Potentially harmful heavy metals other than lead have been found in water samples at various public and private housing estates across Hong Kong, including nickel - a skin irritant - and cadmium, which can cause cancer....
WATER QUALITY IN CHINA
What do I need to know about water?
China’s water sources are among the most polluted in the world. A World Bank study found that 13 of the 15 major cities (including Shanghai) along the 7 main water source rivers in China are affected by severely polluted water.
The most common pollutants in Shanghai drinking water are high levels of chlorine, bacteria, and lead and toxic heavy metals. Shanghai’s water authorities have publicly acknowledged that tap water potability is compromised largely by secondary contamination from old piping. The heavy use of chlorine is necessary for disinfection, but is also unhealthy and can create carcinogenic byproducts[1]
Most Shanghai residents buy bottled drinking water but do not filter their showers. However, studies by the EPA and the Univ of Pittsburgh have shown that people absorb more toxic byproducts of chlorine through skin absorption or inhalation than through ingestion[2]
There are at least many different water purification technologies – what is right for you depends on the type of contaminant you want to remove, your desired water use, and your budget
What’s in the water?
About 80% of the water we get in Shanghai is from the Huangpu River.[3] The remaining 20% comes from the Yangtze River. Unfortunately, both are among the most polluted rivers in the world.
A weekly report released by the Environmental Monitoring of China agency on Aug 17, 2010 revealed that just two of the 18 monitoring stations along the Yangtze River graded the water quality as good.
According to Shanghai’s environmental protection bureau, the upstream area of the Huangpu River should be rated at class II, but is at class IV (suitable for industrial use only)[4]
The total volume of sewage discharged into the Yangtze river reached nearly 30 billion tons, including at least 9 billion tons of domestic sewage in 2005, according to an annual report by the Yangtze River Water Resources Commission.
On a bright note, there is a project underway to source water from the Qingcaosha Reservoir, near Chongming Island, but as of now, the project is not yet complete.
There are a number of potential pollutants and contaminants that may be present in local tap water:
General sediment and rust
Bacterial and viruses (Giardia and Cryptosporidium)
Chlorine and chlorine byproducts like Trihalomethanes (THM)
Nitrites and nitrates (pesticides, herbicides, etc.)
Heavy metals (Lead, Mercury, Aluminum, Cadmium, Chromium, Copper)
