Noncancer subsistence-level doses were calculated using the following formulas:
child dose = (second-tier screening concentration×0.02 kg/day×365 days/year×6 years)/(13 kg×(365 days/year×6 years))
adult dose = (second-tier screening concentration×0.065 kg/day×365 days/year×30 years)/(70 kg×(365 days/year×30 years))
Noncancer recreational-level doses were calculated using the following formulas:
child dose = (second-tier screening concentration×0.003 kg/day×365 days/year×6 years)/(13 kg×(365 days/year×6 years))
adult dose = (second-tier screening concentration×0.008 kg/day×365 days/year×30 years)/(70 kg×(365 days/year×30 years))
The second-tier screening concentrations are rounded.
CMRL = chronic minimal risk level (ATSDR)
conc. = concentration
IMRL = intermediate minimal risk level (ATSDR)
mg/kg/day = milligram per kilogram per day
ND = not detected
ppm = parts per million
RfD = reference dose (EPA)
spp = species
Unknown = "unknown aquatic animal"

Cancer subsistence-level doses were calculated using the following formula:
dose = (second-tier screening concentration×0.065 kg/day×365 days/year×30 years)/(70 kg×(365 days/year×70 years))
Cancer recreational-level doses were calculated using the following formula:
dose = (second-tier screening concentration×0.008 kg/day×365 days/year×30 years)/(70 kg×(365 days/year×70 years))
The second-tier screening concentrations are rounded.
conc. = concentration
mg/kg/day = milligram per kilogram per day
NA = not available
ND = not detected
ppm = parts per million
spp = species
Unknown aquatic = "unknown aquatic animal"

Noncancer doses were calculated using the following formulas:
child dose = (second-tier screening concentration×0.001 kg/day×365 days/year×6 years)/(13 kg×(365 days/year×6 years))
adult dose = (second-tier screening concentration×0.002 kg/day×365 days/year×30 years)/(70 kg×(365 days/year×30 years))
The second-tier screening concentrations are rounded.
CMRL = chronic minimal risk level (ATSDR)
conc. = concentration
mg/kg/day = milligram per kilogram per day
ND = not detected
ppm = parts per million
RfD = reference dose (EPA)
All chemicals detected in game species caught on site were evaluated for noncarcinogenic effects only—cancer screening guidelines are not available for these chemicals.

Cancer doses were calculated using the following formula:
dose = (second-tier screening concentration×0.0016 kg/kg/day×365 days/year×30 years)/(365 days/year×70 years))
Risk was calculated by multiplying the cancer dose by EPA's oral cancer slope factor.
The second-tier screening concentrations are rounded.

NA = not available
