    The frequency of detection of arsenic, iron, and manganese was compared between stratified-drift and the bedrock aquifers in the study unit. Water-quality data were available for 145 public-supply wells in stratified-drift aquifers in Maine, New Hampshire, and Rhode Island. These were compared to data from 607 bedrock public-supply wells in those same states (table 3). Arsenic, at concentrations of 0.005 mg/L or greater, was detected in 7.6 percent of the 145 public-supply wells in the stratified-drift aquifers and in 25.5 percent of the public-supply wells in the bedrock aquifers (fig. 5, table 3). Results of contingency-table analysis indicate that the detection rate of arsenic in
