All You Need to Know About Greywater Discharge From Ships - Ocean Conservation News
"Spoiler alert: it is some really gross stuff"
What's greywater?
"The International Maritime Organization defines it as “the drainage from dishwater, shower, laundry, bath and washbasin drains.” At first glance, this may not seem as bad as drainage from toilets (i.e. sewage), but surprise, it is! While people understand the dangers (and let’s face it, the general grossness) of untreated sewage, few realize that untreated greywater can be just as nasty."
Sarah Bobbe of Ocean Conservancy explains what greywater is, compares greywater to sewages, and how passenger ships (like cruise lines) are the biggest contributer to greywater being dumped into marine ecosystems.
"The EPA found sewage discharge rates on passenger vessels to be 8.4 gallons per day per person, while greywater discharges total anywhere from 45 gallons per day per person to 65 gallons per day per person."
Dumping raw greywater may be a neccessity still for the majority of sailors but cruise lines have the ability and funding to ehance their greywater waste systems, and should.

🐬🐬🐬Donate to the Dolphin Project 🐬🐬🐬https://www.dolphinproject.com/donate/
Dolphin Project is a non-profit charitable organization, dedicated to the welfare and protection of dolphins worldwide. Founded by Richard (Ric) O’Barry on Earth Day, April 22, 1970, the organization aims to educate the public about captivity and, where feasible, retire and/or release captive dolphins.
The mission of Dolphin Project is to end dolphin exploitation and slaughter, as dolphins are routinely captured, harassed, slaughtered and sold into captivity around the world – all in the name of profit. Dolphin Project works not only to halt these slaughters, but also to rehabilitate captive dolphins for retirement and/or release, investigate and advocate for economic alternatives to dolphin slaughter, and to put a permanent end to dolphin captivity.
Port Sundries is not affiliated with Dolphin Project but supports their goal 100%.
