The sample showed elevated levels of volatile organic compounds, predominantly benzene, that would explain the odor in tap water, officials at the plant said. The potential health risks are uncertain until further testing is complete, they said.

Humans are nearly halfway to damaging the environment so gravely that the Earth will cease to be a “safe operating space” for our species, reports a just-published article in the journal Science.
The paper, which is the work of an international team of 18 scientists headed by Will Steffen of the Stockholm Resilience Centre and Australian National University in Canberra, reports that four of nine “planetary boundaries” have been crossed as the result of human activity, meaning that we’re in big trouble in those areas.
