Where might zebra mussels attach and need to be monitored within a facility's water conduits? Any submerged area with a moderate flow rate that draws water from an infested water source is vulnerable to colonization, especially one that offers protection, such as a crevice or seam. Intake screens, for example, are common settlement areas and are often coated with clumps or "druses" of mussels. Most facilities have numerous components subject to severe biofouling, including:
The following sections will provide descriptions of two different facilities that are susceptible to mussel fouling. Each example includes pictures and/or diagrams of the site or facility, components of particular concern, as well as suggested monitoring methods.
Additional information on susceptible components in hydroelectric facilities, public facilities, navigational facilities, and floating plant facilities can be located in the Control Options By Facility section.
