New Hampshire’s Department of Environmental Services has recommended a more protective limit for the amount of arsenic in drinking water provided by public water systems.

The department proposes a new limit of 5 parts per billion. It has been enforcing a limit of 10 parts per billion, which was established by the U.S. Environmental Protection Agency in 2006. Before that, the limit was 50 parts per billion.
