In September 1962, the U.S. Geological Survey was asked to appraise the water resources of the Salisbury, Maryland, area. The first phase of the study was concerned with an apparent iron problem in the city well field. It was theorized that the rusty water could have been the result of corrosion products. The corrosion process in natural waters is accelerated by increasing concentrations of dissolved oxygen (DO). Field determinations of DO and careful measurements for ferrous and ferric iron concentrations were made on all Salisbury production wells and on seven new test wells. Chemical analysis for major constituents in the water was also made on samples from selected sources. The measurements of DO and ferrous iron revealed that an unstable condition existed in the well field. Dissolved oxygen was present in all of the city wells and shallow test wells. Only the deep test wells contained no DO. Ferrous iron was found in ten of the city wells and in all of the test wells.
