From abstract: This report presents chemical-quality data collected from May 1980 to January 1981 at several locations within the Delaware River estuary and selected New Jersey tributaries.

Partial abstract: The purpose of this study is to define the reliability with which results of tests conducted in a physical model of the Delaware River Estuary can be used to predict the effects of modifications to the estuary. The Delaware River model at the Waterways Experiment Station was used to conduct tests to predict the effects of the navigation channel enlargement between Philadelphia and Trenton, and the results of the tests are compared with subsequent prototype data to determine the accuracy of the model predictions.

The following report covers a reconnaissance for radioactive materials that was made in parts of Maine, New York, New Jersey, and Pennsylvania. It's primary objective was to examine the iron ore deposits and associated rocks in Adirondack Mountains of New York and the Highlands of New Jersey. Additionally, several deposits known or reported to contain radioactive minerals were examined to delimit their extent. However, most of the deposits examined are not significant as possible sources of radioactive elements and the data pertaining to them are summarized in tables provided.
