Abstract
Ground-water contamination problems resulting from the disposal of oil-field brines has been the subject of many papers. An area just northeast of the City of Delaware, Ohio has suffered this type of contamination and was the subject of research by two Ohio State University graduate students. During the year 1969, the Delaware area was studied again to see if the chloride ion concentration in the ground-water had diminished as predicted in one of the earlier theses. Monthly water samples were obtained followed by an analyses for the chloride ion for each sample. Also, water level measurements were made at the time the water samples were obtained. Boster (1967) predicted that the chloride ion concentration would be in accordance with the Public Health Service's standards for drinking water during the years 1969-1972. The results of this study clearly show that the chloride ion concentration in the ground-water is dependent upon precipitation and the quantity of residual salt in the interstices of the strata above the water table. The contamination of the ground-water in the Delaware area is not clear in 1969 and will not be clear in 1970. The only certainty is that the chloride ion concentration in the ground water is slowly dissipating with time.
