Review of Soils Design, Construction and Performance Observations Overbank Structure Old River Control. Appendix A: Pumping Tests and Well Cleaning Operations, 1966.

Abstract

This is the first in a series of reports presenting the results of tests performed at intervals of several years on the relief wells at the overbank structure near Natchez, Miss. The tests, performed in 1966, included well pumping tests, analysis of well water samples, and well sounding and cleaning. These tests were conducted to determine the extent to which the efficiency of the relief wells had decreased since their installation in 1957 and to clean by surging those wells with specific yields of 80% and less of their original yields. Chemical analyses of well water samples indicate that the water is somewhat corrosive and contains a large amount of iron. In the presence of bacteria, incrustation or tuberculation of the well screens may occur under these conditions.
