New Law Signed: Ballast Water Treatment

The Governator just signed a law that will require treatment of ballast water from both small and large ships- the problem being those ships ballast waters often contain non- native plants and critters that often end up establishing themselves in California waterways.

This is probably long overdue. My question is, how are they going to "treat" that much ballast water? I guess even the powers that be don't know yet, as they have until 2020 to come up with some standards. Anybody have any ideas on how they might end up treating all this ballast?

Let's hope the cure doesn't end up worse than the disease.
