| Note générale : |
During the period from october 1978 to march 1981, the U. S. geological Survey assessed the river quality of the Schurykill River bassin in Pennsylvania from the headwater to th Fairmount dam at Philadelphia. Then, this report is part of Schurylkill river quality assessment. The study had three objectives : (1) to determine the distribution of trace substances in the Schurylkill river and its tributaries through analyses of streambed sediments, (2) to determine the average annual transport of trace substances including dissolved and total trace metals, from major tributaires and reaches of the river and (3) to determine the frequency with which concentrations of selected consituents exceed federal and state water quality criteria... |
