Arsenic has been reported in the drinking water wells of Sinkiang at
up to 1 milligram per m3. This is (slowly) being studied
the University in Urumchi. We hope to post details on the web
Yangzong Lake Pollution Abatement, Arsenic Removal and
Water Quality Restoration in Yunnan, China
1. Description of Yangzong Lake
Yangzong Lake is located at the boundary of Kunming City and Yuxi City. It is one of the nine plateau lakes in Yunnan. At the 1,770-m water level, the lake covers an area of 31 km2, with the average water depth at 20 m and the water storage volume at 604 million m3. The lake has a catchment area of 192 km2. Since 2008, the lake has been found to be polluted by arsenic. The current average arsenic concentration in the lake water is 0.128 mg/l.
2. Key Objective of the Project
The Project is expected to lower the average concentration of arsenic in the lake to ≤ 0.05 mg/l within a period of three year, by determining the arsenic loading from groundwater into the lake, and by controlling the average concentration of arsenic in the groundwater flowing to the lake to ≤ 0.1 mg/l through mature, safe, effective and feasible technological and engineering measures such as blockade, abatement, absorption and separation.

Arsenic has been reported in the mines of Yunnan province for over 30 years. Many lung cancers were seen among the miners, many of whom were children. But it is hard to distinguish the cancers caused by radon gas and those caused by arsenic.
