A variety of metals and surface modification techniques were evaluated for corrosion and biofilm resistivity. Coupons contacted water in a parallel-flow manifold test bed. System water was obtained from a water well with a chronic history of fouling and corrosion. Several surface types resisted corrosion, however, no metal or surface modification prevented attachment of bacteria as revealed by epifluorescent microscopy or classical culturing techniques. Many of the bacterial surface isolates could not be identified using available technology. Different surfaces did result in modified bacterial consortia.
