The First Naval Area Command is expected to find out what caused oil slick on the beach in Prachuap Khiri Khan province.
According to Hua Hin authorities, the oil was discovered yesterday along the beach in the tourist district of Hua Hin. Food vendors in the area reportedly smelled the oil a couple of days before it was washed up on the beach.
The authorities have not ruled out any cause yet. A sample of the oil slick has already been taken to the lab to determine the type of oil. The First Naval Area Command will survey the coastline and try to find whether there is a large vessel nearby.
Tourists have been told not to swim in the sea for a couple of days or until the beach is clean. Sand has been used in removing the oil slick. Hua Hin officials and related agencies will also take to the beach today to help get rid of the remaining oil slick.
