但最影響香港的是，電文提及觀瀾河及石馬河水污染嚴重，經過兩年處理也未有改善，最後要切斷河道，阻止河水流入東江，以免影響對香港及廣州供水。那段電文內容如下：
「The Guanlan and Shima Rivers – Local residents call the Guanlan River in Shenzhen and Shima River in Dongguan the black dragon rivers due to discoloration from industrial and residential waste. Zhang Lijun, former vice minister of China’s State Environmental Protection Administration (forerunner of the Ministry of nvironmental of Protection), was reportedly shocked by the scale and magnitude of pollution in the two rivers on a January 2007 trip to Dongguan to inspect emissions. Even after mitigation efforts lasting several years and costing billions of renminbi, water quality in the two rivers is still poor. The rivers’ flows into the Dongjiang River had to be disrupted to prevent pollutants from contaminating an important source of the drinking water for Guangzhou, Hong Kong and other cities. 」
即是，有關報告電文已是2009年之事，而觀瀾河及石馬河水污染於2007年已發現，要到兩年後也阻止不了才截流，兩年間，有多少污水流入東江，甚至影響香港？url
