An Assessment of Metals Contamination in Lake Roosevelt.
Entry ID: BESTsed15

Abstract: In response to reports of elevated metals concentrations in fish and
other environmental samples from Lake Roosevelt, Ecology conducted a
series of field surveys between May and September 1986 to determine
the extent and significance of contamination (Johnson et al. 1988).
Sediment, water samples and a variety of fish species were used in
this assessment. These data were also summarized in a ... View entire text

Quality The accuracy and precision of the metals data were assessed by
analysis of standard reference materials, laboratory duplicates field
replicates and field blanks. Results were in good agreement with
certified values. No data were qualified.
