The town of Rollinsford holds a forum Monday night on long-standing concerns about its drinking water.
Residents in the local water-sewer district say their tapwater is often discolored or has a chemical smell.
The water comes from three local wells and runs through six miles of pipe, some of which dates to the late 1800s.
An engineering analysis says the system could need millions of dollars in new infrastructure and treatment.
Residents can weigh in on the state of the water system tonight at the local library at 6:30pm.
The forum will include local and state officials, and researchers from UNH.
