S&T Project 19174 Final Report: Alternate Control Strategy for Dreissinids Using Electrical Methods

Zebra and quagga mussels (Dreissena ssp.) are major macrofouling species that impact the operations and maintenance of Bureau of Reclamation (Reclamation) water delivery systems. There is a need for an economical and environmentally safe control strategy for these invasive mussels within Reclamation structures. The primary objectives of this research project were to perform literature research and determine the feasibility of using electrical methods to mitigate zebra and quagga mussel infestations in Reclamation facilities. This project attempted to carry out a single established electrical testing procedure described in the literature to investigate the effectiveness of electrical control methods under field conditions similar to those found in Reclamation facilities. Multiple methods utilizing electricity have been shown to impact mussel behavior, including mortality and a reduction in the rate of byssogenesis (byssus attachment); however, a single method is chosen primarily on the basis of adaptability to small-diameter pipelines commonly found in Reclamation facilities. The method chosen for testing on this project involved high voltage pulsed electrified fields. Other methods, including direct electrical currents in the media (water), have also been identified in the literature as having the potential to prevent attachments to metallic surfaces, and these may be studied in the future after high voltage pulsed electrical fields have been assessed.
