Should I report this company for polluting?

I work for a commercial cleaning company. I work at an office building. They are an internet provider. They have their own trucks and stuff. A few days ago I saw one of the employees wiping down one of the trucks out back. I went inside and came back out. And I saw soap running off into the storm drain. I heard this is bad because the soap will cause algae to bloom in the creeks and rob oxygen of fish. Should I report them for doing that? I understand they've got to wash their trucks, but they could always go and do it at the car wash in town.
