title: Arsenic in Nova Scotian groundwater.
abstract: The concentration of total soluble inorganic arsenic (i.e. arsenate plus arsenite) was measured in duplicate well water samples of 94 residents in Halifax County, N.S. An ammonium pyrrolidinedithiocarbamate-methyl isobutyl ketone graphite-furnace atomic absorption spectrophotometric procedure and also an automated hydride-evolution electrothermal-atomisation atomic-absorption spectrophotometric method were used to monitor the arsenic level in the ground water supplies. Of the 94 samples analyzed, 66 samples (70%) exceeded the Canadian maximum acceptable drinking water guideline of 50 ng As/ml.
