Page 7 - Monthly bulk precipitation samples were collected from 18 sites in New York, Pennsylvania, and New England during periods that lasted from 12 to 36 months. The samples were then analyzed for calcium, magnesium, sodium, potassium, ammonium, hydrogen ion, bicarbonate, sulfate, chloride, nitrate, and phosphate. The analytical results were combined with precipitation amounts to get annual average loads of the various ionic species as thousandths of a ton per day per square mile. The loads of certain...

The calculated radium-solute load for the sampling period ranged from about 2.5 X 10~" pounds for the Nezinscot River to 25,000 X 10~" pounds for the Mississippi River.
