Marine and freshwater pollution caused by the transport of invasive species in shipping ballast water is a major global problem and
will increase in magnitude as the shipping of commodities increases in the future. An economical method to preclude biological
organisms in the seawater used for ballast is to exclude them at the source port. Integrated natural filtration using onshore wells or
seabed gallery systems has been thoroughly investigated for use as pretreatment for seawater desalination systems and has proven
to be environmentally acceptable and economic. Thus, the use of this proven filtration technology to another issue, ballast water
treatment, is an innovative method of providing marine organism free seawater by non-destructive means in port-based facilities.
This method is ecosystem-friendly in that no chemicals or destructive processes are used. Design and construction of well or
seabed gallery intake systems for the production of ballast seawater are feasible in virtually all global port facilities
