Have you ever wondered how toxic elements like arsenic get into your well water? Do you know how many of New Hampshire's bedrock wells contain more arsenic than the EPA recommends for safe, potable water? If your well was one of them, would you know how to treat it?

Read through the graphic below to learn more about arsenic and well water.

State officials have shut-down one of three drinking water wells that serve the Pease Tradeport. The well was contaminated with an unregulated chemical found in foams used by firefighters.

Perflourooctane Sulfonic Acid, or PFOS, was found in the well which serves the 250 businesses and 8,300 employees of the Pease Tradeport. It was detected in levels that exceed a “provisional health advisory” level set by the EPA.
