Hin Kong Subdistrict will be the site of a 1,400 MW gas-fired power plant operated by SET-listed Ratch Group PLC.

Since at least 2001, villagers of tambon Nam Pu have complained about toxic wastewater from an industrial waste treatment plant they suspected of contaminating their water.

Wax Garbage Recycle Centre, an industrial waste treatment plant, began its operation in the upstream area of Nam Pu Creek about the same time as contamination became evident.

They also found high levels of volatile organic compounds (VOC) such as toluene, xylene, ethylbenzene, benzene and cis-1,2-dichloroethylene.
