In September 2013, 1,400 tons of molasses spilled into Honolulu Harbor. The spill was discovered on 9 September 2013.[2] It was caused by a faulty pipe that malfunctioned while the molasses was being loaded onto a ship,[3] for which the shipping company Matson Navigation Co. took responsibility.[4] Unfortunately, evidence suggests that this accident could have been avoided entirely. According to Randy Grune, a Department of Transportation Deputy Director, he sent Matson Navigation Co. a letter in July 2012, notifying them of a leak in their faulty pipe after he had inspected the ship. The senior executive at Matson, Vic Angoco, claimed that the company performed their own inspections on the pipeline, and did not find any leaks. However, Randy Grune claims that the leak he pointed out in 2012 was in the same spot that the pipe burst open when the incident occurred, resulting in 233,000 gallons of molasses being spilled.[5] Molasses is an unregulated product, and neither Matson nor government officials had a contingency plan to respond to a molasses spill.[2] Natural currents and weather were expected to eventually dilute and flush the molasses out of the harbor and a nearby lagoon.[6]
Right after the spill occurred, environmentalists shifted their focus to how this much molasses would affect the commercial harbor area. Ke'ehi Lagoon and Beach Park were also areas of concern.[7] Divers in the harbor area reported that all sea life in the area were killed by the molasses, which instantly sank to the bottom of the harbor and caused widespread deoxygenation.[8][9][3] Members of various coral species were injured or killed, and more than 26,000 fish and members of other marine species suffocated and died. 17,000 corals were also estimated to have been killed.[4][10] One diver named Roger White was sent down into the harbor to investigate the extent of the damage caused by the molasses, and his findings were as follows: "It was shocking because the entire bottom is covered with dead fish. Small fish, crabs, mole crabs, eels. Every type of fish that you don't usually see, but now they're dead. Now they're just laying there. Every single thing is dead. We're talking in the hundreds, thousands. I didn't see one single living thing underwater".[3]
This was a new challenge for environmentalists, as molasses acts in a much different manner than oil, which is a more common type of spill. Dave Gulko, a State of Hawaii Biologist, was also on site after the spill and stated the following: "Unlike an oil spill, which can be cleaned by skimming the surface, the molasses quickly disperses to the deepest points. It's sucking up all the oxygen."[7] To get a visual of this incident, Roger Smith, a scuba instructor who owns Cool Blue Scuba in Honolulu, gave an account of what he saw after the spill in an interview with National Geographic. Smith reported the following: "Usually the water has a greenish hue from the algae. But when I dove, it was brown, almost like a cola color. The molasses sunk down to the bottom, and it kind of blanketed everything. It sucks the oxygen out of the water. Every living thing is usually hiding in a hole. But every living thing came out and was gasping to live. Crabs, fish, worms, feather dusters... everything was just laying out in the bottom, just dead. The bigger fish had died, but they had gone to float to the top. The smaller fish were just on the floor."[11]
Why was there so much Molasses in Honolulu?
The Hawaiian Commercial & Sugar Company, which was founded in 1878 by Claus Spreckles, owns and cultivates sugarcane on 36,000 acres in Maui. With this much sugarcane, the company can produce around 200,000 tons of raw sugar and 60,000 tons of molasses per year. All of the excess molasses that is not used for livestock feed is shipped to California to be sold in grocery stores.[12] The shipping company that transported this excess molasses was Matson Navigation Company, who had been transporting molasses from Honolulu Harbor for 30 years, and at the time was shipping it about once a week.[2]
Aftermath
There was never any danger towards humans due to the molasses, unlike in the Great Molasses Flood (or Boston Molasses Flood) which killed 21 people and injured 150 others.[6] The danger of the Honolulu Molasses spill was caused by the effects of the molasses present in the water as it drastically increased the amount of bacterial growth due to the new abundance of sugar in the water. The other possible danger was the chance of increased predation activity from sharks, barracudas, and eels due to the copious amounts of deceased prey.[3] Another potential adverse effect was the chance for unusual growth of marine algae that holds its own plethora of negative environmental impacts.[3]
Some compare this molasses spill to the likes of an oil spill due to the devastation to marine life and the ecosystems that both induce. However, the cleanup process for a molasses spill is quicker and more efficient than that of oil spills. By nature, molasses is able to mix with water, and due to this fact, the bacteria that essentially do all the cleanup are able to access the molasses more readily than in the circumstances of an oil spill where there are big clumps of oil.[6] The other factor that aids in molasses cleanup is the number of bacteria that are able to break down sugar, compared to the number of bacteria that are capable of breaking down oil.[6]
