project
#2: |
Problem:
A manufacturing site requires clean-up criteria be based
solely on ecological endpoints.
Solution: Compare soil and sediment contaminant
levels to established toxicity reference values.
Result:
A site evaluation of bird and mammal species present on
the site was performed to determine species at risk to exposure. |

Project
#3: |
Problem:
A manufacturer needed to conduct an ecological risk assessment
on a new product.
Solution: The suite of skills needed for the project
dictated a team approach. ardea
consulting reviewed laboratory and field studies
to report on terrestrial ecotoxicology and worked with other
scientists to complete the risk assessment.
ardea’s principal role was to combine
the laboratory toxicity data with the field data to propose
representative bird species for the assessment, and to evaluate
the exposure and risk for these species.
Result: The final risk assessment was a comprehensive
document including environmental fate, marketing projections
and conclusions regarding risk to birds and mammals. ardea
contributed portions of text for the main body of the assessment
as well as complete appendices for support of the avian
exposure components of the assessment. |
