A new study from the US Geological Survey estimates that as many as 80,000 people in Southeastern New Hampshire could be drinking water from wells with unhealthy levels of contaminants.

The study finds nearly 50,000 people could be drinking elevated levels of arsenic, nearly 15,000 with manganese, and fewer than 10,000 could be consuming either high levels of uranium and lead.
