<jats:p>Field tests of a sparker system demonstrated control of zebra mussels in an intake pipe. The sparker was implemented in a wet well near the exit of an intake pipe at a Georgia‐Pacific plant on Lake Champlain, N.Y. and was tested during the summer of 2003. The pressure was measured at several locations along the pipe, and zebra mussel samples were placed at those locations. Test results indicated that sparker pressure pulses can eradicate existing adult zebra mussels and prevent the settlement of larval stages. Sparker pressure pulses with peak pressures of at least 0.04 MPa and pressure energies per unit area of 0.16 J/m2 per pulse appeared to prevent the settlement of veligers. Peak pressures of 0.23 MPa and pressure energies per unit area of 5.8 J/m2 per pulse caused mortality of adult mussels.</jats:p>
