[ Update this Record ]

Summary
Abstract: The spatial distribution of arsenic concentrations in ground water of the
Willamette Basin was assessed by analyzing data from 728 historical and project
sites. Concentrations of arsenic ranged from < 1 to 2,000 mg/L (micrograms per
liter). Concentrations in 58 (8.0 percent) of the samples exceeded the U.S.
Environmental Protection Agency (USEPA) current Maximum Contaminant Level (MCL)
of 50 mg/L. ... View entire text

Quality All 12 project field equipment blanks yielded arsenic concentrations
below the MRL of 1 5g/L. These results indicate that field and
laboratory methods were noncontaminating. The coefficient of
variation (CV) (standard deviation divided by mean, expressed in
percent) for each of the six sets of project triplicate split samples
ranged from ... View entire text
