American-Cruise-Lines-Independence-Cruise-Ship (6:30 p.m. EDT) -- American Cruise Lines' brand-new ship, the 104-passenger Independence, made a cruising faux pas this week when it released gray waste water into the Maine waters as the ship was docked in Bar Harbor, reports the Bangor Daily News.

A company spokesman could not be reached for comment, but the news report claims the spill was accidental and only involved gray water (used water from sinks and showers) and not sewage. The water around the ship did contain high levels of bacteria, but was not expected to cause any public health problems. Environmental officials were notified of the incident, which took place around 10:30 a.m. EDT on Monday.

Independence, which sailed its maiden voyage in June, is spending the summer sailing seven-night Maine Coast & Harbors cruises.

Wondering how ships generally deal with waste water? Here's a rundown of onboard policies for the major cruise lines.
