Wong Amat is the first of the area beaches to get a scrubbing. Similar work is planned on Jomtien Beach, the Naklua bridge area and around the Dusit curve on Pattaya Beach.
Suthee said seasonal currents were responsible for bringing the stones ashore. The rock will be used as landfill in the national sports stadium site in Jomtien Beach.
Over 100 city workers are put to work removing dirty rocks from Wong Amat Beach.
