Koh Lan’s Green Waters: Waste and Plankton Bloom
Wastewater discharge on Koh Lan is identified as the primary cause of the plankton bloom that turned the sea smelly and green, according to the Department of Marine and Coastal Resources (DMCR). The situation was initially brought to attention when the Facebook page “We Love Pattaya” posted pictures of the unusually green seawater around Koh Lan, a popular island located 7 kilometers off the coast of Pattaya Beach.
