![]() And many cruise ships lack the sewage treatment facilities to adequately filter out toxins. This sewage is not only full of human waste, but also chemicals, pharmaceuticals, bacteria, viruses, heavy metals, and hazardous waste. More than a billion gallons of sewage are dumped into the ocean annually. There are a few places like Puget Sound, California, and most of New England where no-dumping zones have been created but everywhere else, sewage can be dumped. Beyond that point, there are no restrictions for dumping untreated, raw sewage in U.S. ![]() allows cruise ships to dump treated waste into the ocean if they are within three and a half miles from shore. To get into a few more specifics than above, the U.S. These scrubbers emit acidic wastewater that is warmer than ambient sea water and contains heavy metals, polycyclic aromatic hydrocarbons (PAHs), suspended particulate matter, and nitrates, all of which are harmful to the marine environment. And the water used in the “scrubber” process is then discharged into the ocean adding more pollution to the already polluted waters. This allows the cruise liners to continue to burn cheaper, more harmful fuel. So cruise ships have implemented using scrubbers to “clean” their dirty fuel air emissions. And their smokestacks must be cleaned to remove the harmful elements from the exhaust. Cruise ships not only dump sewage and food waste, but they also dump harmful fuel waste into the oceans as well.Ĭruise ships often use cheap, dirty, heavy fuel to power their engines. We’ve put together some of the most frequently asked questions about cruise ship waste to help illustrate the pollution these floating cities cause. Commonly Asked Questions about Cruise Ship Waste Guess who doesn’t have a say in the matter? The oceanic wildlife that call the oceans their home. And it also means that food waste is also dumped into the ocean. It means that waste from toilets is discharged into the water. ![]() That means that dirty water from sinks and showers and laundry facilities are discharged into the water. ![]() It allows cruise ships to dump waste into the ocean as long as the ships are more than three and a half miles offshore. laws do not do enough to protect our bodies of water. If you guessed a large portion of it ends up in the oceans, you’d be correct. And with all those people aboard, a looming question remains: what happens with all the waste from cruise ships? Cruise ships entertain thousands of passengers and are staffed by a substantial crew. ![]()
