                    Figure 5.54 Pits where copper is surrounded by green deposits (19).


              The T-sections were free from pitting, and the inside surface was clean. The water
           samples contained a significant amount of iron-reducing bacterial activity. A signifi-
           cant extent of microbiologically induced corrosion because of the presence of bacteria
