Water Environment

Rivers

In the 59 provincial controlled river section in Guangdong, 31 of them meet the request of standards, stands 52.5%, 6.7% higher than last year. Water qualities of rivers are mainly belongs to grade II. 6 river sections are of excellent water quality, belongs to grade I and stands 10.5%, they are Heyuan section of Dongjiang River, Zengjiang River Liuxi River, Qinjiang River, Chaozhou section of Hanjing River and Xixi River; 23 river sections are of good water quality, belongs to grade II and stands 40.0%; 2 river sections are of fair water quality, belongs to grade III and stands 3.4%; 11 river sections are of average water quality, belongs to grade IV and stands 18.6%; 7 river urban sections are of bad water quality, belongs to grade V and stands 11.9% ; 10 river urban sections are of worse water quality, belongs to bad grade V and stands 16.9%, they are Nanshan River, Longgang River, Pingshan River, Foushan watercourse, Dongguan canal, Pear River Guangzhou section, Shenzhen River, Nianjiang River, Xiao Dongjiang River Maoming section and Xiao Dongjiang River Zhanjiang sections. River sections are of excellent to good water quality, are the mainstream of big river and the main watercourse in Pear River Delta, such as East River, West River, North River, Meijiang River, Hanjiang River, Moyangjiang River, and Tanjiang River. River sections of worse water quality are those flows through cities urban and cross CitiesRiver with a relatively small flow. Major pollution index is NH3-N, secondly are oil, aerobic organic compound and non-ionic ammonia, and showed obvious domestic and agricultural organic pollution features. Compared with last year, percentage of river sections reached standards is 6.7% higher, water quality of river sections meet request of or better than grade III is 5.1% more. The general water quality of provincial main rivers has been improved. River sections which integrated pollution index and water pollution that have been decreased are Xizhijiang River, Longgang River, Pingshan River, Jiangmen River, Shenzhen River, Nianjiang River, Juehuajiang River, Xiao Dongjiang Maoming section, Jiuzhou River and Nandu River. River sections that integrated pollution index and water pollution that have been increased are Foushan watercourse, MeixiRiver and Xiao Dongjiang Zhanjiang section. Water quality of other river sections has no obvious changes.

Xiao Dongjiang River Zhanjiang sections.

River Mouths and Near-coastalSea Region

There are Guangzhou, Shantou and Zhanjiang 3 cities of Guangdong, which separately monitored the river mouths' water quality of PearRiver, HanjiangRiver and JiuzhouRiver. All the water qualities of river mouths are beyond standards and the main pollution index is NH3-N. Compare with last year, river mouth water pollution of PearRiver and Jiuzhou Rive have been decreased, while mot much changes in the river mouth of HangjiangRiver.

There are Shenzhen; Zhuhai, Zhanjiang and Yangjiang 4 cities of Guangdong monitored the water quality of near-coastal sea region. All the urban sections, water qualities are beyond standards, except that of Yangjiang is within standards. Main pollution index of sections beyond standards are inorganic Nitrogen and phosphate. Compared with last year, Water pollution of Zhuhai section has been decreased, while not much changes in Shenzhen, Zhanjiang and Yangjiang sections.

changes in Shenzhen, Zhanjiang and Yangjiang sections.

Lakes and Reservoirs

Water quality of Xin Fengjiang Reservoirs keep stable, and has attained the water quality standard of grade I, are excellent water. All annual average values of monitoring index of Hedi Reservoir have attained standards, belongs to grade II. Water quality of Gaozhou Reservoir and XinghuLake are beyond standards, belongs to grade IV, exceeding items are total Nitrogen and total Phosphor. Compare with last year, water pollution of Hedi Reservoir has been decreased while that of XinhuLake has increased, and not much changes in Gaozhou Reservoir.
