The fight continues in Nong Plalai against a polluted lake that smells like a toilet, with schoolchildren now enlisted to make “bio-balls” to purify the putrid water.
Sub-district officials have been battling the smell from the lake behind the Ching Wor Tai Factory near the SP4 since early December, first spraying ionic plasma enzymes onto the surface of the water and dropping hyacinth into the pond to clean it naturally. Neither method worked.
Mayor Pinyo Homklan and employees of the Public Health Section, volunteers and soil doctors from Sattahip on Jan. 17 then went to Nong Ket Yai School to teach students how to make 2,500 effective-microorganism balls to consume the sewage polluting the lake.
Pinyo cautioned that it will take time for the so-called “EM balls” to break up and interact with the pollutant. But, eventually, he said, they will bring the lake into equilibration.
The EM balls are made of soil, sand, ionic plasma, Super LDD 2 Microbial Activator, fine bran and molasses.
Residents blame the local plastic recycling factory for polluting the lake, which is more red, green and brown than blue these days. Ching Wor Tai denies all responsibility for the problem.
