Survival, growth,
and reproduction
of aquatic
community

Ingested dose and
response of
contaminants by
carnivorous ish

Carnivorous ish feeding at
the site ingest contaminants
at levels that signiicantly
inhibit critical biological
processes and organism
health

Conduct ish sampling to identify
primary carnivorous ish species
present or potentially present at
the site. Determine primary food
sources through examination of
gut content and literature review.
Collect representative specimens
of primary food sources and
measure concentration of
contaminants in tissue. Calculate
ingested dose of contaminants to
carnivorous ish and compare to
publish information of safe doses.

Quantify risk, and thus need for
remediation, to carnivorous
ish at the site. Identify
contaminants posing the risk.

Survival, growth,
and reproduction
of semiaquatic and
terrestrial
populations

Ingested dose and
response of
contaminants by
carnivores feeding on
ish or other aquatic
animals

Mammals, birds, and reptiles
feeding at the site ingest
contaminants at levels that
signiicantly inhibit critical
biological processes and
organism health

Conduct literature review and site
observations/surveys to
determine what animals
potentially at the site rely on the
aquatic food chain and their
primary sources of food. Collect
representative specimens of
primary food sources and
measure concentration of
contaminants in tissue. Calculate
ingested dose of contaminants to
animals relying on aquatic food
sources and compare to publish
information of safe doses.

Quantify risk, and thus need for
remediation, to mammals,
birds, and reptiles feeding at
the site. Identify contaminants
posing the risk.
