Title:

BACTERIAL CORROSION OF STEEL CULVERT PIPE IN WISCONSIN

Accession Number:

00450736

Abstract:

An ongoing project to investigate culvert corrosion in Wisconsin has indicated that anaerobic sulfate-reducing bacteria were a contributing factor in the corrosion of galvanized steel culvert pipe at 31 percent of the culvert sites examined since 1972. Two corrosion products and two environments of corrosion are characteristic of bacterial corrosion. One association is oxidation scale, which is related to bacteria active in organic, poorly drained soils of nearneutral pH. The other is nodular oxidation, which is related to bacterial colonies on the pipe surface associated with a water source of nutrients and characterized by local perforations of the invert, particularly along the flow lines. In this paper field tests are discussed and a description of the occurrences is given.
