Wang Xiaojun, a professor of environmental engineering at South China University of Technology, said the bulletin by the provincial department of water resources indicated that government departments in the province still have a lot of work to do to meet their goals of curbing Guangdong's water pollution in the coming years.

"Relevant governments should expand investment in building and maintaining sewage-treatment plants, sewage networks and pipelines in the future," Wang told China Daily on Monday.

He attributed the province's worsening water pollution to the lack of investment in sewage treatment in some areas, particularly in the under developed and remote cities and counties in western, northern and eastern parts of the province.

Chen Guangrong, deputy director of the provincial department of environmental protection, said the Guangdong provincial government has promised to improve the water quality over a larger area in the future.
