It is commonly observed that most bacterial corrosion in waterfloods occurs as pit corrosion. A hypothesis has been advanced to explain a portion of the mechanism underlying bacterial pit corrosion and a suggested method has been presented for determining the possible relationships between the general microbial flora and microorganisms capable of participating in pit corrosion. Topics discussed include role of sulfate-reducing bacteria, correlation between bacteriological examinations and corrosion damage, cultural techniques, laboratory and field evaluation techniques, and detection of sessile microorganisms.

A
Gallionella
sp. is described that lives and freely multiplies in sea water. The habitat of the organism has been thoroughly investigated and the possibility of accidental occurrence has been eliminated. The appearance of the
Gallionella
sp. described is quite different from the similar iron bacteria occurring in fresh water.
This article focuses on the AWWA Organic Contaminant Control Committee (OCCC), whose mission is to evaluate current treatment practices and disseminate knowledge to the water industry on methods to control organic contaminants. The committee looks to regulators, industry professionals, consultants, and academia to identify organic contaminants of concern and current control practices. The OCCC is composed of water industry representatives from both the United States and Australia along with consultants, academics, and regulators. The most recent developments have included two informative websites on methyl‐tertiary‐butyl‐ether (MTBE) and endocrine disruptors and the sponsorship of special topic sessions on algal toxins and Contaminant Candidate List (CCL) organics. The committee is currently focusing its attention on metolachlor and disinfection byproducts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
