JOMTIEN, Thailand – Oil-like residue that appeared on Koh Larn has now spread to Jomtien Beach. Local authorities say the affected stretch has been cleaned, but tourists should avoid contact with oil films and black clumps.
The source of the pollution is still under investigation. On Sunday afternoon, August 9, reports of oil-like residue emerged on the west coast of Koh Larn at Tien Beach and Samae Beach.
Residue covers over one kilometre
Small clumps and film-like deposits stretched across more than one kilometre, according to Thai media reports from Thairath and Daily News. Several swimmers came out of the water with black, oily residue on their bodies.
The exact composition and origin of the substance remain unclear. The Department of Marine and Coastal Resources tested affected areas and initially reported normal general readings for seawater quality.
Samples still being tested
Samples are still being analysed for residues of petroleum products. Reports of serious health complaints or allergic reactions have not been received so far.
Oil films and tar-like clumps should not be touched directly, as skin irritation is possible. Tourists should avoid affected water and beach sections, not swim in visible residue, and clean contaminated clothing or skin with water and soap as soon as possible. Local authorities should be informed about new discoveries.
said the Department of Marine and Coastal Resources.
Cleanup at Jomtien Beach
In a separate announcement in Thai, authorities reported oil-like residue of unknown origin at Jomtien Beach. Staff from the Pattaya City Environment Office collected the deposits and cleaned the affected area.
According to the announcement, officials will now investigate where the substance came from and how to prevent further pollution. The department urged the public to report new findings to local authorities.
