Beijing Water Reservoir Contains Dangerous Levels of Lead

Quartz reported that researchers from the Chinese Academy of Sciences and the Australian Rivers Institute found that a significant water reservoir in Beijing was found to contain dangerous levels of lead.
As quoted in the publication:

Between 2007 and 2010, the Danjiangkou reservoir contained 200 micrograms of lead per liter of water—20 times higher than levels considered safe by the World Health Organization. The study also found “dramatic increases” of nitrogen, ammonium, and chromium, as well as arsenic.

The researchers did not say whether those levels persist today. In June, Chinese authorities said that over 70% of the time, lead levels in the reservoir remained below 10 micrograms per liter, meeting the national standard of 50 micrograms per liter.
