A new study published in the US-based Proceedings of the National Academy of Sciences shows that 65% of drinking water wells in one region of Âu Lạc are at risk of containing unsafe levels of arsenic and other harmful substances.
Dr. Michael Berg, senior scientist at the Swiss Federal Institute of Aquatic Science and Technology, co-authored the study which estimates that some seven million people in the southeast Asian country are at risk.
In addition to arsenic, which is toxic and can cause vomiting and anemia as well as cancer of the skin, lungs, bladder and kidneys, about 44% of the wells contained unsafe levels of manganese, with an estimated five million people who might be affected.
Manganese at high concentrations can damage children's intellectual ability. The risk of harmful contamination has increased in recent years due to unsustainable water use combined with climate change effects such as desertification caused by prolonged drought.
Dr. Berg, in cooperation with Hà Nội University of Science and Technology, has created a groundwater map that shows safe water sources, which Aulacese (Vietnamese) officials intend to use as a tool to provide alternate clean water supplies.
Our sincere thanks, Dr. Berg and associates for this revealing study and your work with the Aulacese government to protect the public from such grave contamination-related diseases.
Let us endeavor to live in greater harmony with nature to ensure the health of both humans and the planet. During a December 2010 videoconference in Dubai, United Arab Emirates, Supreme Master Ching Hai spoke about similar issues of imbalance and encouraged government measures to minimize environmental harm.
